Newly elected mayor Sadiq Khan said he "can't quite believe the last 24 hours" as he was sworn in at Southwark Cathedral.
Introduced by Doreen Lawrence, applause erupted as he opened by saying: "My name is Sadiq Khan and I'm the mayor of London."
I'm determined to lead the most transparent, engaged and accessible administration London has ever seen, and represent every single community and every single part of our city as mayor for all Londoners.
I promise you that I’ll always do everything in my power to make our city better.
Doreen Lawrence, the mother of teenager Stephen Lawrence who was murdered in 1993, has hailed the election of Sadiq Khan as mayor.
Describing today as a "glorious day" as she introduced him for his signing in at Southwark Cathedral, she added:
I never imagined in my lifetime I could have a mayor of London from an ethnic minority background. It is an amazing sign of how far our city has come.
London is a city that not only tolerates but celebrates diversity.
A city that’s chosen unity over division and hope over fear. A city that’s chosen a mayor for all Londoners.
Southwark Cathedral is the setting for Sadiq Khan's singing in as the new mayor of London, with politicians and even celebrities out in force.
Newly elected London mayor Sadiq Khan has left for his first day in his new job pledging to be a "mayor for all Londoners".
Saying he was "tired" after weeks of campaigning and a result which came after midnight, he told reporters outside his home his priority was "to try to get to the office".
I look forward to working with everyone to make sure I can be a mayor for all Londoners.
An announcement on who will be the new Mayor of London will not be made until midnight at the earliest.
The delay has been blamed on 'small discrepancies in the count'. Labour's Sadiq Khan appears on course to break the Conservatives' eight-year hold on the London mayoralty, after a live count of votes indicated a clear lead.
The returning officer is currently updating candidates and agents.
There were some small discrepancies with regard to the mayoral figures and we have to take the time to check them.
We're doing the checking in conjunction with the Electoral Commission.
We have to take the time to resolve these issues. We are working towards a declaration at midnight. I apologise.
Before the final declaration on Friday, the Conservative candidate looked set to lose the City Hall race to Labour's Sadiq Khan.Read the full story ›
Zac Goldsmith's sister has joined the chorus of criticism over the way his campaign was run. On Twitter, Jemima said:
Sad that Zac's campaign did not reflect who I know him to be- an eco friendly, independent- minded politician with integrity.
She went on to congratulate Sadiq Khan for his apparent victory.
Labour leader Jeremy Corbyn has hailed Sadiq Khan's apparent victory in the London mayoral election, tweeting:
The Tooting MP has been the frontrunner in the counting process ahead of Tory challenger Zac Goldsmith, according to first preference votes collated using an electronic system.
An official announcement is expected shortly.
