TWO of Wiltshire’s five MPs say that Boris Johnson is “finished” as Prime Minister after two senior Cabinet Ministers dramatically resigned this evening and a third ministerial resignation is said to be in the offing.

The PM was left teetering on the edge as Chancellor Rishi Sunak and Health Secretary Sajid Javid both quit his Cabinet within minutes of each other.

And South West Wiltshire MP Dr Andrew Murrison said he was aware of a third ministerial resignation that is likely to take place later this evening.

Dr Murrison, who tonight handed in his own resignation to the Prime Minister as Trade Envoy to Morocco, said: “It is collapsing. This is the end. His position now is unrecoverable."

In a letter posted on his Twitter account, Dr Murrison described the letter by Lord McDonald to the Parliamentary Commissioner for Standards released this morning as the 'last straw of the rolling chaos of the last six months'.

"Others must square, as best they can, their continuing enjoyment of your patronage with their personal sense of decency, honour and integrity but I no longer can". 

"Your position has become unrecoverable. I strongly urge you to resign", he said in his letter. 

Dr Murrison added: “After the failure of backbenchers to get rid of Boris Johnson it was made plain to senior Cabinet Ministers that the ball was in their court. Only they could easily do this.

“So this rather pre-empts a change of rules at the 1922 that would enable us to have another ballot fairly soon on Boris Johnson’s leadership.

“The catalyst has been Simon McDonald’s statement this morning. Without going into too many details, I expect a third Ministerial resignation in the near future.

“There is going to be another one and that is probably going to be later today.”

“It is men and women in grey suits. With such high level resignations I don’t think his position is remotely sustainable. He will have to announce that he is stepping down.”

James Gray, the MP for North Wiltshire, said: “It wouldn’t be a surprise if they all went. I think he is finished. What happens next, of course, we’ll have to see.”

The Wiltshire Times has also attempted to contact Chippenham MP Michelle Donelan, the Universities Minister, for a comment. Danny Kruger, the MP for Devizes, declined to comment.

Mr Johnson was hit by the double blow shortly after the Prime Minister issued a grovelling apology over his appointment of shamed MP Chris Pincher.

In his resignation letter, Mr Sunak told the PM that “we cannot continue like this”.

Mr Javid publicly questioned Mr Johnson's integrity, competence and ability to act in the national interest.

He told the PM: “It is with enormous regret that I must tell you that I can no longer, in good conscience, continue serving in this Government.

“I am instinctively a team player but the British people also rightly expect integrity from their Government.'

Mr Javid added: “The tone you set as a leader, and the values you represent, reflect on your colleagues, your party and ultimately the country.

“Conservatives at their best are seen as hard-headed decision-makers, guided by strong values.

“We may not have always been popular, but we have been competent in acting in the national interest.

“Sadly, in the current circumstances, the public are concluding that we are now neither.

“The vote of confidence last month showed that a large number of our colleagues agree. It was a moment for humility, grip and new direction.

“I regret to say, however, that it is clear to me that this situation will not change under your leadership - and you have therefore lost my confidence too.”
