Former Home Secretary Priti Patel is set to fire a warning shot at Liz Truss and Kwasi Kwarteng today as the PM tries to hold her fractured party together.
Ms Patel is expected to tell a conference meeting later that the Tories will "live or die" by its economic credibility - after nearly two weeks of chaos following the mini-budget and a screeching U-turn on tax cuts for the rich.
The ex-Cabinet minister, who quit before her expected sacking last month, will accuse Ms Truss and Ms Kwarteng of "spending today with no thought of tomorrow".
