Jon Cruddas had been tipped to get a ministerial job
Gordon Brown has completed his ministerial reshuffle and, despite speculation he may join the government, there is no job for Jon Cruddas.
It had been reported that the MP, who came third in Labour's deputy leadership contest last year, turned down a position as housing minister.
Margaret Beckett, the former foreign secretary, was appointed to that role.
There is promotion for Phil Woolas, a move for Lord Adonis, while there is a job for former Tory MP Quentin Davies.
Four of the MPs who signed the backbenchers' letter which prompted Mr Brown's predecessor Tony Blair to announce a timetable for his resignation in 2006 each gained ministerial office.
Tom Watson becomes parliamentary secretary to the Cabinet Office, Chris Bryant officer of the leader of the Commons, Kevan Jones parliamentary under-secretary in the Ministry of Defence and Sion Simon gets a junior post in the Universities Department.
Those ministers leaving the government include Kim Howells, Malcolm Wicks and Margaret Hodge.
However, Mr Wicks has been named a special representative to the PM on energy issues while Mrs Hodge has stepped down for personal reasons and will return to the government next year.
The reshuffle was dominated by Peter Mandelson's surprise return to government as secretary of state for business.
Pat McFadden MP, a former policy advisor to Tony Blair, will act as Mr Mandelson's deputy, and with Mr Mandelson set to take a seat in the Lords, will represent the department in the Commons.
Other key middle-ranking appointments made over the weekend saw Phil Woolas become the new immigration minister and Vernon Coaker named as policing minister.
Mr Woolas moves from the environment department where he was responsible for climate change and energy policies while Mr Coaker is promoted from a more junior role in the Home Office.
Other promotions see Ian Pearson become economic secretary to the Treasury while Steven Timms replaces Jane Kennedy as financial secretary, Ms Kennedy moving to number two at environment.
Lord Adonis, who championed city academies and widely seen as an education specialist, moves from the schools department to become minister of state at transport.
Mike O'Brien and Lord Hunt of Kings Heath have been given ministerial posts in the new energy and climate change department.
In other moves, Sadiq Khan MP has a new job in the communities and local government department while Jon Trickett becomes parliamentary private secretary to the PM.
This move was beingseen as going some way to placate those on the left of the party after Peter Mandelson's appointment.
Meanwhile, Quentin Davies, who defected to Labour last year, gets a job in the Ministry of Defence.
Mr Woolas told the Sunday Times he felt immigration was the second biggest problem facing the population and he would "toughen" up current legislation on the issue.
The MP for Oldham East and Saddleworth was at the centre of controversy earlier this year when he raised concerns that the practice of first-cousin marriage in Britain's Pakistani community was leading to high levels of birth defects.
Mr Khan told BBC News Mr Brown rang him to break the news.
He said: "I'm very pleased. It is a pleasure for me to join the communities and local government team."
In another change, Shahid Malik has become justice minister.
The Dewsbury MP said he hoped to make Britain "a more just society" in his new role as a minister in the Department for Justice.
Transport Minister Tom Harris was one of a handful of ministers to lose their jobs in the reshuffle.
A message published on Mr Harris's website said he was told the news by the prime minister in a phone call to his Glasgow home on Friday evening.
"Obviously I'm disappointed; I really enjoyed being a minister, particularly in the Department for Transport," Mr Harris said on his website.
"But I was always realistic - ministerial jobs come and go, but the role of an MP is more important than any other. And of course I will continue to support the government from the backbenches."
The reshuffle could force Conservative leader David Cameron to follow suit with his shadow cabinet.
The changes would have to take account of the structural changes made to the government, including the creation of a new Department for Energy and Climate Change, led by Ed Miliband.
