Labour is investigating one of its MPs after it was claimed he had made unwanted sexual advances towards women.
The party said it had received a complaint about Bury South MP Ivan Lewis’s conduct.
It refused to discuss details of the allegation, but said it took all complaints of sexual harassment “extremely seriously”.
Mr Lewis previously denied making any “non-consensual sexual comments or sexual advances towards women”.
In a statement, he said he was sorry if his behaviour towards women he worked with had made anyone feel “awkward”.
He made the comments to Buzzfeed News after it reported a woman alleged he had touched her leg and invited her to his house at a Labour Party event in 2010.
It is understood Mr Lewis has not been suspended by the party and continues to take the Labour whip.
But he has stepped down from his role working with Greater Manchester Mayor Andy Burnham to tackle rough sleeping and homelessness.
“In view of recent press stories I feel it is right that for the time being I step down” from the role, Mr Lewis said in a statement.
He said he hopes to “be able to resume my duties” in the future.
