How on earth do you come to a conclusion that the Tory related vote was a Leave vote?. My interpretation , at least as valid, is that it was a Remain vote. Any Tory voter who was pro hard Brexit would have voted for the ..err Brexit Party (Recall that before the election that was the presumption.). I would not make the same conclusion for the Labour related vote,which was and is ambiguous. The best ..from your viewpoint which could be attributed to the Tory and Labour vote,was that tgey prefer a Soft Brexit..or a Brexit with a Deal.
Having said that,a 32% national vote for an organisation (Brexit Party) which did not exist a month ago is an incredible result.
