Before the referendum result was declared, most MPs had opposed Brexit. Some of them will now feel it is their duty to give effect to the majority decision of the voters. But since it will be at least three months and probably a lot longer before the new prime minister is in a position to trigger article 50, my own view is that the government will require, at the very least, a majority vote in the House of Commons before proceeding.

One might have argued that a kamikaze prime minister could have triggered article 50 immediately after the referendum result was declared, using his prerogative powers. Those powers are used to sign treaties but not, I would argue, to put them into effect in the UK. In any event, there is a growing constitutional convention that prerogative powers are subject to parliamentary approval, as we saw with the Commons vote in August 2013 against air strikes on Syria.
