Sadiq Khan has been named London's new mayor after winning 1,310,143 votes to Zac Goldsmith's 994,614.
Here are the issues and top priorities he has promised in his manifesto for the capital.
Khan promises to make London safer by restoring neighbourhood policing, and tackling gangs, knife crime and extremism.
He said he will freeze travel costs for four years, and wants to introduce a one-hour bus "hopper" ticket.
Khan has said he will build thousands more homes for Londoners each year. He wants half of new properties to be affordable and says he will get a better deal for renters.
He has said he will be the "most pro-business mayor yet", and will work in partnership with industry to deliver on skills, infrastructure and growth.
Khan has promised to restore the capital to safe and legal levels. As well as making travel greener, he wants to pedestrianise Oxford Street and protect the Green Belt.
The new mayor has promised to work with employers to make London a living wage city.
He has committed to challenging the gender pay gap, and says he will deliver ways to support women to break the glass ceiling while removing barriers to their success.
He plans to introduce more segregated cycle routes, promises to take action on dangerous junctions and will make lorries on the capital's roads safer.
Khan has pledged to set up "Skills for Londoners", to ensure all residents have the opportunity to train and gain skills in areas that are lacking within the economy.
He has promised to make the city a fairer and more tolerant place, in which all people can prosper and live free from prejudice.
