According to the Telegraph, roughly a third of Tory MPs will not support their PM. Another third are employed by the government in way or another, so there is no way of telling what degree of support she has from them unless they resign. So there are only a third of her MPs who are certainly supporting her. Seeing as she is so unpopular, why did the ERG have to make themselves look so foolish calling for just 48 letters to have her removed, and failing to get them sent?
What current polls are showing are that the population would rather stay in the EU in preference to accepting the May proposal or the No Deal departure. Clearly as the people realise that they were sold something that could never happen, they are facing up to making hard decisions. After two years of any government it is normal for people to change their minds, and this has happened. To say that they cannot is not democracy.
