The first to say he wanted the job as Mayor of London. Lord Archer is a former GLC councillor and in fact was its youngest member when elected at the age of 26 in 1966. He is better known though for his millionaire novelist status. He has already pledged to give his salary to charity if elected and has been running a high profile campaign backing his candidacy.
So far Lord Archer's campaign has included a visit to New York, where he met Mayor Rudi Giuliani, the launch of a web site, and a questionnaire posted to thousands of Londoners. He was Deputy Chairman of the Conservative Party from 1985-6, and made a life peer in the Queen's Birthday Honours List of 1992.
Twelve years ago Tony Banks was the last chairman of the Greater London Council, having worked alongside its leader Ken Livingstone in the campaign to keep it alive.
An MP since 1983, after the demise of the GLC he focussed more on his parliamentary career, and of course his other great love, Chelsea Football Club. Banks is famous for his lively character and a mouth that can sometimes get him into trouble ( as it did when he labelled Tory leader William Hague a foetus).
He was made Sports minister under the new Labour administration, and has the task now of trying to get the 2006 World Cup to England. Has openly said though that he wants to be a candidate for mayor if Londoners decide they want one.
Having set up his own student magazine and Student Advisory centre in his teens, Richard Branson founded Virgin as a mail order record retailer in 1970.
Shortly after this he opened a record shop in Oxford Street and in 1972 built a recording studio which produced the very successful Mike Oldfield album, Tubular Bells.
The equity of Virgin Music was sold to Thorn EMI in 1992 in a 1 billion US dollar deal. Virgin Atlantic Airways, former by Branson in 1984, continued the success of the name and is now the second largest British long haul international airline. He has since added other divisions to his business empire including financial services and Virgin trains.
Personal ambitions have led him to become involved in record breaking attempts including the Challenger crossing and balloon expeditions to cross the Atlantic and circumnavigate the globe.

Long parliamentary career, appointed Health Secretary in May 1997. Experienced and popular cabinet figure who is currently favourite to get Blair's nod as the Stop Ken candidate. But he's unlikely to quit the cabinet when he's doing better than expected. Lives in a council flat in his Holborn and St Pancras constituency where he's been a MP since 1979. He was also leader of Camden council in the 1970s.

Seen by many as Number 10's favourite for the job, but currently occupied as Transport Minister for London.

She held the seat with an increased majority in 1997 and enjoys a high profile in the capital.
A recent MORI poll for BBC Newsroom South East and Greater London Radio put Ken Livingstone as the politician most Londoners thought would make a good mayor.
That support though, is not reflected by his party leadership, who remain wary of his Old Labour roots the Brent East MP wears on his sleeve.
Livingstone was the last leader of the former Greater London Council before it was abolished by the Thatcher government in 1986.
Has backed the government's plans for a return to strategic government for London, but has made no secret of the fact that he would like the new mayor and authority to have tax varying powers.

Patten has not said whether he would take the job, but he is the only one of the suggested contenders who's actually had experience of running a city. He was Hong Kong's last governor before the handover to China... a post that raised his profile, if not his popularity in Beijing.

The only black candidate to emerge so far, he did so with the reported tacit backing of the Prime Minister. Phillips was the first black president of the National Union of Students and now presents 'The London Programme' for LWT.
The Minister Without Portfolio, Peter Mandelson, was best man at his wedding, a fact which means support for him within the party may be polarised.
