As a result of the vote to leave the European Union, party politics as usual, if there ever was such a thing, has been shaken. The referendum itself and the ensuing debate about Brexit has exposed the instabilities, contingencies and fragilities at the heart of the main parliamentary parties. We do not yet know what the effect of this will be, but British political parties face key challenges and opportunities as a result, and how they respond to them could have major implications for them and for the shape of the party system.
A glance back at British political history tells us that the structure and configuration of political parties has been periodically subject to this kind of flux and instability at times of social and economic change, leading to sometimes significant reconfigurations or reorganisations of the party system. In 1832, for instance, an organised Tory party first emerged out of the process of resistance to and the aftermath of the Great Reform Act, establishing what we would recognise as a two party system, with a government opposed by a ‘loyal opposition’. The ensuing need for competitive appeal to voters and the emergence of ‘Liberal’ and ‘Conservative’ labels brought the party system into the modern age. Following the First World War and the ‘confusion’ of parties that emerged from it, the changing social and political landscape, including the emergence of class and the decline of religion as key political dividing lines and the extension of the franchise saw in the 1920s the decline of the Liberals and the rise of Labour as the main alternative to the Conservatives, a rise interrupted by a split in the party over its handling of depression and economic crisis in 1929-31 and the formation of the National Coalition. The collapse of the post 1945 consensus, following the failures of Wilson, Callaghan and Heath governments in the 1970s to address Britain’s economic and industrial problems led to the emergence of Thatcherism, a split in the Labour Party and the formation of the SDP, as well as the emergence of the Scottish and Welsh nationalist parties and the Liberal revival in the 70s, giving shape to the politics of the last thirty years.
What each of these developments have in common is that in the face of major political or economic crises, the existing party configurations, allegiances, alliances, positions proved inadequate and some kind of realignment, if not inevitable, became necessary. It is tempting in such circumstance to imagine that the hand of history is at play and that there is little that can be done to arrest the inevitable consequence of it. However, history is not something that is done to us, but something in which we participate. The political world just like our social environment is in ‘constant process and transformation’ a process of ‘perpetual motion’ and history is ‘a series of specific events’ in which we are ‘consciously involved and … can consciously influence’. Thus, outcomes that seem inevitable in retrospect, like the emergence of the two party system in the first place, like the decline of the Liberal Party and the rise of the Labour Party are not necessarily so. Crucially, the contingencies, the avoidable errors and unexpected successes can be at least as important. The response to such events therefore is crucial to the effects that they have. Thus the political virtuosity with which political leaders and politicians respond to the Fortuna of events can have profound consequences.
For British political parties, then, the aftermath of the referendum may be one of these moments. Brexit presents challenging issues and potential opportunities for parties’ stability and success. It has presented challenges for party leadership and management by exposing or sharpening existing divisions and creating new ones, opening questions about future direction.In this short article, I will briefly outline some of these issues and what they might mean for the parties.
Conservative Issues, Challenges and Opportunities
The first challenge that the Conservative Party faces is trying to find ways to bridge its continuing divisions in the party over Europe. Tensions over Europe in the party are deep and persistent and it was David Cameron’s attempt to do just this that gave rise to the referendum in the first place. The increasingly Eurosceptic make-up of the Parliamentary Conservative Party meant that whilst those who could be called ‘Europhiles’ had greatly diminished in number, the most significant division in the party now emerging was between ‘soft’ Eurosceptics, who supported membership but argued that integration should go no further, and an increasingly vocal band of ‘hard’ Eurosceptics, who advocated withdrawal altogether. Cameron’s attempts to appeal to this arguably stoked the problem rather than healed it. His 2005 leadership campaign promise to withdraw from the centre-right European People’s Party in the European Parliament was fulfilled (after some prevarication), but the pledge of a referendum on the Lisbon Treaty was deemed irrelevant following its ratification in 2009. In January 2013, Cameron was effectively forced into conceding a referendum (dependent on a Conservative majority) after 81 MPs defied the party whip to vote in favour of one following a Backbench debate in the House of Commons. It was clear that Cameron’s move had failed abjectly to dampen the growing Eurosceptic revolt when in May, 116 Conservative MPs rebelled on the Queen’s Speech, by voting for an amendment ‘regretting’ the absence of a referendum bill from the government’s legislative programme. Party leaders were forced to allow backbenchers a free vote and even ministers were permitted to abstain.
When Cameron won his unexpected majority in 2015, he had to deliver on his referendum promise. However, the effect was to galvanise Eurosceptic MPs by providing both a unifying focus for an otherwise unorganised group with differing aims and motivations, and leadership, which it had lacked up to this point. The decision of both Michael Gove and Boris Johnson to support the Leave campaign, brought high profile, mainstream ‘big hitters’ with a strong public appeal and significant communications skills to the Leave side. This was made easier, moreover, by Cameron’s insistence during the referendum campaign that he would not engage in ‘blue on blue’ attacks, a source of frustration for some on the Remain campaign team, as Craig Oliver’s recent memoir on the referendum campaign attests. Nevertheless, much of the media coverage seemed fixated on the divisions in the Conservative Party anyway, a substantial amount of it through the prism of whether Cameron was likely to Remain leader or not afterwards. Thus, whilst the referendum did not create new divisions in the party, it focused, sharpened and exposed them.
Although the party’s claim to be the ‘natural’ party of government is not as strong as it was, the Conservatives were able to find a unity of purpose in its desire and instinct to govern. In the immediate aftermath of the referendum, it looked as if the party might have lost sight of this, but in the end it was able to settle the leadership relatively quickly following Cameron’s resignation after the referendum defeat. Conservative leadership election rules give party members a choice between two potential leaders whittled down by MPs. Given the Eurosceptic bent of the party’s relatively small membership of around 150,000, the post-Brexit leadership contest held potential to reinforce a grass-roots revolt by presenting members with the possibility of voting for a vocal supporter of ‘Hard Brexit’. In the end, however, the inheritors would not be the architects of the Leave campaign. Michael Gove’s ‘knifing’ of Boris Johnson ended his candidacy before it even began but it did Gove no good either who was eliminated, just as Liam Fox and Steven Crabb had been in earlier rounds. Members were therefore left with a choice between Theresa May, Home Secretary since 2010 and a Remain supporter, albeit a relatively reticent one (as Craig Oliver’s account of the campaign attests), and Andrea Leadsom who had come to prominence as a high profile and effective advocate for the Leave campaign. Given the orientation of the membership, there was every possibility that Leadsom might win, a potential result that could have put the parliamentary party and the party in the country at loggerheads. However, it was never put to the vote. Leadsom withdrew from the contest stating that she could not justify going to the membership ballot with support from only 25% of MPs. Theresa May, was installed quickly as the new party leader and prime minister on 13 July just a few days after the contest officially began, displaying the strong instinct for survival that characterises the Conservative Party’s staying power and success.
The Conservative Party, therefore, in sorting out the leadership swiftly demonstrated that it had not lost touch with what it has seen as its historic purpose above all, to govern. Leadsom standing down meant, first of all, that the party was spared the possibility of a ‘revolt’ by members which may have created further crises; secondly, that leadership and therefore some direction on Brexit could be established quickly – curtailing the possibility of continued political limbo and uncertainty over the summer period; thirdly, it meant that an impression of strong leadership could be given to contrast with the divisions in the Labour party that had exploded into public view in the aftermath of the referendum and used to the party’s advantage.
May, moreover, came through looking like a reassuring, mature, statesmanlike figure. She won appearing to be above the fray, without apparently getting her hands dirty, by sitting back and allowing her rivals to self-destruct. She was perhaps not so much the winner as the last one standing when the firing stopped. She was also in many ways the ideal unity candidate. She supported Remain, but took a cautious, low profile during the referendum campaign, and on assuming the leadership insisted that ‘Brexit means Brexit’, appointing prominent Eurosceptics to the key positions coordinating the process of exit. Thus, it seemed possible that divisions over Europe might finally have been put to rest in the Conservative Party. Perhaps the party would finally stop ‘banging on about Europe’ (as Cameron had always wanted) and begin to show some unity of purpose behind a new leader with a clear sense of direction. Now that this issue of EU membership had been resolved, the party could come together in the interests of the nation.
However, despite the initial truce, there is, as yet, no sign of the divisions coming to an end. Post-referendum, the distinction between hard Eurosceptics and supporters of membership have transmogrified into an emerging division between supporters of ‘hard’ and ‘soft’ Brexit which has created some further party management issues for the new Prime Minister. Analysis of recent parliamentary debates reveals that Hard Brexiters have made a range of different arguments, some taking an economically liberal line, based on global free trade and a competitive open economy based on low-tax and low-regulationwhilst others take a more ‘nationalistic’ position more directly resonant with the ‘taking control’ mantra of the Leave campaign, interpreting the referendum result as a vote for control over borders (against free movement), finances (against paying fees) and law (against the European Court of Justice) which rules out remaining in the single market under any terms since it would represent a ‘betrayal’ of what the British people had voted for. ‘Soft Brexit’ supporters on the other hand disagree. The strongest line is taken by ‘single marketeers’ whose arguments are oriented around the economic importance of being part of such a major free market, including a defence of the free movement of labour. Others are more pragmatic, expressing concerns about the impacts that the UK extricating itself from key arrangements and institutions like the single market might have on specific sectors, businesses, and industries, seeking assurances that their needs are fully understood. Thus the referendum has clearly not put the issue of Europe to rest in the Conservative Party and, if anything, the divisions between ‘Hard’ and ‘Soft’ Brexiters have become fiercer and hardened by the constitutional dimensions about the role of parliament that are emerging as part of this debate. Hard Brexiters have tended to argue that the referendum result is a clear instruction for complete withdrawal (i.e. ‘Hard Brexit’) and does not require any further interpretation or debate in Parliament,which has in any case delegated its sovereignty to the people in this matter. The latter, on the other hand, have argued that Parliament must play role in providing a mandate to the government as demanded by established constitutional practice and to provide the public with confidence in the integrity of the process. The divisions in the party are only strengthened by these more procedural dimensions and – as contributions to Parliamentary debates show – underlined by mistrust. ‘Soft Brexiters’ are accused of using arguments about parliamentary sovereignty to frustrate the process and undermine the will of the British peoplewhilst ‘Hard Brexiters’ are, in turn, are accused of seeking to bypass Parliament’s ‘historic’ and constitutional role as a sovereign body because it is unlikely to come up with an answer that they would like.
The party leadership has attempted to navigate these continuing divisions by maintaining a reticence on the detail of how it wishes to proceed with Brexit and what the outcome should be. The Government has been accused therefore of having no discernible plan, whilst claiming that revealing its negotiating hand to parliament will weaken its position. This may be so, but there are also likely to be important party management reasons for this reticence too. Revealing the government’s position is bound to incur the wrath of one side or another in the debate and may yet precipitate further splits and even endanger her own position as leader. After Thatcher and Major, the issue of Europe has dispensed with a third Conservative Prime Minister. There is, as yet, no guarantee that it will not dispense with a fourth.
Labour Issues, Challenges and Opportunities
An important advantage that the Conservatives have, however, is that the opposition is also divided on at least three levels. Firstly, there are and have been growing divisions within the party between the mainstream majority of the parliamentary party and the party membership which has been most clearly exposed by the election and re-election of Jeremy Corbyn as the party’s leader. He was not even expected to get on the ballot but a campaign by constituency activists to persuade enough MPs to nominate him (he needed 35) in order to ‘widen the debate’ worked. That he went on to win illuminated the fact that many members and supporters, old and new, profoundly disagreed with the direction of the party and rejected the implied prescription of other ‘mainstream’ leadership candidates that the Labour Party had lost in 2015 because they had, under Ed Miliband, been too strongly associated with an anti-austerity position. Indeed, it appeared that the majority of the party’s electorate felt the opposite and thanks to rule changes made by Miliband, MPs (and trade unions too) lost the weighted votes that the old electoral college system gave them and could now more easily have a leader they did not want imposed upon them.
That this happened means there is now also a stark division, secondly, between much of the Parliamentary Labour Party – whose ideological positions range from a small group of so-called ‘Blairite’ reformists, to mainstream ‘soft left’ MPs – and the leadership, which now is effectively in the hands of key members of the left-wing Campaign Group. Any attempts to paper over this division fell apart spectacularly in the aftermath of the Referendum. Corbyn’s support for the Remain campaign during the referendum was regarded by many party moderates as somewhat lacklustre and equivocal at best and his reported initial response to the result that Article 50 should be triggered ‘immediately’ was greeted with incredulity by a number of Labour MPs who supported the Remain campaign. This division was exposed most destructively in the resignation of over 60 MPs from the front bench and a vote of no confidence by the Parliamentary Labour Party in the leader which took place immediately after the EU Referendum in June 2016. This attempt to force him out failed. Corbyn refused to go and thus a leadership challenge followed in which Owen Smith, although claiming the support of the vast majority of the parliamentary party, went down to defeat by 62% to 38%.
Since then, an uneasy peace has settled over the party in parliament, but divisions are not far beneath the surface and have emerged over the party’s response to Brexit, albeit without the same degree of publicly expressed rancour. Labour has started to shape a more directed response to the government on Brexit, steered by Keir Starmer, which has met with some success in pressing the government to reveal its plans, but Labour’s somewhat nuanced position seems to be hiding some deeper divisions, some of these between the PLP and party leaders (in reported tensions between Starmer and the Shadow Chancellor John McDonnell for instance), but also between MPs representing Remain supporting, cosmopolitan constituencies and those in Leave supporting ones.
This exposes a further important division, thirdly, which is the dislocation between the party generally and substantial parts of its ‘traditional’ working class support, especially in the North of England. Labour MPs were overwhelmingly Remain supporters during the referendum (just ten MPs out of 232 supported the Leave campaign), and so were most party supporters, but many of its so-called ‘traditional’ heartlands voted to overwhelmingly leave: although more than two thirds of party supporters voted Remain, seven out of ten Labour held seats voted Leave. Thus, contributions to parliamentary debates indicate that whilst most Labour MPs are inclined to take a Soft Brexit position, emphasising the importance of access to the single market in particular and clarity and reassurance for key businesses and employers, some Remain-supporting Labour MPs have in response begun to adjust their position. Ending free movement for them has become, post-Brexit, a ‘red line’and despite ‘proven economic benefits’ Steven Kinnock argued in a recent Fabian publication that it ‘is not socially and politically sustainable’. Failure to address it, wrote Rachel Reeves in the same publication, would be tantamount to ‘holding the voters in contempt’ However, at the same time key party leadership figures have argued a different line. Diane Abbot, for instance, in a November 26 interview in The Guardian argued that Labour needs to hold its nerve and maintain its support for free movement and defend immigration, reflecting views expressed by Corbyn himself that immigration is not in itself the issue so much as the resources communities have to cope with it. 
The trick that the Labour Party has to perform is to hold on to its old heartlands in the face of the challenges of Brexit, whilst seeking to build new constituencies of support. Corbyn seems to have made great strides in the latter. His leadership has clearly galvanised a large number of people and membership now stands at over 500,000 (it was 200,000 in 2015) bucking the general trend of decline in party membership across western Europe. This might indicate it seems a strength of appeal in leadership that many political parties lack. However, polls have suggested his appeal amongst the electorate is low and, furthermore, his approach has also raised questions about Labour’s function and focus. Is it an electoral party that seeks office through maximising votes, or is it a mass membership movement that seeks to mobilise opposition to the existing political consensus? A successful political party needs in some sense to be both but in a political system which is heavily centred on the sovereignty of parliament and is likely to get more so in some respects (because of leaving the EU), it is difficult to see how a genuine political breakthrough can be made without control of the parliamentary arena.
Another party in desperate need of a breakthrough is the Liberal Democrats. The first challenge the party faces is their weak parliamentary position and, thus, relatively low levels of influence. They were almost destroyed as a parliamentary force at the 2015 general election. They lost large number of voters, not least because having been part of the Coalition government with the Conservatives from 2010-15, the party could no longer rely on being a repository of protest votes. However, they gained no reward from elsewhere either, least of all their coalition partners. Indeed, they lost all 15 seats in their South West ‘heartland’, almost all of them to the Conservatives who ruthlessly targeted their seats. Overall, the result of that election was catastrophic, being reduced from a total of 57 MPs to just eight. Despite being the most Euro-enthusiastic party of all, and not long out of government, the Liberal Democrats were, due to their much diminished status, largely absent from the referendum campaign, and there were a distinct lack of significant roles for the party leader, Tim Farron, in key debates or on Remain platforms.
However, in the post-referendum landscape, their clear pro-European position has presented them with an opportunity, especially in the face of division or lack of clarity coming from the two main parties. They have cultivated and emphasised this pro-European voice in Parliament and their decision to oppose the (amended) Opposition Day motion in Parliament on 7th December which set a date for triggering Article 50 has set them apart as taking a strong anti-Brexit, or at least anti-Hard Brexit line on which it shares common ground with the Greens, Nationalists and a small number of Labour MPs. They have also sought to emphasise democratic credentials by developing this into a campaign for a further referendum on the outcome of negotiations. This is a distinctive line of argument taken by the remaining Liberal Democrats and their leader, Tim Farron, underlining their emergence as a clear, pro-Remain voice in the current political landscape. This appears to be attracting significant new membership (the party currently claims around 80,000 members) and growing support which has culminated in a stunning by-election success at the Richmond Park by-election on 1st December. Thus although severed at the head in 2015, the Liberal Democrats appear to be growing back at the roots.
UKIP was founded for the express purpose of agitating for, and winning, a referendum on membership of the European Union, and its unity of purpose in this respect at least was not in doubt. Despite only having one MP, UKIP has, in terms of setting the agenda, framing the debate and achieving political goals, been just about the most successful and effective political party of recent times. Both the staging and the outcome of the referendum represents the fulfilment of its founding purpose, which is something not all parties can claim, and underlines the perceived and real threat they have posed to both main parties. It is therefore an unequivocal success for UKIP as party and its members and leaders could be forgiven for basking in its success.
Leadership has clearly been vital to UKIP’s success. The achievement of its goal is in no small measure down to the skill and astuteness of Nigel Farage as a political operator and communicator. The pressure that the party’s success under his leadership has put on the main parties is what led to the promise of a referendum in the first place and the sharpening of the divide between Labour and its once taken-for-granted Northern heartlands. What he and UKIP have successfully done is, first, frame the impacts of the financial crisis as a problem of immigration and, second, linked the question of immigration to the European Union. Europe had for a long time been low down on the priorities of voters, but immigration and the economy were both high. To link all of these together in a way that exploited the political and economic fallout for the purposes of achieving a specific long-held ambition was a skilful piece of political campaigning
At the same time, despite their low parliamentary representation they attracted almost four million votes (12.6%) at the last election which has put them in a strong position electorally, too. They were remarkably consistent in their level of support across the country (except for London) meaning that overall it achieved 120 second places: 44 to Labour and 75 to the Conservatives (the other being the Speaker’s seat). At the same time, the collapse of the Liberal Democrat vote, particularly in the South West of England means that it is UKIP which arguably provides the most potent threat to the established parties, competing with Labour in much of the North, and the Conservatives in much of the South.
And yet, despite – or perhaps because of – this success, UKIP finds itself at a crossroads and a moment of introspection. Farage’s leadership is arguably what held the party together and stepping down leaves a gap that could be hard to fill. The infighting (literally in the case of two MEPs: leadership hopeful Steven Woolfe and Mike Hookem) and squabbling that followed the referendum and the debacle of Diane James’ short-lived leadership exposed this to a great extent. Indeed, even the Referendum itself exposed divisions in the party over the campaign, which may contain some clues about the lines of debate opening up as to its future as a political party. The more optimistic, relatively liberal side, represented by people like Douglas Carswell (the party’s only MP) and Suzanne Evans were aligned with the mainstream Vote Leave campaign, whilst Nigel Farage represented a populist, more explicitly anti-immigration campaign through Leave.EU, including the notorious ‘Breaking Point’ poster. Paul Nuttall’s election as leader provides UKIP with an opportunity to find a new, post-Brexit path. In his acceptance speech, he set UKIP the aim of replacing Labour as a patriotic working class voice. It remains to be seen if he can pull this off, but Labour MP Frank Field described his election as a ‘game changer’ for Labour.
Scottish National Party
Sixty-two per cent of Scotland’s voters supported Remain in the referendum which has provided opportunities for the Scottish National Party to further its campaign for independence. The party are in a strong position to do so and this is down to a number of factors. Firstly, strong, effective leadership which was on display in the immediate aftermath of the referendum. In contrast to other politicians who appeared in a state of shock at the result (including some of the winners), Sturgeon decisively pressed Scotland’s case. This is combined with the party’s straightforward clarity of purpose on the issue of independence, its large, motivated membership and its stunning electoral success in 2015 (when it gained 56 out of 59 Scottish seats). Thus its parliamentary position as the third largest party, which gives it rights in terms of asking questions, organising debates and populating committees, has enabled it to bring its own distinctive arguments to the Brexit debate. It has enabled it to press for a central role for the devolved administrations in negotiations as well as to push another constitutional dimension to the debate in the form of the argument that Brexit requires consent from Holyrood.Ultimately, much of this should be interpreted through the prism of the SNP’s campaign for independence, which underpins arguments that Scottish voters are sovereign and the vote for Remain needs to be ‘respected’. 
Although the huge difference in support for European Union membership in Scotland might appear to make another referendum on independence inevitable, it is notable that the party has been reticent about committing to this and a key question for the SNP is the extent to which Scottish voters would be willing to sacrifice a 300-year-old union with England and Wales for a European one. The SNP, in short are in a delicate position between the electorate and its membership and so the ‘threat’ of a second referendum is a weapon that has to be handled carefully. Support for independence does not seem to have grown dramatically, if at all, since the referendum, and the party will not want to initiate one if it is unlikely to win. Furthermore, polling suggests that most Scots would prefer not to have a second referendum for now at least. At the same time, however, those who identify as SNP voters are overwhelmingly in favour of independence and need to be kept happy too. So far, the SNP has proved adept at maintaining the balance between these two and continuing to get the balance right is likely deliver continued and sustainable success for the SNP.
Brexit and the aftermath of the referendum presents a number of challenges threats and opportunities for the political parties and how they respond to them may have a significant impact on the party system and its configuration for some time to come. In order to maintain its unity, the Conservative Party leadership faces the significant challenge of overcoming the divisions between supporters of ‘Hard’ and ‘Soft’ variations of Brexit, which appear to be increasingly entrenched, whilst at the same time providing a positive way forward for negotiating a settlement with the European Union which satisfies both sides. Labour, meanwhile, needs to find ways of bridging significant gaps between its MPs, its leaders, its members and its voters and faces the difficulty of maintaining a coherent response to Brexit whilst seeking to rebuild a potential election winning coalition. For both main parties, these divisions are reflected in their responses to Brexit which are strongly influenced by party management concerns. The Conservative leadership retains an air of ambiguity and secrecy so as not to antagonise the fragile relations between ‘hard’ and ‘soft’ Brexiters. The Labour Party, although ostensibly more sympathetic to ‘soft Brexit’ takes a somewhat nuanced position which masks the divided response the party has to it. Should they fail, however, to meet these challenges, other parties will be waiting to exploit the opportunities it offers them. The relative strength of UKIP as a voice for hard Brexit under their new leadership and their capacity to attract votes from Labour and the Conservatives is likely to have an important effect on how those parties’ overall positions develop. The same applies on the other side of the issue. The Liberal Democrats are emerging as a clear, pro-Remain voice in the current political situation and their recent success in Richmond Park has opened questions as to whether Conservatives are under threat from pro-European voters if they continue to take a relatively ‘Hard Brexit’ position. The SNP are also unequivocally pro-EU as a party and, given Scotland voted to Remain by a substantial margin, have carved out a clear role to defend Scotland’s interests, seek to influence the process and possibly use it to leverage further support for independence.
