London: A coroner overseeing a British inquest into the 2006 poisoning death of Alexander Litvinenko has requested that a separate public inquiry be held so that crucial evidence can be scrutinised.
The request announced on Wednesday comes after a ruling last month that sensitive evidence, including documents relating to Russia`s alleged role in the former agent turned Kremlin critic`s death, must be excluded from the existing inquest on national security grounds.
Litvinenko`s widow believes a separate inquiry will clarify what happened to Litvinenko, who died in 2006 after drinking tea laced with the radioactive isotope polonium-210 at a London hotel.
Coroner Robert Owen made the request to Justice Secretary Christopher Grayling.
Inquests are conducted in Britain to establish the circumstances surrounding unexpected or violent deaths.
