United Kingdom

Someone has to change their mind - I'd say the closest British proposals that could be melded into something that could get a majority and the EU would agree to are, ironically, May's and Corbyn's. Some sort of customs union without freedom of movement.

But both, especially May, don't want to have a 'grand coalition' to solve this, because it would tear apart their parties to cooperate with the other (May is in more danger because the anti-EU feeling in a large wing of the Tories runs deep); and they know they'd then face a rejuvenated UKIP that picks up defectors from the old party/parties.

Yes, still possible to end up with 'no deal' and an exit at the end of March.
