Rishi Sunak is rumoured to be planning a cabinet overhaul, which could see Suella Braverman removed as home secretary.
The idea of a rearrangement has already been explored, according to insiders.
“Until the formal confirmation of a reshuffle, we won’t know for sure whether Rishi Sunak intends to oust his home secretary on a charge, effectively, of disobedience,” he said.
“We do know, however, it has been discussed, and while we don’t know the resolution yet, one Whitehall source put the odds as high as 90% on Sunday afternoon that it would be a Monday.”
Ms Braverman has been accused of inflaming tensions by writing an article in The Times last week accusing the Metropolitan Police of having double standards in how it polices different protests based on political affiliation.
Following the publication of the piece, Mr Sunak has received calls from Labour to resign as home secretary, and Downing Street is presently examining how it was released without the revisions they desired.
On Friday, the prime minister appeared to downplay any potential schism between him and Ms Braverman, saying he had “full confidence” in his home secretary.
However, Defence Secretary Grant Shapps refused to say, when asked, whether Ms Braverman would remain in post in a week’s time.
Instead, he told Sunday Morning with Trevor Phillips that a “week is a long time in politics” and that he would not be making any predictions.
On Sunday night, Ms Braverman doubled down on calls for more action to be taken against pro-Palestine protesters.
In a series of posts on X (Twitter), Ms Braverman said “further action is necessary” against the protests, which were resulting in “the streets of London… being polluted by hate, violence, and antisemitism”.
The home secretary paid tribute to officers, saying “our brave police officers deserve the thanks of every decent citizen for their professionalism in the face of violence and aggression from protesters and counter-protesters in London yesterday”.
