Yes, NotDavid, I think they do think they are going to get a free trade deal. What I don't understand is why they think that.
I mean, if the EU gives the UK a free trade deal, but not making them sign up to any other bits of the EU (freedom of movement for people, European Court of Human Rights, Health and Safety standards, to name but a few, what's to stop every other country doing the same.
We are back to the four freedoms - free movement of goods, service, people and capital - which must all be negotiated together. The UK doesn't want free movement of people or capital - they can't simply demand the other two.
