Liz Truss and Kwasi Kwarteng are under pressure to U-turn over key parts of the mini-budget to help restore confidence in the Government's economic plans. With Ms Truss' leadership already being questioned after little more than a month in the job, Foreign Secretary James Cleverly said a change at the top of the party would be a "disastrously bad idea".
Downing Street insisted there were no plans for further changes to the mini-budget package. However the financial markets appear to be expecting further moves to ditch elements of the Chancellor's tax-cutting plans in order to demonstrate a commitment to balancing the books.
The mini-budget's plan to increase borrowing to fund tax cuts caused turmoil on the financial markets, which sent Tory poll ratings plummeting. It eventually led to Mr Kwarteng abandoning plans to scrap the 45p rate of income tax for top earners.
