Mamdani: 'Last night we made history'
"Good morning New York, last night we made history," Zohran Mamdani says as he starts his news conference.
"I'm so proud to be standing here today as the mayor-elect of the greatest city in the world."
Mamdani says he will "work every day to honour the trust that I now hold".
"The poetry of campaigning may have come to a close last night at 9pm, but the beautiful prose of governing has only just begun," he says.
"The hard work of improving New Yorkers' lives starts now."
Mamdani - who will be the first Muslim, first South Asian, and youngest person in a century to serve as the famous city's mayor - used a victory speech to throw down the gauntlet to Donald Trump last night.
Mamdani said: "If anyone can show a nation betrayed by Donald Trump how to defeat him, it is the city that gave rise to him.
"This is not only how we stop Trump. It's how we stop the next one. So Donald Trump, since I know you're watching, I have four words for you: 'Turn the volume up'."
