India rape: Politicians 'evade justice' say campaigners

Prime Minister David Cameron is making a three day visit to India next week.

Mr Cameron will be arriving in a country still traumatised by the gang rape of a Delhi student just before Christmas who later died of her injuries.

It set off weeks of protest over Indian attitudes towards women. But it has also prompted deeper questions in the world's largest democracy about how it runs itself, as many of its serving politicians are themselves accused of rape, murder and other serious crimes.
