A Birmingham MP faces a fight in the House of Commons to keep his job as head of the organisation charged with driving forward renewal in the city.
John Hemming (Lib Dem, Yardley) has come under fire from Labour MPs who want him to quit his role as chairman of the Birmingham Strategic Partnership.
The body is supposed to bring together a wide range of agencies, from the city council to health services, to tackle deprivation and oversee more than £100 million of Neighbourhood Renewal Fund expenditure in Birmingham.
But Labour critics claim the outspoken Liberal Democrat MP is a divisive figure - and the wrong person to lead an organisation designed to bring the city together.
Mr Hemming took on the role in 2004 when he was deputy leader of Birmingham city council.
But now that he is MP for Birmingham Yardley, a seat he won from Labour, his political opponents are demanding he stand down.
In typically robust fashion, Mr Hemming made it clear he had no intention of quitting - and claimed Labour backbenchers were "jealous" of him for heading such an influential body.
In the past, he has faced pressure from the Government to give up his role.
Mr Hemming claimed officials pressured him to resign at "sly meetings in corners" - and threatened to withhold £32 million in regeneration funding earmarked for Birmingham if he failed to comply.
But he saw them off by writing to Cabinet Minister David Miliband threatening to take the Government to court if it tried to unseat him.
Now the conflict is set to erupt in the House of Commons as Mr Hemming leads a debate criticising Government regeneration policy today.
He is claiming that civil servants accountable to Whitehall have interfered in the work of the strategic partnership and causing decisions to be delayed. But Labour MPs intend to use the debate as an opportunity to call on Mr Hemming to stand down.
One said: "The whole point of the strategic partnership is that it brings people together. But as long as John Hemming is in charge it cannot do its job, because people just don't want to work with him."
Another Labour MP, Steve McCabe (Lab, Hall Green) said: "John seems to want to do it all - be an MP , a councillor, unofficial leader of the Lib Dem Group in Birmingham, and this. The question he should be asked is, why doesn't he do the job he was elected to do as an MP?"
Mr Hemming said: "I find these objections strange - maybe they are jealous."
Organisations involved with Birmingham Strategic Partnership include Advantage West Midlands, the regional development agency; Centro, which promotes public transport in the region, and Birmingham Council for Voluntary Services.
