Mariella Frostrup at Cheltenham with Hillary Clinton, who questioned Wikileaks’s impartiality, saying it never published “anything negative about Russia or Putin”

Hillary Clinton claimed yesterday that Wikileaks was an arm of Russian intelligence and that a new Cold War was descending on Europe through the weaponising of information.

The former US secretary of state said that the Kremlin was using the internet to foment trouble, boost the “ripples of right-wing nationalism and populism” and break up the European Union and Nato. Britain too, she said, was in danger from the Russian state’s propaganda machine as it embedded itself in the country.

She cited advertisements placed on the London Underground in recent days by the state-financed television channel Russia Today, which mock claims that it is involved in disinformation campaigns. It uses slogans such as: “Missed the train? Lost a vote? Blame it on us!”
