Alexander Litvinenko death: Inquiry to be held
A public inquiry will be held into the death of the Russian dissident Alexander Litvinenko, the UK Home Secretary Theresa May has announced.
Mr Litvinenko, a former KGB officer who became a British citizen, died in 2006 in a London hospital after he was poisoned with radioactive polonium.
The investigation will examine whether the Russian state was behind his death.
