I thank my right hon. and learned Friend for his view on this. He sort of expressed it in an amendment that he tabled late last night, so I only saw it this morning. I have not really had a lot of time—[Interruption.] Well, this is an interesting demonstration of the Labour party’s perception of how easy it is to make constitutional law on the fly. Its own voters will come to a view on that.
Let me say this with respect to my right hon. and learned Friend’s proposed amendment—as he knows, I am always open to have a conversation with him on this although he seems to have fallen foul of my telephone security system—I always want to keep three principles in mind. First, we must never do anything that undermines
the Government’s negotiating position, or encourages delays in the negotiations. That is very, very important. Secondly, we cannot change the fundamental constitutional structure, which makes the Government responsible for international relations and international treaties.
