BBC political editor Laura Kuenssberg was booed and hissed at as she asked Jeremy Corbyn a question after he made a pro-EU speech in London on Thursday.
The treatment she received came just 24 hours after a new Vice News documentary in which the Labour leader heavily criticised the corporation's coverage of his time in office.
There is not one story on any election anywhere in the UK that the BBC will not spin into a problem for me.
It is obsessive beyond belief. They are obsessed with trying to damage the leadership of the Labour party.
In what has been described as a hostile atmosphere at the Insitute of Engineering Technology, Corbyn told his supporters to quell their noise after several seconds so Kuenssberg could ask her question.

The treatment the journalist received was branded as "pathetic" by several commentators - as well as receiving criticism from several Labour MPs including Wes Streeting and Gloria De Piero.
Corbyn's reaction to the boos contrasted starkly with that given by Justin Trudeau, Canada's prime minister and fellow poster boy for the left, in a similar incident last year.
In the wake of the resignation of his campaign chief, the Liberal party leader faced questions about the controversy.
As his supporters jeered and heckled one journalist, Trudeau had a much more convincing response, interjecting:
Hey! We have respect for journalists in this country. They ask tough questions and they're supposed to.
