The leftards response to Dominic Grieve being held to account by his constituency party as exemplified by Phil Wilson who said the vote was "ridiculous", adding: "I'm not of the same politics as Grieve but to deselect him as a Conservative candidate is to diminish politics, see an end to political integrity and deprive politics of a sincere and thoughtful practitioner."

Grieve’s arrogance was that he thought he could shift from promising his members – in writing – that he would respect the outcome of the referendum, to leading the efforts to thwart Brexit, without cost. Breaking your word to voters, particularly the ones who get out the vote for you, is risky.

or as another wit says:Dominic Grieve said in the Commons a few days ago he had never been so ashamed to be a Tory.

Last night, his local Conservative party voted that they were ashamed to have Dominic Grieve as their MP.

Should be the quickest case ever through the divorce courts if both sides are that fed up with one another !!

Douglas Carswell states it very well:

“If Dom Grieve is a brilliant MP like other MPs are claiming, he’d have no qualms about calling a snap by election and getting a mandate directly from his electorate. You’ve only got to put it like that to realise that he’s just another safe seat MP with tenure."

It begins to look as though we have an entire party(/parliament) that believes it can sit in "tenure".
If nothing else, the Brexit vote has exposed this perilous state, and it can’t be sustained.
