One final comment - or rather question - arising from that remarkable documentary.
It was absolutely clear throughout the process that the EU side were stunned by the incompetence, weakness, unpreparedness, naivety and sheer stupidity of the British team led by Oliver Robbins.
Is it possible that that he was selected by Mark Sedwill not because he was the best that the civil service had to offer, but the worst? A head negotiator warranted to screw it up and produce a treaty advantageous to the EU? A humiliation of a treaty equal to Versailles?
Meanwhile, the Brexit Party scores 34% of YouGov's latest poll - more than Labour and the LibDems combined. And that's before May does a deal with Corbyn.
And can anyone explain why my London ballot paper has on it 11 independents who can each afford a £5,000 deposit?
