In spite of the public posturing, I reckon that people are doing a lot of talking behind the scenes about how to wriggle out of Brexit.
There will be scapegoats - those who are not able to save their arses and their faces at the same time - the ones regarded as more expendable.
My greatest concern is that as the politicians fudge, a new champion of the extreme right will emerge (Farage?). He would probably trigger Article 50 but the new isolation wouldn't be the Promised Land, it would more likely be a slow descent into pre-war Germany.
