It's just really odd,
when recording it last night thought it would be an issue?
I can only guess they thought they could clear anything up in the edit. They finished the edit, the BBC saw it and realised it couldn’t go out. Would explain why it was so late in the day, but surely someone producing the programme would have thought before hand? Seemingly not.
The episode with Johnny Mercer a couple of weeks ago would presumably have had the compliance lawyers hooping up and down, but still went out - it's interesting that they're happy to face down a potential libel case, but not a due impartiality slap on the wrist from Ofcom.
Interesting perspective from someone with a lot of relevant experience:
