The editor-in-chief of RT, formerly Russia Today, has threatened legal action against critics after a backlash to her comments proposing a nuclear strike on Siberia. ‘Slanderers get ready’, Margarita Simonyan wrote on her Telegram channel, announcing that she had filed a defamation complaint against parliamentary aide Nikolai Korolev and warning of action against others. The often-controversial executive, among the most powerful in Russian media, has drawn criticism over a bizarre video monologue in which she appeared to propose a nuclear detonation in Russia as a deterrent against the West. The video triggered an avalanche of criticism from pundits and politicians. Mr Korolev said, ‘Such statements are a violation of the legislation of the Russian Federation, not to mention the wildness and absurdity’. Other critics noted that the history of Soviet nuclear tests in Siberia has left a legacy of contamination. The Kremlin moved to distance itself from Ms Simonyan, who has a close relationship with Vladimir Putin.
