To pinch minty's catchword 'YIKES!!!'
Seriously, I don't think it can be done. 'Leavers' had a referendum, they voted, they won and they left the government to get on with it. You know, that old-fashioned belief in Democracy that we grew up with.
Tempting for such as May and the Remainers, but the polls (inaccurate as they are) are already showing that those who voted UKIP originally, in order to force a referendum (I'm one of them) and then voted Tory to ensure the Brexit they were promised would transpire, are flooding back to UKIP - which could, at this rate reach 25% of the vote before many moons are out. (not my figures, read it somewhere but seems likely).
