/'The game is up': First Tory publicly says PM should go
Crispin Blunt, the Conservative MP for Reigate, has become the first to publicly state Prime Minister Liz Truss should step aside, saying: "The game is up".
He told Channel 4's Andrew Neil Show that he does not think Ms Truss, who has been in Number 10 for little over a month, can survive the current crisis.
"I think the game is up and it's now a question as to how the succession is managed," he said.
Asked how the party will get rid of her, he said: "If there is such a weight of opinion in the parliamentary party that we have to have a change, then it will be effected.
"Exactly how it is done and exactly under what mechanism... but it will happen."/
Oh dear. How sad. Never mind.
