David Cameron has been warned by the Sri Lankan government not to quiz them over alleged war crimes in 2009.

The prime minister has rejected calls to boycott a Commonwealth summit in the country, saying he would use his visit to raise its human rights record but the Sri Lankans said he had no right to bring it up as he had not been invited on that basis.
