A key ally of Jeremy Corbyn is speaking at a celebration for the Russian revolution this weekend.

Andrew Murray, a senior figure in the Unite union, is due to speak at a conference organised by the “Russian Revolution Centenary Committee”.

Other figures close to Corbyn set to speak include Asleft leader Tosh McDonald, who shared a platform with the Labour leader at last year’s Durham Miners’ Gala.

Aleida Guevara, the daughter of Cuban revolutionary Che Guevara, will speak alongside Cuban ambassador Teresita Vicente de Sotalongo at the event.

Mr Murray is chief of staff to Unite leader Len McCluskey, who is close to Mr Corbyn. Unite donates millions of pounds to the party every year.

Other speakers include Adrian Weir, an assistant chief of staff at Unite and a historian of the Labour movement, and Vyacheslav Tetekin, a former Russian MP.

The sold out one day event will give attendees “an introduction to the Russian revolution” and “the impact of Russian revolutionary politics on British society and the labour movement”.

Speakers will also discuss “international perspectives on the contemporary relevance of the Russian revolution”.

Philip Davies, a Conservative MP, said: “People can know that if they elect Mr Corbyn as Prime Minister he is backed by communists. I am not sure that is what the British people want in their heart of hearts.”
