Sadiq Khan, a practicing Muslim and Labour Party politician, has been elected mayor of London, marking a political milestone in the Western world.
Londoners voted in Khan, 45, as the first Muslim mayor of a major Western capital city. He will take office in a metropolis where his fellow Muslims comprise about 12% of the population.
His victory followed an unusually bitter campaign against Conservative candidate Zac Goldsmith, the son of a billionaire, in which race and religion have proven ugly flashpoints.
The London-born son of Pakistani immigrants, Khan grew up with his six brothers and sister in a three-bedroom, public housing apartment.
He studied law, became a university lecturer and the chairman of a civil liberties group, and was elected to Parliament in 2005.
Affordable housing in a city increasingly drawing the super-rich, aging infrastructure and transportation are top issues facing the new mayor.
Khan is replacing incumbent Boris Johnson, a colorful and popular figure who took office in 2008 and was a rare Conservative mayor in the Labour-leaning British capital.
Johnson is leading the campaign for Britain to leave the European Union at a referendum on June 23. He is clashing with Prime Minister David Cameron, who is in favor of the United Kingdom remaining.
