We have indeed heard from business a very clear message about the importance of frictionless borders, which is precisely why the proposal that the United Kingdom has put forward to the European Union is based on that concept of frictionless borders. The free trade area that we have put forward is precisely in that frame. My right hon. and learned Friend talks about remaining in the single market and the customs union. I do not believe that that is right for the future of the United Kingdom, because I do not believe that doing those things would deliver on the vote of the British people. There are various things that underpinned the vote. An end to free movement was crucial among those, and remaining in the customs union does not enable us to have an independent trade policy. I believe it is important that we do have an independent trade policy once we have left the European Union. We are negotiating the basis of our future trading relationship, but it is based on the concept of a free trade area and precisely the point that he makes about being able to move goods seamlessly across the border.
