Boris to the Mail on May’s customs partnership:

“If you have the new customs partnership, you have a crazy system whereby you end up collecting the tariffs on behalf of the EU at the U.K. frontier. If the EU decides to impose punitive tariffs on something the U.K. wants to bring in cheaply, there’s nothing you can do. That’s not taking back control of your trade policy, it’s not taking back control of your laws, it’s not taking back control of your borders and it’s actually not taking back control of your money either, because tariffs would get paid centrally back to Brussels.”
