I agree that both Boris and Truss did, and are doing exactly what they said they would. The problem is that the Tory MPs now look at their voters back in their constituencies and think - shit, they don't like what the government are doing, I'm not going to be re-elected. At least Boris had a mandate - Truss doesn't, and she absolutely deserves to go down in flames if she so significantly changes the party policies on which her party was last elected.
I've written to my (Tory) MP on this myself to express my fury so maybe he's one of those sharpening the knives.
It's really a general election that's needed though before anyone can claim a mandate.
(Also please can we avoid gendered insults about Truss - she's doing things you may disagree with but that's not because she's female so calling her a bitch is not on.)
