Jason Stein, a special adviser to Liz Truss, is to face a formal probe by the Cabinet Office propriety and ethics unit.

Sky News’s political editor Beth Rigby said it was “another crisis emerging for Liz Truss within her own team”.
The suspension was confirmed just before Ms Truss began her third session of Prime Minister’s Questions in the Commons as she battles to hold onto her premiership following Mr Kwarteng’s removal and reversal of most of her government’s mini-budget.
The PM made a public apology in the Commons as she faced questions from Labour leader Sir Keir Starmer for the first time since her economic plan was ditched by new Chancellor Jeremy Hunt.

Discussing the swathe of economic policy U-turns carried out by Mr Hunt on Monday, Ms Truss continued: “The right thing to do in those circumstances is to make changes, which I have made, and to get on with the job and deliver for the British people.”

The PM has risked a fresh fight with Tory MPs by making a vote on a Labour motion on fracking a test of confidence in her administration later today.
But amid growing calls for her to resign, Ms Truss insisted she is “a fighter not a quitter” after Sir Keir said the Conservatives’ economic credibility is “gone” and asked the PM: “Why is she still here?”
