Sri Lanka's ruling family are mingling with the Commonwealth's elite as they host this week's summit in Colombo. Yet some of them have been accused of war crimes. So who are the Rajapaksas?
President Rajapaksa has been president of Sri Lanka since 2005, having been elected with just over half the country's votes. Since then his popularity has grown, largely due to the fact that, within four years of having come to power, he had ended the Sri Lankan civil war and had crushed the Tamil Tigers movement.
