Russia link to Litvinenko death to be examined
An inquest into the death of the former Russian spy Alexander Litvinenko will examine claims that the Russian government was involved in his death.
Mr Litvinenko, a British citizen, died from polonium poisoning after having tea with two Russians at a central London hotel six years ago.
The prime suspect, Andrei Lugovoi, has been elected as a Russian MP, and Mr Litvinenko's widow Marina says she believes the Russian government was responsible.
