The right hon. Lady has asked me on a number of occasions about a customs union, and I have made my view on a customs union very clear. A number of alternative ways forward in relation to a deal have been suggested over time in this House, but there are a number of questions that Members need to ask themselves. When she talks about a customs union, what rules would she see us abiding by? Would it involve abiding by state aid rules? In some of the proposals, there is a real question whether free movement would continue to be abided by. I stood on a manifesto that made reference to a customs union because I and the Labour party both believed we should be able to have an independent trade policy. It continues to be my view that we should have an independent trade policy in the future.
