Marina Litvinenko: 'The truth has finally been uncovered'
Alexander Litvinenko's widow Marina has said the "murderers and their paymasters have been unmasked" as she spoke outside the inquiry into her husband's death.
Russian dissident Mr Litvinenko, 43, drank tea containing a fatal dose of radioactive polonium during a meeting with suspects Dmitry Kovtun and Andrei Lugovoi in 2006.
Mrs Litvinenko said that "facts speak for themselves" and said her husband "was killed by agents of the Russian state". She said that it would not have happened without the "knowledge" of Russian President Vladimir Putin.
The Kremlin told the BBC it did not trust the inquiry.
