Sergei Skripal, the Russian ex-spy who was left in a critical condition by a nerve agent attack in Salisbury, UK for more than two months has been discharged from the Salisbury District Hospital .

The 66-year-old Skripal, a former colonel in Russia’s military intelligence who betrayed dozens of agents to defect to Britain and his daughter, Yulia were found unconscious on a bench in Salisbury on March 4.

Britain’s accusations that Russia was behind the attack on the Skripals led to a Russia versus West crisis in which Western governments including the United States expelled more than a hundred Russian diplomats even as Kremlin denied any involvement in the poisoning and retaliated.

Britain and international chemical weapons inspectors said the Skripals were poisoned with Novichok, a deadly group of nerve agents developed by the Soviet military in the 1970s and 1980s.

British police say they will however not give any details of the Skripals’ new security arrangements in the interest of their safety and on Friday, neither they nor the management of the hospital gave any details of their whereabouts.
