It is being mooted by the government to announce that any country leaving the EU will be almost guaranteed a free trade agreement with the UK. Ursula VD will not like that.

Maybe the UK could eventually start an organisation of countries that do mutually free trade with each other and nothing else, no centrally organised laws to apply all over the membership, no single currency applicable to all the membership and no gathering of membership money from any country. It would simply be a free trade organisation.
