Labour Party chiefs were today investigating allegations that a Bradford MP made lewd remarks to a female colleague while drunk.

Marsha Singh said he was unable to comment about claims made in a national newspaper until the probe was completed, probably in a matter of weeks.

Mr Singh, Labour MP for Bradford West, is also awaiting legal advice over accusations that he made an indecent proposal to Labour Reading East MP Jane Griffiths in the early hours of Friday.

Yesterday he told the T&A that there had been "a minor altercation" but insisted "the major allegations I reject totally."

The incident is alleged to have happened in the House of Commons smoking room during a break in the 30-hour debate on the anti-terrorist laws.

The report claimed he also raised his fist, needed rest-raining and was later locked in another room.

It reported that Mr Singh brandished £20 notes and threatened to fight a Labour Whip who was called to calm the situation.

The report also alleges that at one point he offered to pay for sex.

The incident is said to have happened at about 5am when Mrs Griffiths and Helen Clark, Labour MP for Peterborough, arrived in the room.

They were trying to calm the situation when the alleged remarks were made.

Earlier this year Mrs Griff-iths was deselected by Reading East Labour Party over her support for top-up fees and the Iraq war.

Constituency members believed another candidate could unite the local party.

Last June she caused a spat in the Commons after accusing Labour Reading West MP Martin Salter of distributing an "offensive" and "racially inflammatory" letter to constituents during the local election campaign.

She also claimed Mr Salter had bullied her.

Mr Salter claimed the bullying claims were "despicable lies and gutter politics" and said any suggestions the letter was racially inflammatory was "nonsense."

Meanwhile, Mrs Clark was the only other female Labour MP threatened with deselection by her local party - but she survived narrowly by just 11 votes.

The controversial MP sparked a police probe after claiming she was assaulted by her Conservative rival Stewart Jackson while campaigning in her constituency.

But the case was dropped by the Crown Prosecution Service in January because of a lack of evidence.

Mr Jackson has instructed his solicitors to take legal action against Mrs Clark.
