Surely, now the implications of Brexit have now becom obvious, it would be the democratic thing to ask the minority of the population to ask to vote again thereby not only giving them a chance to decide whether they had made a mistake, but possibly encouraging those who didn't vote to decide whether they would like a second chance to do so.
That way, the Brexiteers really could claim that this is the will of the people rather than dragging a dead horse over the finishing line
