Re: The BBC used to be more independent.
"Ofcom received 1,868 complaints of political bias between 2014 and 2017, none of which were upheld. Since this is the only objective criteria we currently have for measuring it, the only conclusion we can make is that the BBC is indeed politically neutral."
Not necessarily. It is equally reasonable to assert that the bias at the BBC is the same as the bias at Ofcom, so Ofcom's people don't "see" the BBC bias (and therefore the complaint is incorrect).
