Britain has appointed a senior judge to conduct an inquest into the death of Russian dissident Aleksander Litvinenko, who was poisoned with polonium in London in 2006.
High Court Judge Sir Robert Owen will hold a pre-inquest review in public on September 20.
Inquests are fact-finding inquiries held under British law to examine sudden, violent, or unexplained deaths.
They are not trials and do not apportion criminal or civil liability.
British police have identified Andrei Lugovoi, a former FSB security agent, as a suspect in the murder.
Litvinenko, a spy turned exiled Kremlin critic, died on November 23, 2006, just over three weeks after drinking tea reportedly laced with highly radioactive Polonium-210 at a London hotel.
