Next up on Asia Focus. We look at the poisoning of a Russian former spy on UK soil. 

British police have found where the former spy and his daughter first came into contact with the nerve agent. The front door of their house in England. The pair were found collapsed on a bench on March 4th and remain in critical condition. The UK said Russia is behind the attempted assassination, linking the alleged military-grade nerve toxin to a Soviet-era project. It led to the expulsion of Russian diplomats from many western countries. Russia denied any involvement, and is conducting its own investigation into the attack.
