Conservative MP Sir Charles Walker has been talking to our political editor Beth Rigby and has not held back on his feelings towards the prime minister.
“I think her position is untenable,” he said.
“She has put colleagues, the country, through a huge amount of unnecessary pain and upset and worry.
“We don’t need a disruptor in No 10. We need an uniter.
“I just think… it is just a situation that is… it can only be remedied I think, with a new prime minister.”
Asked about Ms Truss staying in her position, Mr Walker says: “Look the prime minister has had a very torrid six weeks.
“Personally, I don’t think her position is recoverable. She would obviously take a different view.
“But if you read the mood of the parliamentary party, she has lost authority and you can’t lead a party if you don’t have some authority. She doesn’t have much of that.”
Pressed on whether he is calling for Ms Truss to go, Mr Walker replied: “I think it’s her decision right now. I think if she doesn’t go right now, it will not be her decision. That agency will be taken away from her.”
Asked how long he thinks it will be before that decision gets taken one way or the other, Mr Walker says: “A week or two.”
The MP for Broxbourne, who is standing down at the next election, continued: “I’m just so cross. I’ve just had enough. And I think quite a few of my colleagues have had enough and I’ll be dismissed as being tired and emotional.
“And yes, I am tired, and I am emotional, and I am angry. And I’m in the same place as many of my friends, many of my family, and many of my constituents.”
