Six on Labour Party mayor shortlist
Six candidates will fight it out to be Labour's candidate in next year's London mayoral election, the party announced.
All of the City Hall hopefuls who secured the minimum required nominations from constituency parties in the capital survived an interview process to make it onto the ballot paper.
The frontrunners in the race to wrest back the influential post for Labour after eight years with Tory Boris Johnson at the helm are ex-culture secretary Dame Tessa Jowell and MP Sadiq Khan, who quit as shadow justice secretary to concentrate on the mayoral contest.
Others on the list are MPs David Lammy, Diane Abbott and Gareth Thomas and journalist Christian Wolmar.
But the bookies' favourite to succeed Mr Johnson is Conservative MP and environmentalist Zac Goldsmith - who has declared that he will stand so long as he receives the approval of his Richmond Park constituents in a mini-referendum.
Voting, on a one-member-one-vote basis, will be open to Labour members and anyone who pays £3 to be a registered supporter or signs up as an affiliate supporter by August 12 - with the victor announced alongside the party's new leader and deputy over the weekend of September 12/13.
Acting leader Harriet Harman said: "The mayor has let down London for too long. We need a Labour mayor in City Hall to stand up for the interests of all Londoners, from Richmond to Redbridge and from Barnet to Bromley.
"But it won't just be Labour's members who choose our candidate. As with our leader and deputy leader elections, we will let the public in.
"Hustings events will be open to the public to come and hear from the candidates, and anybody resident in London who supports the Labour Party can register to vote for who they want to see as the next Labour mayor.
"Labour's mayoral candidate will lead the fightback against the Tories on behalf of Londoners. Who we choose is crucial - and a decision that I want everybody to be involved in making."
Dame Tessa led the way in nominations from constituency parties - who had two votes each, one of which had to be for a female candidate - with 63, while Mr Khan garnered 42, Mr Lammy 15, Ms Abbott eight, Mr Thomas six and Mr Wolmar six - one more than the minimum number required.
Nominations from trade unions and other affiliated organisations went mostly to Mr Khan with seven while Dame Tessa received two and Mr Thomas one.
Mr Khan said: "I'm very pleased to have been placed on the shortlist to be the Labour Party candidate for Mayor of London.
"I am grateful to all the local Labour parties, trade unions and affiliated organisations who nominated me.
"I will now spend every day until the polls close convincing Londoners taking part in the selection process that I am worthy of their trust and that I can deliver the victory in 2016 we all want".
