Amnesty International is calling on people in Bolton to help stop violence against women.

The charity, which fights for victims of injustice across the world, made its plea after a poll revealed that more than a third of Britons believed a woman was partially responsible for being raped if she behaved flirtatiously.

On Saturday, the Bolton and Bury branch of Amnesty International will be conducting a survey in the Market Hall, Bolton, to explore ways of stopping violence against women.

Phil Newsham, branch secretary, said they would ask people a few questions, the findings of which would be sent to the Government in a bid to emphasise the importance of changing attitudes about rape.

He described the findings of last weeks poll as disturbing and said: "The poll also shows that more than a quarter of people said that a woman was partially or totally responsible for being raped if she was drunk."

Twenty-six per cent had the same opinion if a woman was wearing sexy or revealing clothing; and more than one in five held the same view if a woman had had many sexual partners.

"Clearly the number of women raped is not going to be reduced from the shockingly high level of an estimated 50,000 victims a year in this country until we change these ideas," he said.
