Emma Watson's back with a powerful gender equality speech at Davos

Emma Watson has delivered a powerful follow-up to her much-lauded speech on gender equality at the United Nations last September.

In her role as a goodwill ambassador for UN Women, the actress announced a year-long initiative calling for new leadership, especially from universities and companies, to end the "persisting inequalities faced by women and girls globally".

Impact 10x10x10 Initiative is being launched as part of HeForShe, which was launched at the UN General Assembly last year in New York in a bid to get more men involved in helping fight for equality.
