President of the Cambodia National Rescue Party - Sam Rainsy

Sarah Montague speaks to the President of the Cambodia National Rescue Party, Sam Rainsy. The UN, US and Europe all say they are worried about what is going on in Cambodia. More than a dozen opposition figures are in prison, the party's vice president has not left their headquarters in four months for fear of being arrested, and the opposition leader Sam Rainsy fled the country to avoid jail. They want to replace Prime Minister Hun Sen, who has been in power for more than 30 years and whom they claim has rigged past elections. They have threatened mass demonstrations if the intimidation continues. But can their leader make a difference to life in Cambodia when he is in self-imposed exile in Europe?
