KGB 'try to poison man' in sushi bar

Scotland Yard is investigating the attempted murder of a top Russian defector poisoned by political enemies in London.

Alexander Litvinenko, an ex-KGB colonel who fled the current Russian regime to claim asylum in Britain, is under armed police guard in hospital.

Sources have confirmed that the Russian was taken suddenly and dangerously ill on November 1 while investigating the recent murder of dissident Russian journalist Anna Politkovskaya. Mr Litvinenko was poisoned following a clandestine meeting with an associate at a sushi bar in London's Piccadilly.
