Conservative MP Nigel Evans has said that he wants to see Theresa May step down as prime minister and a new leadership contest to take place “as soon as possible”.
On Monday, it emerged the prime minister could face an unprecedented vote of confidence in her leadership after 70 local Conservative association chairs signed a petition in support of a poll.
They called for an extraordinary general meeting of the National Conservative Convention to discuss the Prime Minister's leadership of the party, The Telegraph reported.
A non-binding vote is expected to be held at the meeting, which would - if it showed a lack of confidence - put pressure on the 1922 Committee of Tory MPs to find a way of forcibly removing the PM from office.
Mr Evans, a member of the 1922 Committee told talkRADIO’s Julia Hartley-Brewer: “We were told to reflect over the options over the Easter break and I have thought long and hard about this.
“I have been fiercely loyal towards Theresa May when she had that awful general election and dreadful manifesto.
“I supported her then and said that she should continue. I supported her when there were calls for her to go after the party conference.
“But I have reflected long and hard over - what I would say has been - catastrophic handling of the Brexit negotiations.”
The MP for Ribble Valley added that Mrs May should go “as quickly as possible”.
“My recommendation will be that we should say to the prime minister that she could now go as quickly as possible,” he said.
“If she should refuse to do so – I am talking about a matter of days – we need a new leadership contest to begin as quickly as possible.
“We should look to change the rules or have indicative votes where we do not need to change the rules but at least then we can test the opinion of Conservative MPs.”
