So the EU have chosen Michel Barnier to lead their negotiations, whose politics further reinforce the notion that access to the free market will require accepting freedom of movement. This may at first seem like a bad thing, but personally I'm of a view that it will make things easier for us in some ways. Essentially it eliminates a whole facet of the debate as although access would be nice it isn't imperative, and certainly not worth the cost. So rather than getting bogged down in that debate it will be straight into discussions on tariffs etc. and what level of mutually beneficial co-operation. Obviously this assumes that our negotiators don't go in with an "access at all costs" mentality, but with everything that has been said by May et.al. so far it doesn't appear to be the case. Plus it would be political suicide for the Conservatives to sign up to freedom of movement given the level of opposition and repeated assertions that they "heard the message". Now whether or not this would send the European various factions into serious conflict remains to be seen, but I would expect some degree of shenanigans.
Bearing this in mind it would be safe to say my basic position is out of the single market, leaving us free to set our own tariffs with other nations. However, once you get beyond that about the only thing I know for certain is that I want the UK to honour and further it's commitments to "Big Science" e.g. CERN. How that then plays out in terms of scientists / engineers moving between either UK and EU or vice versa is obviously a discussion point. Certainly it would be nice if both sides could agree that it is important and find a sensible solution.
Anyway I'm curious as to what other people want to see from the negotiations. However, I'd like to set one basic ground rule in that we try to avoid getting bogged down in discussions about likelihood. "All In" or "All Out" may appear to be more likely than "In / Out" when it comes to the single market and freedom of movement, but until this process starts we really have no idea beyond posturing by politicians.
