It only seems like yesterday, but was actually two days ago, that I wondered aloud whether the BBC's capitulation to a complainant's call for the Institute of Economic Affairs (IEA) to be labelled when introduced (e.g. as 'free-market') would lead to think tanks from other parts of the political spectrum receiving similar treatment.
I specifically mentioned BBC favourite the Resolution Foundation.
Well, the BBC is making headline news of another Resolution Foundation report today under the headline Levelling up to cost billions more than government thinks, says think tank and, no, there's not a label in sight in that article. It's simply 'the Resolution Foundation' and 'the think tank'.
Much as could have been guessed.
Other media outlets go with 'left-leaning'.
