Chris Williamson has been allowed back into the Labour Party four months after he was suspended in an anti-Semitism row.
The MP and Jeremy Corbyn ally will once again sit with the party after he was issued with a “formal warning” by a disciplinary panel.
The Derby North MP and former shadow minister caused outrage in February by suggesting Labour had been “too apologetic” over anti-Semitism.
In a video clip of a Momentum meeting, leaked to the Yorkshire Post, Mr Williamson said: “We have backed off far too much, we have given too much ground, we have been too apologetic.”
Labour sources confirmed Mr Williamson is no longer suspended after his case was considered by an anti-Semitism panel of Labour’s ruling National Executive Committee.
His case was not considered by Labour’s highest discipline body, the National Constitutional Committee.
Party sources said the panel was advised by independent barristers and Mr Williamson is likely to face more severe sanctions, including an NCC hearing, if he repeats such conduct in future.
