Dr Julian Lewis: Does the Prime Minister recall that, when we held the vote in September last year on the European Union Referendum Bill, not a single Conservative, and only one Labour Member, voted against it, so is it not a bit late now for people to talk about blocking the implementation of the result just because they disagree with it? Finally – it ​is always good to end on a positive note – would the Prime Minister care to bring in the vote on the Trident successor submarines before he leaves office?

[The Prime Minister: It is very clear: when it comes to numbers, my right hon. Friend wants four submarines and one referendum – I have got the message very clearly. He makes a good point, which is that when the House voted on the referendum, it voted by a margin of six to one to hold that referendum. We will obviously be coming forward with our plan for all the other decisions that can be made during the remainder of this parliamentary Session, and I would hope that it would include the one he mentions.]
