The final step. Why the leader of the Conservative party does not automatically become Prime Minister

The final step. Why the leader of the Conservative party does not automatically become Prime Minister

Professor Brian Cox was once asked to explain string theory in a sentence. His answer: “It’s probably not true.” The same one sentence explanation could be used to explain the theory that the next Conservative leader might not become Prime Minister. But since it’s being talked about quite a bit, let’s have a look at why.

The current Parliament was elected at a general election held on 8 June 2017. It resulted in a hung Parliament. It is forgotten now, because Theresa May held office both before and after that election, just how precarious her grip on power was. She faced two challenges simultaneously: retaining control of her own party and retaining control of Parliament.  

Theresa May stayed in office as Prime Minister for two reasons. First, as the incumbent, she had the right to try to form a government first, just as Ted Heath had in 1974 and Gordon Brown had in 2010. And secondly, because whether or not she was going to be successful, someone had to fill the role until the successful contender had emerged and that responsibility falls to the incumbent.

During the intervening period, there was some genuine doubt about whether the negotiations with the DUP would reach a successful outcome. Jeremy Corbyn was demanding the right to get the keys of Number 10. It was not until 26 June 2017 that the Conservative party reached agreement with the DUP on a supply and confidence arrangement.  

The last two years have not been kind to the Conservative party. Brexit has acted as a centrifuge on it, its forces pinning its MPs and leaving them feeling dizzy and sick. It has already seen four MPs break away from its Remain wing, further weakening its already-etiolated control of Parliament. Another of their number has just been ejected from Parliament by recall, meaning that a by-election is pending. The Conservatives’ effective majority, with DUP support, is currently just two.

Many remaining Conservative MPs do not trouble to conceal their dismay at the prospect of no deal Brexit and Boris Johnson. Some, such as Ken Clarke and Dominic Grieve, have been making public or semi-public their intention to oppose him in the name of Brexit. The continuing complexities of his personal life and his reclusiveness will be doing nothing to deter them. Several of them are being threatened with deselection, giving them little to lose by going rogue.

To date, no one has ever gone broke betting on the Conservative Remainers failing to follow through. So it must remain by some way the likeliest outcome that most of them will go quietly, at least initially, deluding themselves that they should wait and see. You and I might wonder what they would be waiting to see, but they aren’t called wets for nothing.

Numbers are so tight, however, that even a handful might transform the calculation. Lyndon B Johnson reputedly said that the first rule of politics was knowing how to count. Let’s consider that first rule for a while. If Boris Johnson looks unlikely to be able to command the confidence of the House of Commons, what then?

Professor Cox would appreciate that a different first rule, Newton’s First Law of Motion, applies.  Unless and until something happens, the status quo continues. So Theresa May stays in office until she resigns or is ousted. The assumption is that she will speedily resign after the conclusion of the Conservative leadership election campaign. That assumption looks very open to question.

When she resigns, it is her duty (as well as that of other senior statesmen) to recommend to the Queen the person who she believes can be expected to command the confidence of the Commons. If that is not clear to her, she should not make such a recommendation. It is very questionable whether she should resign at all until things become clearer.

Obviously, this would be an extremely unstable equilibrium. Theresa May would have no visible means of support. At any point, she might face a Parliamentary vote of no confidence in her government.  This would presumably pass. We would then enter a period of 14 days to find a government that commanded the confidence of the Commons. Otherwise, a general election is automatically held.

Even after the passing of a vote of no confidence, Theresa May is not obliged to resign as Prime Minister and might well not. After James Callaghan was defeated in a vote of no confidence in 1979, the government continued in office for a further week before Parliament was dissolved. Theresa May might reasonably argue that she should stay in situ until it was clear that a fresh government was capable of being formed that might command the confidence of Parliament.

Political journalists, who have frankly been spoiled in recent years by the speed and variety of political developments, would love the chaos. The rest of us, not so much. Where it would go, goodness only knows. On the track record of recent years, nowhere very good.

In the end, however, Boris Johnson would probably be able to line up enough votes behind him at least to have a shot at proving that he could control a majority. With Labour having lost a more than a dozen MPs from its ranks since 2017, enough independents might abstain or prop him up to justify him being called to kiss hands to test his chances in Parliament, unless rather more Conservative MPs are prepared to take a stand than have already made themselves known – at least half a dozen, I think.  

Even if Boris Johnson tries and fails, a Prime Minister for a few days is still a Prime Minister. At least for betting purposes, anyway.

What might happen after that is still murkier. Perhaps Brian Cox could explain it in 11 dimensions for us. I’m all ears.
