There's an interesting point turning up in BTL discussions at the graun from ostensibly european posters, which is there in different ways but is essentially this...
When you listen to our side, there still seems to be the idea that the only thing that would make us cede anything in withdrawal negotiations is the kind of trade deal we want. We don't get that this is entirely another question so far as the rest of the EU are concerned.Incredibly the Brits do not understand that the 'final deal' is just a withdrawal agreement - it is about sorting out the legal technicalities of 100% disentangling the UK from the EU. It is NOT about the future EU27-UK relationship. Trade negotiations will only start AFTER 30 March 2019 = after the UK becomes a third country in relation to the EU.
