Everything going pear-shaped in the forthcoming negotiations could be the game-changer. We may not need another referendum in order to prevent this impending disaster. I'm convinced in any case that another referendum would give the same result, as millions of voters would be persuaded, wrongly, that calling it was an affront to democracy. That would be an extremely easy case to make by leavers, much easier than the case the remain side would be able to make. I can just see the sloganising now. In fact, I think I'll put myself up for the job of slogan-writer for the leave side. Money for old rope.
