Tamil exiles in Britain voiced anger yesterday as David Cameron's motorcade purred through their homeland between photocalls with their persecutors.

Hundreds of demonstrators clutching photos of missing relatives thronged the PM's car as he drove through the northern city of Jaffna to a Commonwealth nations' conference in Sri Lanka.

Mr Cameron (right), who visited a local library, a newspaper's offices and a Tamil refugee camp, promised "a frank exchange of views" with president Mahinda Rajapaksa regarding the killings and disappearances.
