Is this someone describing the media campaign against Jeremy Corbyn? No, it's Seumas Milne's account of the campaign against the miners' union in "The Enemy Within"—an account that's well worth rereading in the light of recent events. 
A high-profile documentary slot and a nominally progressive newspaper lending its support to a discredited propaganda campaign against an insurgent left-wing movement? Surely that could never happen again?
Reminded of something Benn said about the difference between Thatcher and Scargill: her faction threw her under the bus at the first sign of difficulty, his didn't. I don't suppose pundits will understand why the left won't hang Corbyn out to dry; it's what they'd do, after all.
