LONDON — British officials say Prime Minister David Cameron may hold the first meeting for four years between a U.K. official and Russia's Vladimir Putin next week. The officials, who requested anonymity because they weren't authorized to discuss Cameron's plans in advance, said Thursday he will travel to Moscow to help improve fragile ties between the two nations. Russia President Dmitry Medvedev's office has confirmed he will meet with Cameron next Monday. Cameron is also expected to meet with Prime Minster Putin — the first talks between the ex-president and a British official since he met with Tony Blair in June 2007. Ties soured over Russia's refusal to hand over a suspect in the 2006 poisoning death in London of Russian dissident Alexander Litvinenko.
