Labour MP Kate Hoey has accused Theresa May of running a “mini-dictatorship” and called for her to resign.
Speaking to talkRADIO's Mike Graham the MP for Vauxhall said: “The prime minister should resign. She has lost the confidence – not just of the Leave MPs – but also of her own party.
“She is determined to stay there. There is an irony in our great democracy that we have got a prime minister that very few people want to keep in post on all sides and yet she can stay there.
“It is a mini-dictatorship in a way until they can come back in December and try to oust her.”
Mrs May won a confidence vote in December which means MPs cannot table a similar vote for 12 months.
Ms Hoey said that if Brexit had been handled differently the UK could have left the EU by now.
“The only way the EU seems to change anything is if they really think that we are serious," she said.
“The problem is that from day one the prime minister has shown that she is not really serious.
"I'm exasperated and angry and, if I am feeling like that then I know millions of people around the country are feeling completely let down.”
