Everyone can agree BBC has an agenda. But it usually looks like no one can agree what that agenda actually is.

FWIW there's a new Director-general: Matt Brittin, whose CV includes Cambridge rowing team, MBA from LBS, McKinsey, Trinity Mirror (owner of The Daily Mirror) and 18 years at Google.

He was the Google boss who said in 2016 that he doesn't know his own salary.

Presumably he wants what's best for all of us.

That question is more about identifying propaganda by various actors.

While that's a related issue, it's something different to being centrist... Eg it's possible to create propaganda while being centrist, it just can't be left/right wing political.
