Emma Watson has been named a UN Women Goodwill Ambassador.

The actress said it was "truly humbling" be join the section of the United Nations organisation dedicated to gender equality.

The 24-year-old Harry Potter star said in a statement: "Being asked to serve as [a] UN Women's Goodwill Ambassador is truly humbling.

"The chance to make a real difference is not an opportunity that everyone is given and is one I have no intention of taking lightly.

"Women's rights are something so inextricably linked with who I am, so deeply personal and rooted in my life, that I can't imagine an opportunity more exciting.

"I still have so much to learn, but as I progress I hope to bring more of my individual knowledge, experience and awareness to this role."

Phumzile Mlambo-Ngcuka, the Under-Secretary-General and Executive Director of UN Women said: "The engagement of young people is critical for the advancement of gender equality in the 21st century, and I am convinced that Emma's intellect and passion will enable UN Women's messages to reach the hearts and minds of young people globally."

Watson previously worked with the UN promoting girls' education in countries such as Bangladesh and Zambia before taking up this role.
