How did leave voters expect the EU to act.
Did you expect them to give the UK a favorable deal that might encourage other major players to leave?
No. Not at all.
In 2016, I (albeit naively) expected both sides of the argument in the UK to work together towards negotiating with the EU. We didn't get that and I should have known better. We had 3 years of petty squabbling and a Labour party (conversely led by a bloke who was for Brexit) which ultimately went against the wishes of a lot of its voters on Brexit and hence suffered a huge loss in the last election.
We then got COVID which further compounded the issue and showed up just how pathetic all the in-fighting was.
The EU want a deal too and there has to be compromises on both sides, which both sides fully accept. It's all a face-saving exercise from all involved. If I could turn back time and have the vote again, I'd vote remain, but not because the EU is great, but because of the mess Brexit has ended up as for a variety of reasons - most of it self-inflicted, some of it from the EU also playing equally as daft as us, and a lot of it because of the totally inept government we have.
