Probably irrelevant what kind of Brexit May or the Government decide upon. Surely it is the rest of the EU that will decide - and they even have to have total unanimity- any of the EU members can VETO the decision. The EU has already made it clear : no negotiations prior to article 50- then the rules are clear - once the country have called article 50, it will NOT have any say in the negotiations. Klar! I'm amazed people are now all surprised about this- as this was not clear since 1973- and say the EU is being 'vindictive and wants to punish' the UK, etc.
