The catalyst for this virtue signalling came a couple of weeks back. Johnson when from 5th to 1st as Tory Leader and immediately went ten points ahead. Why ? Because many feel Mays chequers plan is a sell out and will keep in tied to the EU. Not my opinion but certaintly theirs. Johnson is very popular among grass roots Tory members these are the ones who vote in the leader. Cue remain Tory attacks and an invented outrage which it seems is blowing up in their face.
So the civil war within the Tory party goes on.
By the end of Brexit there could be splits in both the Tory and labour parties.
Best thing that could happen to Britain.
