Sex and the City star Cynthia Nixon runs for New York governor

Sex and the City actress Cynthia Nixon has announced she's running for New York City governor.

Rumours have been swirling for a while that the 51-year-old actress, who played Miranda in the hit franchise, would run against current governor, Andrew Cuomo.

Nixon confirmed it today via a video posted to her Twitter page.

"New York is where I was raised and where I'm raising my kids," she says in the video, which shows her daily life in NYC with wife, Christine, and son Charlie.

"I'm a proud public school graduate, and a prouder public school parent. I was given chances I just don't see for New York's kids today."

She goes on to say that New York's leaders are letting down the city's residents, pointing out problems with healthcare and the New York subway line.

"Half the kids in our upstate cities live below the poverty line. How did we let this happen?" she says.

"I love New York - I've never wanted to live anywhere else - but something has to change."

Nixon starred in the HBO series about a group of New York women from 1998 to 2004, as well as the following two films.

It was announced last year there would be no third movie in the Sex and the City franchise after high-profile disputes between the main actresses in the series.
