AN MP resigned from a Commons equality committee last night after it emerged he had mocked gay people and ‘fatties’, and joked about beating up women.

Labour’s Jared O’Mara also wrote online several years ago that Girls Aloud should sack Sarah Harding and the other four members could ‘come and have an orgy with me’. He claimed singer Michelle McManus only won TV’s Pop Idol ‘because she was fat’.

The 36-year-old, who ousted former Lib Dem leader Nick Clegg to become Sheffield Hallam MP in June, bowed to calls for him to resign from his role on the women and equalities select committee.

He said: ‘I understand why the comments are offensive and sincerely apologise for my use of such unacceptable language. I made the comments as a young man, at a particularly difficult time in my life but that is no excuse.’

Mr O’Mara made the remark about Girls Aloud in 2004 on a web forum hosted by the Drowned In Sound music website.

The university graduate also said it would be no great loss to the music world if jazz star Jamie Cullum was ‘sodomised with his own piano’ and ‘died of a sore arse’.

According to the Guido Fawkes blog, he once performed a song with lyrics that went: ‘I wish I were a misogynist, I’d put her in her place, I wish I were a misogynist, I’d smash her in her face.’

The former bar boss, who was born with cerebral palsy, is also believed to be behind posts on a fan site for singer Morrissey that referred to gay men as ‘poofters’ and ‘fudge-packers’.

One post from ‘gingerjared’ said: ‘I find it funny how some homosexuals think they have the monopoly on being subject to abuse, they should try being Ginger AND Disabled!’

In his comments about McManus, he added it was wrong to ‘deify fatties’, adding: ‘There is nothing noble or admirable about glutting on loads of fatty foods.’

Mr O’Mara, who revealed he was single and ‘open to offers’ earlier this year, said he had changed since he made the comments from 2002 to 2004.

He resigned at the weekly meeting of the parliamentary Labour party and confessed to having previously held homophobic and sexist views.

His ‘honesty and openness’ were well received by his colleagues, a party source told Metro.
