The Labour MP Chris Leslie has lost a vote of confidence from his Nottingham East constituency party.

Activists voted to pass the no-confidence motion on Friday night, citing his involvement in a plot to oust Jeremy Corbyn as leader and criticising what they said were his “repeated attempts … to undermine the leadership”.

It comes after Corbyn called for a much greater culture of tolerance and “the freedom to disagree and debate” at the Labour conference.

The motion, brought by members of the Mapperley branch of Nottingham East, attacked the former shadow chancellor for his “disloyalty and deceit”.

They said this was “a severe impediment to Labour party electability” that was “incompatible” with him continuing as the Labour candidate for the constituency.

Louise Regan, the chairwoman of the Nottingham East Labour party, said: “We overwhelmingly passed a motion of no confidence in our MP Chris Leslie.

“It was agreed that this information would be shared with the press, but that we would also make clear that members of the CLP [constituency Labour party] would be out campaigning on the national day of action, building support for Labour policies and a Labour government.”

Leslie has previously said the “starry-eyed, hard-left” economic strategy embraced by the Labour leadership would hand the Conservatives at least another decade in power and end up hurting poorer people, as interest rates and inflation rose.

Such votes carry no official authority, but activists can hold a “trigger ballot” that would force the sitting Labour MP to compete for selection as a general election candidate.

Leslie and his supporters boycotted the meeting and said he had been unfairly targeted. The former frontbencher criticised what he called the intolerance of differing opinions within sections of the party.

“Sadly, differing opinions are no longer tolerated in some parts of the Labour party,” he told the BBC. “But I have to weigh the views of a few dozen people at this meeting with the thousands who voted for me at the last election.”

Chuka Umunna, who has previously urged Corbyn to “call off the dogs” targeting Labour MPs, quoted the party leader’s words in his speech to the conference on Wednesday.

Jeremy Corbyn, 26.09.18:

“Real unity is based on the freedom to disagree and debate...

“So we need to foster a much greater culture of tolerance...

“We must learn to listen a bit more, and shout a lot less. To focus on what unites us.”

The Luton South MP, Gavin Shuker, Joan Ryan, the MP for Enfield North, and Frank Field, who quit the parliamentary party earlier this month, have also faced no-confidence votes from their local parties.

A compromise deal making it easier for CLPs to remove MPs was passed by the conference in Liverpool, reducing the threshold for triggering an open selection contest from 50% to 33% of local party branches or affiliated unions.
