Since the election of an overwhelmingly secular Labour government, people who describe themselves as humanists have a spring in their step: for example, there's a prospect that humanist weddings will be legally recognised in England and Wales (they already are in Scotland).

But what exactly is a humanist? Definitions vary and there's a heated debate about to what extent the ethical but firmly atheist beliefs of the rather loosely organised modern humanist movement are descended from Christianity. In this episode of Holy Smoke we'll hear from Andrew Copson, CEO of Humanists UK since 2010 & President of Humanists International, and the theologian and Spectator contributor Theo Hobson, author of God created Humanism: the Christian Basis of Secular Values. Damian Thompson spoke to them earlier and, as you'll hear, it was a lively encounter.
