Atheist Marcus Brigstocke clashes with the Rev Richard Coles in a discussion about the irrationality of religious belief in an unusually combative edition of Heresy. Victoria Coren is aided in her attempts to maintain order by comedian Natalie Haynes, who argues that agnosticism is the only rational position to be adopted on the issue. Victoria's guests find more consensus in taking a heretical position against the received wisdom that Kate Middleton should get a job, and that transport strikes are terrible for commuters. Producer: Brian King An Avalon production for BBC Radio 4.
