I'm sick of hearing that lie. It is based on the total number of votes for the two biggest parties but I'm pretty sure many, if not most Labour voters, and many Tory voters cast their votes for other reasons.
Mind you, it would have been better if Labour had not caved in as much as they did on Article 50 and had less of the brexit nonsense in their manifesto. Brexit may be likely to happen, but it is not inevitable and the "brexit at any price" policy of May is suicidal.
I've noticed that the most outspoken brexiters always seem to be angry, issuing threats about what will happen if "brexit is thwarted" and carping on about the "will of the people".
The more people understand about the likely consequences, the fewer people want to jump of that cliff. How bad would things have to be before these folk see sense?
