After more than three hours of debate, a great deal of what needed to be said on either side has been said, and I do not intend to bore the House by repeating it. Like my right hon. and learned Friend the Member for Rushcliffe (Mr Clarke), I voted to remain; unlike him, I voted to promote the referendum and indeed played some part in bringing the Conservative party to the point of committing to a referendum. I shall therefore obviously vote tonight in favour of triggering article 50 in line with the outcome of that referendum. I shall also vote in the succeeding week against each and every attempt through amendments of whatever kind to bind the Government in any way—administratively or legally—because the Government must have the ability to negotiate flexibly and in the national interest.
In the brief minutes allowed, I would like to add one point that I do not think has so far come out of the debate: what we are doing if, as I suspect, we vote tomorrow night to trigger article 50. There has been some suggestion in some speeches that, somehow or other, this vote is not irrevocable or final, and that there will come a time when Parliament can decide whether it likes the deal that the Government have negotiated or whether it prefers instead to go back to the position of remaining in the EU. That is clearly contrary to what the Prime Minister set out in her speech, when she made it perfectly clear that, in her view, what Parliament will then be deciding is whether to accept the deal or not to accept it, in which case we will have to fall back on the WTO and other such arrangements because we will in any case leave.
I want to make it clear why I think the Prime Minister was right about that from three points of view. The first is the question of legal fact. None of us in this House is qualified to make a judgment about the law in that respect, but we have a piece of luck, which is that the Supreme Court has made a judgment on that. In the judgment of the High Court—a rather unusual High Court as it was composed—it was not totally clear, but in the Supreme Court judgment it was totally clear that the presumption of the minority as well as the majority was that this was an irrevocable act. The whole foundation of the legal case was that.
