A widely-reported BBC bias story this week concerned a BBC freelancer on Twitter - namely Inside Science presenter Adam Rutherford.
Adam didn't think that Mr Stringer (a former analytical chemist) should be appointed to the House of Commons Science and Technology Committee because of his 'sceptical' views on global warming, and urged his followers on Twitter to protest against the Labour MP's appointment.
That's a striking affirmation of the BBC's policy - a policy many a BBC tweeter regularly ignores on all manner of issues.
Listening to this week's Inside Science, Adam (in passing) mentioned his telling-off:
Some controversy followed with questions about the scientific credentials, the gender imbalance and some of the opinions of some of the members of the committee. As you may be aware this has been the source of some indignation from some of us in the science community. I got myself in some hot water earlier this week by tweeting about it. Setting that aside...
Inside Science then broadcast an interview Adam recorded "last week" (i.e. before the storm about his tweet) with the resolutely non-sceptical-about-global-warming, anti-Brexit Lib Dem MP Norman Lamb, focusing on how outrageous both of them felt it is that there aren't enough woman on the committee, and on Brexit-related matters.
I've noted before how Inside Science does sometimes seem to take on a campaigning role on various issues. Though Adam Rutherford went too far even for the BBC on Twitter (by directly attacking a Labour MP), his programme often 'goes too far' for me on air in the way of pushing agendas, despite often being very interesting. I doubt even this will make that change.
