British PM faces fresh threat of Brexit rebellion

Leading Brexit supporters on Wednesday denied reports they were manoeuvering to remove Prime Minister Theresa May -- while stepping up opposition to her plan to withdraw Britain from the EU.

Up to 50 of May's Conservative MPs held a meeting late Tuesday at which they reportedly openly discussed how to unseat her, amid anger over her proposal to keep close trade ties with the European Union after Brexit.

"There's a great deal of anxiety among colleagues in parliament," former Brexit minister Steve Baker, who chaired the meeting, told AFP.

He said however he personally was no part of any leadership challenge, while another MP who attended said only five or six MPs openly discussed removing May.

The meeting was held by European Research Group (ERG) of MPs, which is outlining alternatives to the prime minister's plan.

ERG leader Jacob Rees-Mogg, who did not attend Tuesday's meeting, told reporters at an event on Wednesday that he wanted May to stay on.

"I have long said, and repeated again and again, that the policy needs to be changed but I am supporting the person," he said.

Former Brexit secretary David Davis, who quit the government over May's plan in July, told the same event: "We have got a very good prime minister and, like Jacob, I disagree with her on one issue -- this issue."
