London mayoral candidates: Who are the runners and riders as Sadiq Khan stands for third term?
Meet the candidates taking on Sadiq Khan. For the first time, the election will be conducted using a "first past the post" system - where each voter chooses a single candidate, with the winner determined by simple majority.

The London mayoral elections are taking place on 2 May, with Labour's Sadiq Khan aiming to keep his role.
Mr Khan has been in post since 2016, when he took over from Boris Johnson, and is standing for an unprecedented third term in the capital.
The election is taking place alongside local elections across England and Wales.
For the first time, the election will be conducted using a "first past the post" system - where each voter chooses a single candidate, with the winner determined by simple majority.
Prior to a government rule change, the London mayoral elections used the supplementary vote system - where each voter chooses a first and second-preference candidate and the lowest supported person being eliminated until someone takes 50% of the vote.
Who is standing for London mayor?
Labour Party
Sadiq Khan
In December 2022, Mr Khan was chosen as Labour's candidate for the 2024 election after saying: "There's still so much more to do."
He said the race would be a "very tough election" and denied rumours he would be returning to Westminster, where he was the MP for Tooting for 11 years.
The mayor's first two terms have not been without controversy, and his expansion of the ULEZ (ultra-low emission zone) to all London boroughs in August 2023 is set to become a major battleground for the election.
Several Conservative-run outer London boroughs and home counties councils have taken Mr Khan to court over the expansion.
After confirming he will be standing, Mr Khan said voting him in again would "send a message to the Tories" about the current state of the economy.
He also criticised the fact a first-past-the-post system will be used for the first time in a London mayoral election, as well as the fact that voter ID will be required.
The two changes "appear deliberately designed to disenfranchise minority communities and disproportionately affect Labour votes", he said.
Conservative Party
Susan Hall
A London Assembly member since 2017 and Conservative leader of the assembly until recently, Susan Hall said she has a "common sense plan to fix our great city".
She regularly faced off against Mr Khan during mayor's question time. Ms Hall was chosen by London Conservative members, fending off competition from the likes of Paul Scully - a Boris Johnson ally and MP.
Ms Hall has proposed wide-ranging changes to the Met Police, saying it needs "root and branch reform", and told the Telegraph "basic rights" need to be addressed first as opposed to focusing on "roads [being] renamed".
She has also spent much of her time campaigning against the ULEZ expansion - saying she will scrap it on her first day in office if she wins.

Zoe Garbett
In February 2023, NHS worker Zoe Garbett was announced as the Green Party's candidate after winning the vote against Islington councillor Benali Hamdache and former MEP and Lambeth councillor Scott Ainslie.
The 35-year-old Hackney councillor came second in 2022's Hackney mayoral race and works in a non-clinical role for the NHS.
She said her focus will be on "addressing inequality and injustice" and said the London mayor must "do all within their power to make the city more affordable".
Ms Garbett has also promised to address "huge failings" in the Met Police.

Reform UK
Howard Cox
The founder of FairFuel UK, a campaign group against hydrocarbon oil duty increases, has been selected as the right-wing populist party's candidate and has promised to scrap the ULEZ altogether - not just Mr Khan's expansion.
The party was formerly the Brexit Party and its president is Nigel Farage, former leader of UKIP.
Mr Cox has called himself a "lifelong Conservative voter" who wanted to run, as "a vote for the Tories is a vote for Labour's Sadiq Khan".
As well as scrapping the ULEZ, he wants to get rid of low traffic neighbourhoods and 20mph zones.

Liberal Democrat
Rob Blackie
Mr Blackie, whose regular job is in digital marketing, has been an active member of the Lib Dems for more than two decades - including as director of research for then-leader Charles Kennedy during the Iraq War.
He has also stood as a candidate for the London Assembly, and was previously on the shortlist to be the party's candidate for mayor, but this is his first time competing for the role against other parties.
The policies he has advocated in the race include wanting police to stop "wasting time" on low-level drug offences and instead investigate sexual assaults.
Mr Blackie has also called for green priorities to be a focus.
