To mark the 200th edition of the programme, Ernie Rea and guests AC Grayling, Anthony Carroll and Mona Siddiqui discuss whether Britain is now a post-secular society.
What happened to the perceived wisdom that modernity would see religion wither and die? Why has the post-millennium world seen a rise in interest in all matters religious rather than the expected decline? Does immigration and 9/11 account for this resurgence in religion or are other factors at work? And should faith have a public space in today's complex world; should it have more rights than trade unions and political parties?
