Sadiq Aman Khan (; born 8 October 1970) is a British politician who has served as Mayor of London since 2016.
He was previously the Member of Parliament (MP) for Tooting from 2005 until 2016.
A member of the Labour Party, Khan is on the party's soft left and has been ideologically characterised as a social democrat.
Born in Tooting, South London, to a working-class British Pakistani family, Khan earned a law degree from the University of North London.
He subsequently worked as a solicitor specialising in human rights issues and chaired the Liberty advocacy group for three years.
Joining the Labour Party, Khan was a Councillor for the London Borough of Wandsworth from 1994 to 2006 before being elected MP for Tooting at the 2005 general election.
Under Labour Prime Minister Gordon Brown, Khan was appointed Minister of State for Communities in 2008, later becoming Minister of State for Transport.
A key ally of the next Labour leader, Ed Miliband, he served in Miliband's Shadow Cabinet as Shadow Secretary of State for Justice, Shadow Lord Chancellor and Shadow Minister for London.
Khan was elected Mayor of London at the 2016 mayoral election, defeating Conservative Party rival Zac Goldsmith and then resigning as an MP.
In office, he introduced reforms to limit charges on London's public transport, backed expansion at London City Airport and Gatwick Airport, and focused on uniting the city's varied communities.
He was a vocal supporter of the unsuccessful Britain Stronger in Europe campaign to retain UK membership of the European Union.
As well as having a strained relationship with Labour leader Jeremy Corbyn, whose socialist platform Khan thought unelectable, he attracted international attention for his Twitter arguments with United States President Donald Trump.
He has been included in the Time 100 list of most influential people in the world.
Khan has been praised for promoting mutual tolerance among London's varied communities and has received various awards.
