The politicians were at Broadcasting House (they represent London/ SE seats), of the others, one was in Oxford, the other Belfast. I thought the latter was useful as we got a Northern Ireland perspective on a UK issue; the all Northern Ireland panels tend to resort to political point scoring.Of course, radio is different. Whilst browsing this forum, I've been listening to Any Questions. Chris Mason has chaired the programme from his home as he is self-isolated. There were four panel members, not sure where but probably at (different ) studios).
