Labour has suspended former shadow Northern Ireland Secretary Ivan Lewis following a complaint about his conduct.
The Bury South MP is under investigation by party officials.
A spokeswoman said: "The Labour Party takes all allegations of sexual harassment extremely seriously. Ivan Lewis is currently suspended from the Labour Party pending an investigation."
Earlier this month it was reported that a woman alleged Mr Lewis had touched her leg and invited her to his house in 2010.
Mr Lewis said he had "never made non-consensual sexual comments or sexual advances to women".
