ambassador said: “Corbyn's first address to Parliament has shown that this man has also effectively changed the format of parliamentary discussion by appealing to concerns voiced by the citizenry via the internet.
“Naturally, the austerity policy has been challenged first off. Equally, full display is now given to alternatives in foreign and defence policy reflecting the views of Jeremy Corbyn, which he has been open about and, quite naturally, made part of his democratic mandate. Those include opposition to military interventions of the West, support for the UK’s nuclear disarmament, conviction that NATO has outstayed its raison d'etre with the end of the Cold War, just to name a few.”
In the days after Mr Corbyn’s election Mr Cameron said: “The Labour Party is now a threat to our national security, our economic security and your family's security.”
Those comments have since been echoed by Michael Fallon, the Defence Secretary, and a series of former military commanders.
“David Cameron said on Twitter that Jeremy Corbyn posed a threat to Britain's national security, economic security and the security of just about every British family,” Mr Yakovenko said. “As media reports suggest, these messages constitute the Conservative government's strategy to counter the threat posed by Jeremy Corbyn and his mandate.”
In a rare attack on a British head of state by a foreign ambassador, he described the Prime Minister's remarks as "such a flagrant approach to the results of an absolutely democratic process".
He went on: "I agree with those political observers, who believe that this country in on the verge of a historic shift, which is imminent not only in Britain, but in the West as a whole. Essentially, this is a result of moral and intellectual decline of political elites, who in deed, if not in word, have drawn the wrong 'end of history' conclusions from the end of the Cold War: there are no alternatives to neo-liberal policies, the market will sort it all out automatically etc."
Mr Corbyn’s victory has also been praised by Argentinian president Cristina Kirchner, who said Mr Corbyn wants open dialogue over the Falkland Islands.
“Hope has triumphed," she said. “He has actively accompanied the international community in their call for dialogue between Great Britain and Argentina over the Falklands question."
