Theresa May has accused Russia of meddling in elections and planting fake stories in the media in an extraordinary attack on its attempts to “weaponise information” in order to sow discord in the west.
The prime minister spoke out against “the scale and nature” of Russia’s actions during an address at the lord mayor’s banquet, saying it was “threatening the international order on which we all depend”.
Listing Russia’s attempts to undermine western institutions in recent years, she said: “I have a very simple message for Russia. We know what you are doing. And you will not succeed. Because you underestimate the resilience of our democracies, the enduring attraction of free and open societies, and the commitment of western nations to the alliances that bind us.
“The UK will do what is necessary to protect ourselves, and work with our allies to do likewise.”
Her speech is a serious escalation of the UK’s warnings about Russia as Boris Johnson, the foreign secretary, prepares to visit Moscow before the end of the year as part of a strategy of cautious engagement with Vladimir Putin’s administration.
Since Russia’s annexation of Crimea from Ukraine, May said Russia had “fomented conflict in the Donbass [eastern Ukraine], repeatedly violated the national airspace of several European countries, and mounted a sustained campaign of cyber-espionage and disruption”.
