14 MI6 denies that Mr Litvinenko was a double agent working for Britain during his time in the FSB. The inquiry was told he became an adviser to the Secret Intelligence Service in 2003, after fleeing to Britain with his wife and son via Turkey in 2000. He was given an allowance and an encrypted mobile telephone and assigned a handler using the name Martin. One of the venues used by the two men was the Piccadilly branch of the bookseller Waterstones. On Oct 31, the day before he was poisoned, Mr Litvinenko met Martin in the store’s cafe. Martin drank coffee; his source chose hot chocolate and pastries. Mr Litvinenko’s last conversation with Martin was on Nov 19 as the Russian lay dying in hospital.
