In other democratic news, RT has got into trouble with the British media watchdog agency Ofcom, which has started an inquiry about the channel not being objective and impartial enough. It may (and probably will) result in RT being officially banned from the airwaves in the United Kingdom.
It's far more likely they will just be fined. In 2013 they were hit for bias over broadcasts relating the Syrian conflict. You can read the complete report
here (starts page 6, goes on for a while). It boils down to them showing a propaganda video from Rossiya 24 about how horrific the Syrian opposition is and then trying (unsuccessfully) to argue it didn't need to be unbiased.
British journalism tends towards the confrontational and aggressive. Interviewers are expected to challenge the statements of the interviewees and bring forwards opposition views, even when those views are objectionable or marginal. Every report is expected to contain some due representation of opposing arguments or at least representation and comment from other policy views. That includes documentary or commentary pieces in nearly all cases; hell, most effective persuasive documentaries start with the opposition position and then deconstruct it throughout the program. RT seemed to believe this doesn't apply to them. Note that despite this not being their first offence they were only called to a meeting and didn't immediately face any sanction.
The only way I can think of them completely losing their license would be if it went the Press TV route. They lost their license because, despite their license being for operations in the UK,
their editorial decisions were made directly from Tehran. Even their ignoring a previous fine wasn't enough for them to be removed.
