My Lords, my perspective is that of a former negotiator. I do not think that a serious parliamentary procedure of the kind set out in the amendment for the approval of a mandate and the approval of the outcome of a negotiation damages one’s negotiating stance or limits one’s flexibility. I do not believe that at all. Having negotiated against Americans, I know that it greatly strengthens their hand to be able to say, “Here is the proof that I cannot give you what you want, because Congress would turn it down”. At the end of the day, when Congress turns one down—and it does—that is a very serious and effective deterrent to those disagreeing with the Americans in a negotiation. Speaking against unilateral disarmament in 1957, Aneurin Bevan talked of the dangers of sending the Foreign Secretary naked into the conference room. If we do not accept the amendment in the name of the noble Lord, Lord Stevenson of Balmacara, we will weaken the hand of British negotiators in the future.

My Lords, I will intervene very briefly. The proposers of this amendment put forward their arguments so admirably that there is little more to say, particularly the noble Lord, Lord Hannay, who compared the role envisaged for this Parliament with the roles of other parliaments. As we all know, one of the key arguments in the referendum campaign was about taking back control. Here is an absolute instance of where Parliament ought to take on greater powers if it is to take back control over an important area of British policy. The other thing is that a great deal has been made by the Government, the Secretary of State for International Trade and the Prime Minister about the centrality of being able to do trade deals. The argument is put forward that one of the great reasons for being outside the EU is that it gives us the ability to do trade deals. They are going to be a central part of government activity once we have left the European Union. For those two reasons, it seems to me that the Minister will have to put forward some very strong arguments indeed if she is to convince me and perhaps some others that it is right for the Government to ignore the principle inherent in this amendment.
