Sajid Javid has quit as chancellor after Number 10 ordered him to sack his team of aides.
Boris Johnson had been expected to keep Javid in post, so news of his resignation shocked Westminster, with the chancellor himself due to deliver the post-Brexit budget to oversee financial stability as the UK leaves the European Union.
Allies of the former chancellor said Johnson had ordered him to fire all of his senior aides if he wanted to remain at the Treasury – something Mr Javid refused to do.
The bombshell came after long-standing rumours of tensions between the ex-chancellor and Johnson’s closest aide Dominic Cummings.
In August he had fired Javid’s aide Sonia Khan and it appears Number 10 wanted to go further in keeping a closer eye on the chancellor.
Javid said that “no self-respecting minister” could accept the condition being imposed.
“He has turned down the job of chancellor of the exchequer,” a source close to Javid said.
“The prime minister said he had to fire all his special advisers and replace them with Number 10 special advisers to make it one team.
“The chancellor said no self-respecting minister would accept those terms.”
