Britain will oppose Sri Lanka hosting the next Commonwealth summit because of concerns over its conduct of the war against Tamil fighters and its treatment of refugees, a government source said on Friday, according to Reuters. Leaders of the group of 53 nations, mainly former British colonies, meet in Trinidad and Tobago from Friday and one of the issues to be discussed is who will host the next summit in 2011. Sri Lanka is one of a number of countries bidding to host the next summit. British Prime Minister Gordon Brown"s opposition to Sri Lanka getting the honour could cause friction at the meeting. "The prime minister has real concerns about Sri Lanka"s bid. We simply cannot be in a position where Sri Lanka -- whose actions earlier this year had a huge impact on civilians, leading to thousands of displaced people without proper humanitarian access -- is seen to be rewarded for its actions," a British government source said.
