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.

Gordon Corera reports.
