Board games are always a good source of arguments. There seem to be as many views on how to play Monopoly as families. Some place all fines in the centre, to be collected by anyone who lands on Free Parking. Some don’t allow rents to be collected in Jail. Views differ on what is to be done with the properties of bankrupt players. It is important to establish the rules in advance if you want to avoid unseemly rows.
Parliamentary politics is often presented as a parlour game. It isn’t: but it has rules. Those rules recently changed in a small but critically important way. Most people haven’t properly thought through the implications of that rule change. Unseemly rows will ensue.
Let’s start with the basics. Government is formed by a Prime Minister who can command the confidence of the House of Commons. Where one party has an overall majority, the leader of that party will get the job pretty much automatically. Where there is a hung Parliament, there is some horse-trading to be done. Parties can form a formal coalition, as happened in 2010, or a minority government can be formed with a smaller party offering only supply and confidence for an agreed programme rather than ministers, as happened in 2017 when the DUP backed the Conservatives.
Such agreements, however, only operate in the sphere of politics. They are not legally binding. The Conservatives found out in 2012 that coalition partners can rat on the deal when the Lib Dems refused to agree to boundary changes. They found out earlier this year that support in a minority government can be just as flaky when the DUP opposed some measures in the budget.
The reason for the DUP’s unreliable behaviour is well-known. The government’s proposed backstop in the withdrawal agreement would change Northern Ireland’s status in a way that they regard as completely unacceptable. They are out for blood.
In times past, the defeat of the government on central measures like the budget would have led inevitably to its fall, the defeat itself demonstrating that the government no longer has the confidence of the House. The Fixed Term Parliaments Act 2011 changed all that though. There is now a formal mechanism for selecting governments and, still more importantly, a formal mechanism for getting rid of governments.
There are exactly three ways of getting rid of a government. The first is that a motion for a general election is agreed by at least two thirds of the whole House (that is what happened in 2017). The second is that a motion of no confidence is passed. The third is if the Prime Minister voluntarily resigns.
What this means is that the DUP can leave the government becalmed in the doldrums, with confidence but without supply. The government cannot call a general election unilaterally. If a vote of confidence is called, the DUP can cheerfully support them in that. Everything else, however, and the government is on its own. Block the Prime Minister’s deal? That goes without saying. Vote down the budget? Sure. Support Labour in a vote of censure against the Prime Minister? Naturally.
This leaves the government potentially paralysed. Unless it can find alternative support in other votes, the government will be in office but not in power until such time as it does what the DUP wants. Such alternative support will not be easily found or come cheap.
This gives the DUP outsized importance. In many ways they have more power than the ERG, which breaks the Conservative whip only at the risk of losing it, with all of the profound consequences that holds. Maybe the ERG might break away to set up Son Of UKIP but the Rubicon can only be crossed once. Till then, the ERG will need to display a veneer of loyalty to the Prime Minister.
If the DUP want shot of the Prime Minister – and they may – they have a technique to winkle her out of Number 10 without letting Labour in. It may have done Theresa May no practical good at all to have won her party vote of confidence if the only thing she can achieve in the House is to defeat votes of no confidence. If so, sooner or later she or her colleagues are going to need to change strategy or change the leader, or both. The fact that she is bomb-proof in her own party for a year would be an irrelevance.
So what does the government do next? For now, it is putting off the moment of decision. Unable to win the meaningful vote on its deal, it is temporising. There look to be only two ways out of this impasse. The first is to continue to temporise up to 29 March 2019 and hope that the nerves of some Labour MPs will be sufficiently worn that they will cave in and support the deal, with an acceptance that no deal might be the result. The second is to switch tactics and seek to build a cross-party alliance for a referendum, throwing the matter back to the public.
Neither looks appetising for Theresa May. Never one to make choices actively, she might well take the first route by default. Will her colleagues allow her to do so or will she find herself bypassed? We might well find out. Either way, the Conservative party looks set to break.
