Much like what happened when the original vote from the seventies was overturned then. It amuses me when Leavers say democracy should be respected following the referendum, when there had been politicians, business people and men and women working in the media who had been banging on about having another vote on Europe for the last three or four decades - Nigel Farage even said that he would campaign for another vote if the outcome in 2016 had been 52/48 in favour of remain.
