The Conservative Party has been forced to remove a vicious Jeremy Corbyn attack video after a copyright claim was made against it.
It's thought that footage used by the Tories taken at a conference last year prompted a complaint from the copyright holder.
The video has been removed from Youtube
YouTube user Adrian Cousins appears to have made the complaint relating to footage taken at the Dangerous Times festival in 2014.
Corbyn told the conference he believed defence alliance NATO should be scrapped.
It comes after the Russian Embassy in London tweeted its critique of David Cameron's contention that Corbyn and the Labour Party now present a "threat to national security".
Black-and-white, grainy footage, Corbyn sounding angry: the Conservative Party spells out the "facts" as it sees it.
The grainy footage of Jeremy Corbyn in the 'attack video'
The rapid nature of the Conservative's response to Corbyn's election echoes that of American politics where 'attack advertising' is commonplace.
Conservatives deliberately said very little about the left-winger during the leadership election campaign, allowing the candidates to criticise each other. But they are now no longer keeping their powder dry. Defence Secretary Michael Fallon was first out of the traps to offer an almost breathless warning.
"Labour are now a serious risk to our nation's security, our economy's security and your family's security. Whether it's weakening our defences, raising taxes on jobs and earnings, racking up more debt and welfare or driving up the cost of living by printing money – Jeremy Corbyn's Labour Party will hurt working people."
However, many people online promptly mocked the Tories' "security" mantra.
The Conservative Party is yet to respond to a request for comment.
