Proof that Russia was involved in spy Litvinenko's death?

                                                  


I'll background the story first, for the sake of those who haven't been following the story of this story. In November 2006, a  former Russian top security agent/spy, Alexander Litvinenko died in London. He also worked for the KGB, the world's largest spy and state-security machine, involved in all aspects of life of everyday people in the Soviet Union. Autopsy reports showed that he had been poisoned some 3 weeks earlier at a meeting in the Mayfair area of London with radioactive polonium 210, which is hard to detect. Before he died, he had accused  Vladimir Putin, the President of Russia, of killing him. He had been granted political asylum in Britain based on the sensitive nature of his job.




His widow, Marina, never let the case die down. Mrs Litvinenko applied to the NSA (National Security Agency) to disclose telephone intercepts, and that “all information” should be disclosed to Sir Robert Owen, a former high court judge who will be handling the new findings in court from next week.

                                   

 In a tape that has just been released,  American spies secretly intercepted communications between those involved in the murder of Alexander Litvinenko and provided the key evidence that he was killed in a Russian-backed “state execution”.
