The answer to that question is ‘many’. I've had many discussions already. We'll continue to hold those discussions and the Member will know that I’ve outlined what I think will be needed to continue with an internal single market within the UK itself: namely that there is a rules-based system, secondly, that those rules are agreed by all four Governments, and, thirdly, that there is an independent adjudicator—a trade court, if you like—that will police those rules. If all those requirements are satisfied, then I believe the single market can be robust.
