Not really, I doubt there was ever really going to be a deal as the EU’s stance was not realistic. The last PM really made a mess of things but then she was never really a Brexiteer so not really surprising.
Funny thing is the vote for Brexit would never have been won, if the EU had been more on the ball and allowed countries to manage their own borders so they could restrict who could comes into the country. It’s that problem that highlighted issues with the EU at least for myself and I’m sure for others. Once highlighted you tend to look more closely at other related situations.
The problems with immigrants that the world is experiencing is probably why nationalism is on the increase.
