New York: Zohran Mamdani was elected mayor of New York City on Tuesday, capping a stunning ascent for the 34-year-old state lawmaker, who was set to become the city's most liberal mayor in generations.

In a victory for the Democratic party's progressive wing, Mamdani defeated former Gov. Andrew Cuomo and Republican Curtis Sliwa. Mamdani must now navigate the unending demands of America's biggest city and deliver on ambitious — sceptics say unrealistic — campaign promises.

Mamdani won the NYC Mayoral election, getting 948,202 votes (50.6 per cent), with 83 per cent of the votes in.

He had been the front-runner in the NYC Mayoral election for months and on Tuesday defeated Republican nominee Curtis Sliwa and political heavyweight former New York State Governor Andrew Cuomo, who ran as an independent candidate and received US President Donald Trump's endorsement only on the eve of the election.

Cuomo garnered 776,547 votes (41.3 per cent) while Sliwa got 137,030 votes.

With the victory, the democratic socialist will etch his place in history as the city's first Muslim mayor, the first of South Asian heritage and the first born in Africa. He will also become the city's youngest mayor in more than a century when he takes office on January 1.

Mamdani's unlikely rise gives credence to Democrats who have urged the party to embrace more progressive, left-wing candidates instead of rallying behind centrists in hopes of winning back swing voters who have abandoned the party.

He has already faced scrutiny from national Republicans, including President Donald Trump, who have eagerly cast him as a threat and the face of what they say is a more radical Democratic Party.

The contest drove the biggest turnout in a mayoral race in more than 50 years, with more than 2 million New Yorkers casting ballots, according to the city's Board of Elections.

Mamdani's grassroots campaign centered on affordability, and his charisma spoiled Cuomo's attempted political comeback. The former governor, who resigned four years ago following allegations of sexual harassment that he continues to deny, was dogged by his past throughout the race and was criticized for running a negative campaign.

There's also the question of how he will deal with Trump, who threatened to take over the city and to arrest and deport Mamdani if he won. Mamdani was born in Uganda, where he spent his early childhood, but was raised in New York City and became a US citizen in 2018.

Mamdani must now start building for his ambitious agenda.
