Personally I'm not sure what the issue is with sacking Kwarteng, blaming him and getting the new Chancellor to make the u-turn. Hasn't Truss been in hiding anyway?
I think the bigger issue is how much advice Truss and Kwarteng ignored to get this through. Including sacking a treasury advisor who objected. i don't think Truss can just pretend that its all Kwarteng's fault.
Are you referring to Sir Tom Scholar? Because he was a bit more than a Treasury adviser, he was the Permanent, i.e. the most senior civil servant in the Treasury.
