Russian ambassador to UK confirms expelled diplomats will leave on March 20, 2018.

The UK this accused Russian government of a chemical-weapons with attack on British soil targeting Sergei Skripal, a former double agent. Any evidence in support of the accusation has yet to be made public. British officials claim that the nerve agent Novichok used against Sripals was invented in the Soviet Union and that Kremlin was culpable either for carrying out the attack or for losing control of this weapon of mass destruction.
