My hon. Friend makes an interesting point, but it seems to me that the difference between the two judgments is that the Supreme Court made it clear that in an irrevocable act, what was happening in its view was a fundamental change in our constitution, which is a different character of argument from what was made in the High Court judgment—and it seems to me conclusive. It means that the Supreme Court has ruled that, in its view, this is an irrevocable act.
In a sense, that is irrelevant to us, because we are a Parliament and not a group of lawyers. So we come next to the question of the democratic mandate. Is there
a democratic mandate requiring that, when article 50 is triggered, the result—whatever it may be; an acceptable deal or a non-acceptable deal—should be that this country leaves?
In that regard, I thought that my right hon. Friend the Member for Chesham and Amersham (Mrs Gillan) and one of two others who spoke in similar terms were right. In fact, I know they were right, because I am one of the guilty men. During the referendum campaign, I made it perfectly clear to the many audiences whom I addressed that, in my view—and this is part of the reason why I voted to remain—an inevitable consequence of leaving the EU would be leaving the single market, we would have to reassert our control of the borders that would be incompatible with the single market, we would seek to negotiate with the rest of the world, and therefore we would have to leave the customs union. I made it perfectly clear that we might find ourselves unable to negotiate a free trade agreement—because that takes two sides, and it is impossible for one side to guarantee what the other side will do—and that therefore we might have to fall back on the WTO, which I think would be greatly to the disadvantage of this country.
I made all that clear, so it seems to me, when it comes to the question of the democratic mandate, that the people who voted to leave were voting with their eyes wide open, knowing that the consequence might be our falling back on the WTO. I should add, to be fair, that the leave campaign—or, at least, the more responsible and sensible people in the leave campaign—made that perfectly clear as well. It seems to me that, both as a matter of legal fact and in the context of a democratic mandate, there is an extraordinarily strong argument for believing that when we vote tomorrow night we shall be taking an irrevocable step, which should not lead Parliament to be under any illusion that at a later date it can go back to remaining if it chooses, and if it does not like the deal.
The third and, I think, overwhelming point is this: in the end, what matters most is the fate of our country. All these arguments are just arguments, but the fate of our country is a real thing that affects the men and women living in it. The truth is that the negotiating hand that our Government have will largely determine whether, in the event, we secure a comprehensive free trade deal of the kind that the Prime Minister rightly seeks. I know of no fact more certain than that if the House were to suggest to our counterparties in the EU 27 that we might decide at a later date that, if the deal offered to us was bad enough, we would prefer to remain, they would offer us the worst deal they could think of. It would be an inevitable consequence of their wanting to keep us in—and, although I do not know exactly why, many of our EU 27 counterparties do want to keep us in—that they would best achieve that by offering the worst deal possible if they knew that Parliament might then vote to remain.
I therefore think that we in the House have a very solemn duty to make it abundantly clear—not just to the people in this country, but to the EU 27—that tomorrow night’s vote will be an irrevocable act. We must make it clear that we are taking a step from which we cannot go back; that if those countries want a proper deal that is in the mutual interest, they should offer it; and that if we do not get that deal we will leave,
because we have triggered article 50 and we will be out, and we will have to cope with the consequences thereafter. That makes tomorrow night’s vote one of the most important that we shall ever take in the House, and I take it with some doubt and hesitation, but I take it because I believe that, ultimately, the will of the people has been expressed.
