Boris Johnson will chair the first meeting of his new cabinet later – the day after a dramatic change, Sajid Javid shocked Westminster by stepping down as chancellor.
Javid said he was "out of option" but left his post after the prime minister ordered him to fire his closest advisers and replace them with advisers chosen by number 10.
The former chancellor said this is a condition that "any self-respecting minister" would reject, leading him to walk.
Javid: I had no option, but giving up
Rishi Sunak, his former deputy at the Treasury, was named as his replacement.
Javid, who became the chancellor who served the most in 50 years, made several specific references to the line in his letter of resignation to the prime minister.
The former chancellor said that "it is crucial for the government's effectiveness to have people around you who can give you clear and sincere advice."
And he said to Mr. Johnson, "I ask that you ensure that the Treasury as an institution maintains the greatest credibility possible."
Javid's departure – which came after weeks of tensions between him and Prime Minister Dominic Cummings' chief aide – puts the date of the next budget on March 11 in doubt.
& # 39; power grab & # 39; will the PM make a difference in the budget?
Downing Street declined to guarantee that it would go ahead as planned, with a spokesman saying only that "extensive budget preparations have already been made and will continue on pace".
Sunak, whose promotion marks a rapid increase in someone who became a deputy in 2015, said his "predecessor and good friend Saj" did a "fantastic job" as chancellor.
"It was a pleasure to work with him and I hope to be able to develop his excellent work going forward," he added.
In the hours following Javid's resignation, Downing Street confirmed that a new joint team of special advisers was being established at number 10 and number 11 to advise the prime minister and his new chancellor.
Javid was among several victims in Johnson's first major makeover since entering Downing Street in July:
- Julian Smith was fired as Northern Ireland secretary – months after helping deliver a power-sharing deal to the region
- Andrea Leadsom, a former candidate for conservative leadership, was fired as business secretary
- Esther McVey, another conservative crown candidate in last year's contest, lost her job as housing minister
- Geoffrey Cox saw his time as attorney general ended
- Theresa Villiers was fired as secretary of the environment
The prime minister will assemble his new core team on Downing Street this morning, in addition to finishing the remaining nominations for the most junior steps of the ministerial ladder.
Among those who will receive new jobs in the office are Business Secretary Alok Sharma, International Development Secretary Anne-Marie Trevelyan, Culture Secretary Oliver Dowden, Environment Secretary George Eustice and Attorney General Suella Braverman.
Several key players have maintained their positions, including Secretary of Foreign Affairs Dominic Raab, Secretary of Interior Priti Patel, Secretary of Health Matt Hancock and Chancellor of the Duchy of Lancaster Michael Gove.

The number of women who participated in the cabinet fell after the remodeling, from eight to seven.
There are also fewer women in the highest positions.
