Mamdani says he's a democratic socialist. What does that mean?

Zohran Mamdani, 34, has branded himself as a democratic socialist since 2020 when he first launched himself into the political spotlight and ran for New York state assembly.

Now, elected as New York City's first Muslim mayor and the youngest to lead America's most populous city in more than a century, he's embracing socialism more than ever.

President Donald Trump and other Republicans have attacked his political label and claimed Mamdani to be a communist.

The BBC's Nomia Iqbal looks at the meaning behind democratic socialism and what it means for New York.
