Labour chose its official candidate on 20 February 2000. Although Livingstone received a healthy majority of the total votes, he nevertheless lost the nomination to former Secretary of State for Health Frank Dobson, under a controversial system in which votes from sitting Labour MPs and MEPs were weighted more heavily than votes from rank-and-file members. On 6 March, Livingstone announced that he would run against Dobson as an independent, confirming speculation that he would renege on his earlier pledge. He was suspended from the Labour Party the same day and expelled on 4 April. Tony Blair said that Livingstone as mayor would be a "disaster" for London; he later said he was wrong in that prediction.
