Boris Johnson

Britain's foreign secretary said yesterday that the trail of blame for the poisoning of a former spy "leads inexorably to the Kremlin", after a Russian envoy suggested the nerve agent involved could have come from a UK lab. Foreign Secretary Boris Johnson said Britain has evidence that Russia has been stockpiling nerve agents like the one used against Sergei Skripal and his daughter Yulia. Johnson told the BBC officials from the Netherlands-based Organization for the Prohibition of Chemical Weapons would arrive in Britain on Monday to take samples of the nerve agent used to poison the Skripals.
