Duties of Customs

Is my hon. Friend aware—he probably is not, because I have yet not told him—that a couple of weeks ago I asked the Secretary of State for Exiting the EU whether a deal like the Canada’s free trade agreement with the EU would be a good deal for Britain. He said, “No, because it would not be as good a deal as the customs union. It would leave us worse off.” I therefore cannot see how one can possibly argue that one should automatically discount staying in the customs union.
