Really? People rejected one party that promised Brexit, and voted in another party that promised Brexit. This election wasn't about Brexit, it was about sticking with the Tories instead of risking it all on Labour.
Meanwhile, support for Remain is over 52% and has been for at least 18 months.
This vote is a clear mandate for Brexit, and there was no secret made of it. It was really, really clear what a vote for the Conservatives would entail. Look at the map in the OP, the English electorate own this result. If anyone continues to claim that the English want to remain in the EU then I'm really not sure how that can be backed up.
OK... but what do the other three countries of the UK want, then?
The Scottish position has only strengthened for remain. Wales & NI I'm not so sure, but Wales have rejected the Tory version of Brexit and it's interesting that the a Westminster DUP leader lost his seat to Sinn Fein.
