The footage, reportedly from 2014, shows Corbyn, flanked by Labour candidates Catherine West and David Lammy, saying: "I am no fan of NATO, indeed I wish NATO didn't exist. I am no fan of Western military alliances, indeed I wish they didn't exist", The Daily Mail reported Tuesday.
Last month, Corbyn reportedly refused to call the NATO alliance a great military success during an interview. Asked if he agreed with the chief of defence staff, Nick Carter, on the latter's description of NATO as being the "most successful military alliance in history", Corbyn replied: "I'm not sure I'd define it as that", according to the Daily Mail.
According to the media report, the Tories hope to use what they claim is Labour's lack of support for the UK military as the centre of their political campaign this week.
Corbyn, in his first major foreign policy speech on Sunday, remarked that he wanted the next UK government to push NATO to soften its stance on Russia, and stop leaning on the United States for support. If Labour wins the 12 December election, the party will "work for the alliance to reduce tensions in Europe and beyond", Corbyn said, which may be the focus of the next week’s NATO summit in London.
