With defeat at the polls Ken Livingstone, a colourful political figure for over 40 years, has stepped down.
In an interview with ITV News Boris Johnson appeared to avoid answering questions about his Party's recent troubles and his own popularity.
Boris Johnson and Ken Livingstone have been involved in an angry confrontation in a lift at a London radio station.
Former London Mayor Ken Livingstone has paid tribute to RMT union leader Bob Crow, who has died suddenly:

Today, protests will be staged across the country against cost-cutting on the railways.
The Campaign for Better Transport (CBT) picked out three villains and three heroes of the last 50 years of the railways.
The villains were:
Dr Richard Beeching; author of the report which led to the axing of many railway stations and train routes.
Tom Fraser, minister for transport for 1964-65 for ensuring the cuts went ahead.
Sir Alfred Sherman, co-founder of Centre for Policy Studies, "for actively promoting converting railways to roads".
The Heroes were:
Barbara Castle, transport minister from 1965 to 1968, for giving large urban areas control of their rail systems.
Peter Parker, British Rail chairman 1977 to 1983, for restoring the reputation and pride of the railways.
The former Mayor of London Ken Livingstone has called Hugo Chavez "a friend and comrade":
K: Hugo Chavez showed there is an alternative to neo-liberalism and colonialism in Venezuela and worldwide. He was a friend & comrade #RIP
K: The best tribute for Hugo Chavez is to redouble our efforts for a world free of exploitation and colonialism #RIP
Ken Livingstone hit out at Boris Johnson this morning, describing him as a 'do-nothing Mayor'. He said: "With the exception of this rather silly little cable car there's nothing else he has started. If we have another four years like that then by the end of this decade London will be insufferable."
The race for the London mayoral election is still very close, with the Conservative candidate Boris Johnson ahead of Labour's Ken Livingstone by just four percentage points.
Voting is now complete in all but four of the 14 London constituencies.
There is full coverage of the race on our ITV London site.
Tony Travers, a local government expert from the London School if Economics, says it's looking even closer for the mayoral election.
In the previous run-offs, second preference votes haven't altered the outcome. Mr Travers thinks this time round they could.
If Siobhan Benita has taken votes from Ken Livingstone, Ken could win her second votes.
The race isn't over yet.
