Yes and no. I think they need a total redo, but the problem is that May has been such a poor negotiator that the EU will but scoff.
I happened to be in London when the Brexit initiative passed, and several Brits told me that they had voted for it just to make a statement, because they thought it wouldnt pass.
There should have been a plan in place before the vote. And in any case, a lot of the things they thought were voting against - such as Muslim accommodation and speech crime laws - were actually part of British law and the EU was not involved.
The feckless Brits cave again. Sick and tired of their arrogant snobbery. Let them suffer some more until the bubble bursts, which it will. Two men in England have brains. Farage and one other back bencher.
EU not involved in speech crime? Articles 11 and 13 prove otherwise.
