Labour MP John Woodcock has been suspended pending an investigation into sexual harassment.
Accusations against Mr Woodcock, a fierce critic of Jeremy Corbyn , emerged over the weekend.
He will be the subject of a hearing before the party’s National Constitutional Committee later this year.
It is alleged the MP sent inappropriate texts and emails to a former staffer during the two years she worked for the party.
And it is said the woman felt uncomfortable and left her job. She claims that Mr Woodcock continued to contact her even after she had quit, sending regular messages and emails.
Last November Labour’s National Executive Committee agreed the woman’s complaint met the necessary threshold to refer the case to the constitutional committee.
In a statement on Monday, Mr Woodcock said: “In the light of newspaper stories today, I want to make the following clear to my constituents.
“I was made aware in December last year that a complaint made against me was being referred to Labour’s national constitutional committee as a potential breach of the party’s policy on sexual harassment.
“I do not accept the charge but know the complaint must be thoroughly and fairly investigated.
“I have not yet been notified of any date for a hearing and was following the party’s guidance that the process should remain confidential to reassure potential victims that they could make complaints without being exposed to unwelcome publicity.
“Therefore I do not intend to discuss details of the issue ahead of any hearing.”
A Labour Party spokesperson said: “John Woodcock has been suspended from the Labour party pending due process.
It would not be appropriate to comment further on an ongoing case.”
