Ken Livingstone has failed to deliver any real improvements in Londoners' lives since becoming mayor two years ago, according to former Tory mayoral candidate Steve Norris.

Norris, who was this week sacked by Livingstone from the board of Transport for London, said: "I just find it very, very hard to agree with anything he is doing...He's more interested in picking fights with former colleagues than in showing how devolved government could work."
