Benjamin Martill and Leo von Bülow-Quirk argue there’s still a way to reach agreement on a Brexit deal—but it’ll require Parliament to work in a whole new way.
Here we go again. On Tuesday the ‘mother of all parliaments’ inflicted the mother of all defeats on the government, rejecting Theresa May’s painstakingly negotiated withdrawal agreement by a huge majority of 230. Not since the 1920s has a sitting government been so roundly defeated in the Commons, and never on the most pressing matter affecting the country. The opposition then tabled a vote of no confidence, largely because to do otherwise would have been too reputationally damaging given the circumstances, not because it expected to win. Theresa May’s success in maintaining her position as prime minister has amplified the looming possibility of a no deal Brexit by 29 March. How did we get here?
In our view, it is down to the institutions and political culture of Westminster, which venerate adversarialism over consensus-building and tub-thumping rhetoric over truth-seeking or problem solving. Historically, it has been said, this system produces strong government. But it also has a critical weakness, which has been spectacularly exposed by the Brexit debate. The UK’s majoritarian system—which requires parties to link together diverse constituencies with differing viewpoints, and in which government-forming is a zero-sum game—means Westminster lacks the incentives and political culture to build compromise. Yet such compromise is critical for an issue as complex and strategically significant as Brexit.
May’s premiership has epitomised  this deficiency. On assuming the reins of government in 2016, she foreclosed any discussion of a cross-party commission or meaningful regional representation, and swiftly adopted the rhetoric of the hardest Brexiteers, which precluded meaningful discussion with other stakeholders. She was probably not surprised that appeals to the opposition to support her Brexit deal were swiftly rebuffed.
Yet despite her deal’s resounding defeat, May will remain prime minister, at least for now. Her right-wing critics played their hand too soon  by calling an internal confidence vote in December of last year, squandering their opportunity to initiate an internal change of leadership for another year. May also won the general no confidence vote tabled by Labour, in part because her critics in her own party dislike the idea of a general election and a Corbyn government more than they dislike her leadership.
Three Ways Forward
Now that May has affirmed her power, what options has she left? We identify three potential avenues, each of which is subject to severe political constraints.
First, the prime minister could stand behind her existing agreement and attempt to reintroduce it to Parliament with minimal modifications (e.g. renewed assurances from Brussels that the backstop is indeed intended to be temporary). This would not create any problems for Brussels, since it has already signed on to the deal as it stands. And, having ‘virtue-signalled’ their principles in yesterday’s vote, MPs could credibly back it in a second vote, using reassurances from Brussels and the increasing probability of no deal as justification. But this is a long shot, and the scale of the government’s defeat would require changes of heart from perhaps too large a number of MPs. Moreover, if May’s opponents on both sides stick to their guns, the end result is the worst possible outcome for all as Britain falls off the proverbial cliff-edge.
Second, May could attempt to gain the support of rebels within her own party, and her partners in the Democratic Unionist Party, who want to return to the negotiating table and the pursuit of greater concessions from the EU. Unsurprisingly, many of these MPs believe that the UK maintains the upper hand, that EU unity is a façade, and that Britain will win the game of chicken it seems to be playing with the EU if only it doubles down on the threat of no deal. The problem is that this position is based on a misreading of Britain’s bargaining power  and the EU’s willingness to re-enter negotiations. The EU will be damaged by no deal, but not as much as will the UK. More important, if the EU accedes to Britain’s demands, it re-opens the moral hazard question that threatens to upend the entire project. Ironically, for the EU, no deal really is better than a bad deal.
Third, May could make overtures to the opposition, seeking to pass her deal with the support of Labour MPs, whose views are, ironically, closer to her own than are those of her pro-Brexit Conservative colleagues. May did indeed strike a rare contrite tone in her speech immediately following her deal’s defeat, potentially signalling willingness to compromise. A workable cross-party compromise might exist in the form of customs union membership, which forms the core of the opposition’s own Brexit demands. Renegotiating might require an extension of Article 50, but this may be more acceptable to the EU, if the desired outcome is a softer Brexit.
The third option is the most workable of these and provides a route out of the Brexit impasse. But it requires all political parties to adopt a spirit of compromise which, until now, they’ve been unable to display. It is not the EU’s position that would prevent such a workable compromise. Rather it is the aforementioned adversarial structure of British politics. The greatest stumbling block is Labour’s interest in collapsing the government in order to seek a general election and return to power. Corbyn has made it clear this is his strategy and the unity of Labour MPs in Tuesday’s vote suggests his party is willing to follow him. Whether a failed no confidence vote would change this calculation remains to be seen. But there is also the question of whether moderate Conservatives, who would in theory back a softer deal along the lines proposed by Labour, would admit as much for fear of bolstering Corbyn’s credibility and ushering in a Labour government.
Two Ways Out
How do we escape from this bind, in which complex political realities are reduced to binary political allegiances and interests?
All of the options are problematic, but there are a couple of ways the government could strengthen the chances of the agreement passing in the near future.
First, May could offer Labour a post-Brexit general election as the price for supporting her deal. This would give May what she desires most (passage of the agreement) and Labour their professed goal, while assembling a potentially more-legitimate cross-party majority for her Brexit deal. May herself has signalled that she is not seeking a post-Brexit premiership, so the price may be worth it for her, politically speaking. It also might not be as selfless as it sounds, since the outcome of any such election would be uncertain, and since the Tories may even enter on a high having enacted the agreement. Certainly an offer along these lines would force Labour to be honest about how committed they are to achieving a soft Brexit versus collapsing the government.
Second, having worked across party lines to generate a variety of workable Brexit scenarios, the government could consider holding a referendum in which all these variants of leaving the EU are on the table under a single transferable vote system. This would confer democratic legitimacy on the terms on which Britain leaves the EU without overturning the verdict of the 2016 referendum.
These solutions are not perfect, but they do offer a way to overcome the institutional and partisan deadlocks, which are blocking a potentially workable consensus and risking a catastrophic no deal scenario. Will Westminster rise to the challenge? They say you can’t teach an old dog new tricks. But perhaps Brexit can.
