Sajid Javid has shocked Westminster by quitting as chancellor of the exchequer in the middle of Boris Johnson's cabinet reshuffle. He rejected the prime minister's order to fire his entire team of aides, saying no self-respecting minister could accept such a condition. He has been replaced as chancellor by chief secretary to the treasury Rishi Sunak - who just seven months ago was a junior housing minister. Mr Javid’s resignation follows rumours of tensions between him and the prime minister's senior adviser Dominic Cummings. He said his advisers had worked ‘incredibly hard’, and he could not agree to them being replaced. ‘I felt I was left with no option but to resign’, he said, adding that Mr Sunak and the rest of the government retained his ‘full support’. Downing Street said there would now be a joint team of economic advisers for both the chancellor and prime minister. For full details of Mr Johnson’s cabinet reshuffle, see
