Anyway, didn't Ireland have a second stage of voting? it's not unheard of. It would be sensible for May to check that most people are with her as she jumps over the cliff.
It might be sensible in a national sense, but for May, Brexit has removed from the Tories John Major's 'bastards' and the primary cause of strife within that party for the last 30 years. She'll not jeopardise that for any money!
