Journalists and activists in Sri Lanka have accused the government of threats, intimidation, and violence against those who criticise the authorities.

It comes as the Commonwealth heads of government, who subscribe to freedom of expression in the Commonwealth Charter, are preparing to meet there.

The BBC's Fergal Keane reports on a newspaper at the centre of the claims, and the country's notorious white vans.
