A fourth Conservative MP has called on the Prime Minister Liz Truss to resign as her position is not “tenable any longer.”

The Prime Minister is facing a Tory rebellion and it has been reported that more than 100 MPs could be set to send letters of no confidence to the 1922 Committee.

On Monday Angela Richardson, MP for Guildford, told Times Radio, “I just don’t think that it’s tenable that she can stay in her position any longer. And I’m very sad to have to say that.”

Truss is under pressure and she is on the ropes as she has been accused of being “in office but not in power” and three other Tory MPs have also publicly called on her to quit after just six weeks being in the job.

Following the economic turmoil of recent weeks Tory MPs Crispin Blunt, Andrew Bridgen and Jamie Wallis have all told her to quit and the Labour leader has accused Truss of of being “in office but not in power.”

Blunt told Sky News that the “game is up,” adding, “The principal emotions of people watching her, doing her best to present, is some combination of pity, contempt or anger.

“I’m afraid it just won’t wash and we need to make a change.”

Wallis tweeted, “In recent weeks, I have watched as the government has undermined Britain’s economic credibility and fractured our party irreparably. Enough is enough.

“I have written to the prime minister to ask her to stand down as she no longer holds the confidence of this country.”

Bridgen said, “our country, its people and our party deserve better.”
