Almost as soon as David Blunkett resigned as home secretary last December, speculation began that he was poised to return to the front bench after the general election.
Mr Blunkett is a Labour loyalist from a working class family
Before quitting over claims his office had fast-tracked a visa application for his lover's former nanny, his responsibilities included race, policing, immigration, security and terrorism.
He was named home secretary after the 2001 general election, after which the focus on his office intensified.
The attacks on the World Trade Center on 11 September 2001 heightened concern for security and immigration in particular.
A Labour loyalist from a working class background Mr Blunkett, 57, had been unafraid of pushing for tough changes to Labour policy.
'Airy fairy libertarians'
Identity cards had provoked controversy with critics questioning their cost and infringement of civil liberties.
Mr Blunkett was also at the centre of a scandal involving the former immigration minister Beverly Hughes.
Having received his full backing, Ms Hughes was forced to resign in April over abuses in the visa processing system, of which she said she was unaware.
Mr Blunkett's own comments on immigration had prompted censure - he told refugees from Afghanistan and Kosovo to "get back home" to start rebuilding their countries.
And he also urged people from ethnic minorities to develop a "sense of belonging" in Britain, telling them to speak English at home.
Avoiding political correctness is second nature to the former home secretary, who spurns a metropolitan elite and "airy fairy libertarians". He coined the phrase "liberati", as an amalgam of "glitterati" and "liberal".
Yet in January 2004 he courted further controversy over his seemingly liberal reclassification of cannabis, from a Grade B to Grade C status drug .
Before the furore over his affair with a married woman and claims he helped her former nanny get a visa, Mr Blunkett had always appeared more interested in politics than his personal life.
He told the Daily Telegraph in 2001 that he continued to wear his wedding ring, in spite of being a divorcee, as "a useful way of ensuring that people don't casually think I am available".
He added: "I am not available because I am just getting on with the job."
Mr Blunkett entered Parliament for Sheffield Brightside in 1987, after first contesting the Sheffield Hallam seat in 1974.
He is one of very few blind MPs, and was the first to reach the front bench and the Cabinet.
His relaxed performances - with his guide dog by his side - at the despatch box, in the Labour Party's National Executive, and on the conference platform made it easy to forget his disability.

Mr Blunkett himself described not being able to see as simply "an inconvenience".
Using Braille for speeches, and briefed by his officials on tape, he also has a sharp tongue at times, and a pragmatic approach to politics.
Mr Blunkett was schooled in Sheffield where he led the city council for seven years before entering the Commons.
He chaired the Labour Party nationally, and was a unifying force in the 80s and 90s, shadowing health and education.
In Tony Blair's first government Mr Blunkett was put in charge of education and employment, where he won big increases in funds for schools, while insisting on improved standards of literacy and numeracy.
He was prepared to stand up to the teaching unions - which sometimes heckled his speeches - and his policy of charging university students for tuition fees was not popular.
In the Labour Party he has been regarded as a loyal colleague, a conciliator who avoids factions, and a man whose humour and determination make him widely popular.
There have been wry smiles as well. In 1999, his then guide dog Lucy threw up in the Chamber during the speech of his Tory opponent.
Lucy was replaced by her half-sister, Sadie, a black Labrador-curly-coated retriever cross, in 2003 after nearly a decade by Mr Blunkett's side.
