I will conclude if I may. I have already taken longer than I said, so please forgive me. Let me just touch on this question: how we can get this whole debate into the grown up world and accept the reality that exists in a globalised economy. What do we mean by international trade agreements? What is beneficial to a country such as ours to give us the best base for future prosperity in the modern world? Frankly, at times, some of the debate has taken on an unreal quality. I will not follow the hon. Member for Nottingham East, my collaborator in this new clause, because he gave a very carefully researched and very clear description of what actually is involved in trading arrangements. The first simple political point I will make is that, at the moment, we have absolutely unfettered access, by way of regulatory barriers, customs and so on, to the biggest and most open free-trade system in the world. Nowhere else has rivalled it. Mercosur failed because it did not have the institutions such as the Court or the Commission; the North American Free Trade Agreement-NAFTA-is collapsing; and the Americans have pulled out of the Trans-Pacific Partnership. Everybody wants these deals, but only 28 European nation states have succeeded in getting such an open one. Of course the hon. Member for Vauxhall and others have argued strongly that we voted to leave that. Anything new that we put in by way of tariff barriers, customs barriers or regulatory barriers is bound to damage our position compared with where we are now. That is why we should minimise all those things as far as we can. It is no good developing some fantasy that we are going to reach an agreement that puts up new barriers to trade-that we are going to get protectionist towards the rest of Europe, while being ultimate free traders towards the rest of the world-without damaging ourselves. Both sides exaggerate, which is pretty typical of most political arguments that take place in any democracy. Once people start putting mad figures on everything, they can get carried away.
