The former Chancellor resigned on Thursday after he was asked to fire his entire team of advisers in exchange for keeping his position. But speaking on Newscast, BBC News political editor Laura Kuenssberg revealed she was warned of the sudden move two days before it unravelled. She said: “Somebody who knows Sajid Javid very well was saying to me a couple of days ago, he was saying ‘I think they might try and do this, and if they do this what should I do?’ And, of course, there’s previous here because another former adviser of his, Sonia Khan, was fired pretty unceremoniously at the very start of Johnson’s Government.”
Echoing Ms Kuennsberg’s revelation, former adviser to Sajid Javid, Salma Shah, added: “There was a piece on Conservative Home by Paul Goodman that actually categorically stated that two of the Chancellor’s advisers would be fired in exchange for his job.
“And the fact that it was such a good news source, I think prompted a lot of questions just in the Westminster village generally.
“And it was so categorical, that it obviously prompted questions about why had this been stated.
“Because I don’t imagine Conservative Home would have published that unless they had some very good sources.”
BBC News: Laura Kuenssberg reveals she was warned about Sajid Javid's resignation
Mr Javid accused the Prime Minister of setting conditions "any self-respecting minister" would reject - seen as a thinly veiled swipe at his successor.
And he told Mr Johnson in his resignation letter that he believed it was "important as leaders to have trusted teams that reflect the character and integrity that you would wish to be associated with".
The bombshell - less than a month before the Budget - follows tensions between the ex-chancellor and the PM's chief adviser Dominic Cummings.
In August, Mr Cummings fired Mr Javid's aide Sonia Khan and it appears Number 10 wanted to go further in keeping a closer eye on him.
The move - viewed by critics as a power grab by Mr Cummings - means Britain is on to its third chancellor in a year.
Downing Street refused to guarantee that next month's Budget would go ahead as scheduled, with a spokesman saying only that "extensive preparations have already been carried out for the Budget and they will continue at pace".
The Prime Minister's decision to give Number 10 more oversight over the Treasury has been defended by Communities Secretary Robert Jenrick.
Mr Jenrick, a former Treasury minister, told BBC Breakfast: "What was proposed and is now going to happen is that we bring together the back office teams that advise the Prime Minister at Number 10 and those that advise the Chancellor.

"I think that is sensible because we have a lot to do.
"We need to have a strong team that is working as one and that is exactly what we are going to do."
Sajid Javid was replaced by Rishi Sunak, former Treasury Chief Secretary.
Mr Javid's departure came after Julian Smith was unceremoniously dumped as Northern Ireland secretary just weeks after brokering the deal that restored the power-sharing administration at Stormont.
