British PM to pay official visit to Moscow Sept. 11-12

British Prime Minister David Cameron will pay an official visit to Moscow on September 11-12 at the invitation of Russian President Dmitry Medvedev, the Kremlin said on Wednesday. \"Russian-British high-level talks will be held on September 12,\" the Kremlin said. Russian-British relations have been strained over a host of issues, including the controversial death of former KGB officer Alexander Litvinenko in London in 2006 and Russia\'s pressure on the British Council in 2007-2008. The issues also include Britain\'s criticism of Moscow after the Russian-Georgian military conflict in August 2008 and tit-for-tat diplomat expulsions. Russia has also accused Britain of acting as a refuge for fugitive Russian businessmen, including Boris Berezovsky. The countries currently cooperate on key international issues, but there has been no noticeable progress in the resolution of bilateral disputes.
