Angelina Jolie was in London yesterday to meet British Foreign Secretary William Hague and to give a speech giving her backing to a new government campaign to fight sexual violence in conflict zones.

Looking radiant and professional in a chic black dress, the actress gave an emotional speech to ministers in London during which she emphasised the need to give justice to the victims of rape.

Jolie, who is a Special Envoy for the United Nations' High Commissioner on Refugees, gave her views on the subject before attending a screening of her directorial debut, In The Land Of Blood And Honey.

British Foreign Minister William Hague praised Jolie for using her movie to highlight the atrocities committed during the Balkan conflict and gave some shocking figures about the extent of rape and sexual violence that took place against women and children.

He said: 'I was shocked when I learned that only 30 people have been convicted so far for the up to 50,000 rapes committed during the war in Bosnia in the 1990s. And there are chilling reports of rape in Syria today along with the murder, torture and repression of thousands of innocent civilians.
