Cameron arrived on November 14 in Sri Lanka ahead of a Commonwealth summit which is set to be overshadowed by his historic visit to the island's former war zone. Cameron has come under fire from campaigners for not joining the leaders of Canada, India and Mauritius in boycotting the three-day meeting in protest at alleged war crimes committed in the final days of Sri Lanka's decades-long ethnic conflict.
