On Monday, British Prime Minister Theresa May said a chemical weapon developed under a secret Soviet program dubbed Novichok was used in the poisoning of Sergei Skripal. May demanded that Russia provide details of the program, saying otherwise London would consider the poisoning an attack directed by the Russian government.

“As soon as the rumors came up that the poisoning of Skripal involved a Russia-produced agent, which almost the entire English leadership has been fanning up, we sent an official request for access to this compound so that our experts could test it in accordance with the Chemical Weapons Convention [CWC],” Lavrov said. So far the request has been ignored by the British side, he added.
