Theresa May once called sacked defence secretary Gavin Williamson “her b***h”, it has been claimed.

The Sun reported that the prime minister referred to Mr Williamson as “my b***h now” when talking to aides.

It followed reports from her staff to her in 2016 that Mr Williamson had called her a “charisma free b***h”, a remark he has denied making.

The prime minister sacked Mr Williamson two weeks ago, accusing him of leaking the decision from a National Security Council meeting to allow Chinese firm Huawei to build some of Britain’s 5G mobile network.

Mr Williamson has denied being the source of the leak.

On Sunday, Mr Williamson described Mrs May's Brexit talks with Labour as a "grave mistake".

The former defence secretary said pressing ahead with the talks will have "fatal" consequences.

Writing in the Mail on Sunday, he labelled Mrs May as "politically naive" for going into fruitless negotiations which he claimed were bound to fail.

The former Cabinet minister had estimated there were "up to 80" Labour rebels who want another referendum and predicted a "number of defeats".

Urging Mrs May to ditch talks, he said: "The Prime Minister needs to recognise that futile efforts to pull off this Labour deal are damaging us all.

"It is a grave mistake for any Prime Minister to fail to recognise when a plan will not work and it is fatal to press on regardless.

"We need to accept that these talks with Labour are fruitless and that not only will they not deliver the Brexit that people voted for, they are a betrayal of the direct instructions the people gave us in 2016 and 2017."
