On March 14, 2018, British Prime Minister Theresa May expelled 23 Russian diplomats. That expulsion order was precipitated by the attempted murder of Sergei Skripal, who had defected from Russian intelligence to British intelligence, and Skripal’s daughter Yulia. That botched assassination attempt by Russia’s military intelligence arm known as GRU injured the Skripals, a police officer, and later, killed an innocent Briton who stumbled across the GRU nerve-agent device.

But who were the expelled diplomats?
