Inaugural London mayoral election
The 2000 London mayoral election was held on 4 May 2000 to elect the Mayor of London. It was the first election to the office established that year; the idea of a mayor of a Greater London Authority (GLA) had been included in Labour's 1997 election manifesto, and after their election a referendum in London was scheduled for May 1998, in which there was a 72% yes vote with a 34% turnout.
Electoral system.
The election used a supplementary vote system, in which voters express a first and a second preference for candidates. 
This means that the winning candidate has the support of a majority of voters who expressed a preference among the top two.
Candidate selection.
Labour.
With the first mayoral election scheduled for May 2000, Ken Livingstone stated his intention to stand as a potential Labour candidate for the position in March 1998. Tony Blair did not want Livingstone as London Mayor, claiming the latter was one of those who "almost knocked [the party] over the edge of the cliff into extinction" during the 1980s. He and the Labour spin doctors organised a campaign against Livingstone to ensure that he was not selected, with Alastair Campbell and Sally Morgan unsuccessfully attempting to get Oona King to denounce Livingstone. They failed to convince Mo Mowlam to stand for the mayorship, and instead encouraged the reluctant Frank Dobson to stand. Recognising that a 'one member, one vote' election within the London Labour Party would probably see Livingstone selected over Dobson, Blair ensured that a third of the votes would come from the rank-and-file members, a third from the trades unions, and a third from Labour MPs and MEPs, the latter two of which he could pressure into voting for his own preferred candidate, something that Dobson was deeply uncomfortable with.
Information on the Blairite campaign against Livingstone became public, costing Dobson much support; nevertheless, while Livingstone won amongst party members (60% to Dobson's 40%) and among affiliated unions (72% to Dobson's 28%, a more than 2:1 vote), Dobson's landslide victory (173:27 in ratio) amongst MPs, MEPS and GLA candidates saw him win narrowly overall: forming a simple electoral college outcome of 51.5% to 48.5%. Livingstone proclaimed Dobson to be "a tainted candidate" and stated his intention to run for the Mayoralty as an independent candidate. Aware that this would result in his expulsion from Labour, he publicly stated that "I have been forced to choose between the party I love and upholding the democratic rights of Londoners." 
Conservatives.
Steve Norris had lost the original selection ballot for Conservative candidate to Jeffrey Archer, but Archer stood down as a candidate when a newspaper printed a story accusing him of committing perjury during a 1987 libel trial (he was later convicted and imprisoned).
