And at least that blame (if it is right) can be spread a long way. More than half the voting public voted to leave the EU. That will spread that blame extremely thinly.
Also there is the matter of Barnier originally saying that he would only offer the UK the same terms as Canada, but then, apparently, withdrawing that option. Where does the blame for that lie? I would suggest that some of it lies with the BBC and the remain camp. They seem to have convinced the EU that, if the EU held its nerve, and didn't offer a good deal, then the referendum would be overturned. While we still had Theresa May that might have come true. But now it is the EU that is playing chicken and they haven't realised that the game has changed.
If we leave on WTO terms (called 'no deal' by some) then we are out, and negotiations can re-start in earnest, with the EU negotiating from a totally different position.
France look as if they want to scupper any deal, and insist that the EU must not give in on fisheries, hence the attempt to get an 80/20 split. If we leave on WTO terms then the UK regains full cotrol of our coastal waters, and France will be looking to increase from zero%. A totally different position.
I would like to see UK get a good deal, but still feel that " 'No deal' is better than a bad deal".
We will know within three weeks.
