Given recent issues, I found last night's episode of 'The Bottom Line':
https://en.wikipedia.org/wiki/The_Bottom_Line_%28radio_programme%29
a BBC Radio 4 discussion & BBC World Service programme, most interesting.
Although its topic was the role of boards of directors of commercial companies, much of what it had to say about the selection and training of appropriate board members, and issues such as diversity, skill-matching, and group psychology, was more generally applicable.
The episode, titled 'Managing the Boardroom', is available on BBC iPlayer:

and as a podcast:

One of the panellists, Margaret Heffernan:
