I suppose they're using the ancient tactic of presenting proposals which they know are unacceptable to the EU. Then they can say the EU are inflexible and intransigent, and the devout Brexiters will believe this. True faith.
The astonishing thing is that this is so blatant that no one who is not completely intellectually challenged can see it. I don't think every Brexiteer is completely thick, but the intransigence of many of the leave camp seems to have left them an easy prey to any devious tactic that Johnson and his cronies employ.
I've previously referred to the astonishing brass-neck of the leaders of the Brexit campaign, which leads them to blithely try to use any tactic to achieve their goal, no matter how weak their position must now seem to any objective analysis (of course, they're counting on the weakness and division of the opposition). I'm sure Johnson doesn't fully believe in the political stance he is taking, nor Stephen Barclay. Perhaps Rees-Mogg might just, lost in his dreams of Britain's glory days, and cosseted from any financial hardship while he, no doubt, has his anonymous accountants looking after his overseas investments.
As for that obnoxious windbag Geoffrey Cox, the Attorney General - he wouldn't know what the truth was if it jumped up and bit him on his fat arse.
