Zohran Mamdani has won a resounding victory in the New York mayoral election, heralding in a new era for the city as he promises to be “Trump’s worst nightmare”.

"I know you're watching, turn the volume up," the 34-year-old socialist tells the president as he becomes the first Muslim mayor of New York City.

Mamdani will be the youngest New York mayor in a century, NBC News projects, after a rapid rise past Andrew Cuomo and other opponents.

Mamdani, a democratic socialist and state assemblymember, will make history as the first Muslim and South Asian person — as well as the youngest in over a century — to serve as New York City mayor.

Zohran Mamdani, the millennial socialist whose unabashedly left-wing campaign for Mayor of New York City unnerved many national Democrats but emboldened others, prevailed Tuesday as expected at the ballot box, installing him as leader of the nation’s largest city and a potentially powerful figure within a party looking for its next act.

NEW YORK (AP) — When he announced his run for mayor last October, Zohran Mamdani was a state lawmaker unknown to most New York City residents. But that was before the 34-year-old democratic socialist crashed the national political scene with a stunning upset over former New York Gov. Andrew Cuomo in June’s Democratic primary.

Zohran Mamdani defeated former Gov. Andrew Cuomo in a generational battle between Democrats in the New York City mayor's race.

New York’s mayor-elect Zohran Mamdani reportedly received a phone call from former US President Barack Obama last Saturday. But did Obama endorse Mamdani?

The president urged New York City voters to elect former Gov. Andrew Cuomo in Tuesday's mayoral election and threatened to withhold funding if Zohran Mamdani wins.
