Definition of independent for the purposes of this question: source is not owned by a for-profit corporation, is not financially backed by any billionaire (either directly or via foundation or nonprofit organization) and is not financed by any national government (even if run without oversight).

Are you serious? The BBC are literally a government mouthpiece, with a subversive right-wing bias. When Labour is in power, they over-report every misdeed, and when the Tories are in power, they maybe raise an eyebrow as the country burns. The last BBC director was a major Tory who received a sizeable bribe from his party during his tenure.
