The Queen holds two titles that date right back to Henry VIII: 'Defender of the Faith’ and ‘Supreme Governor of the Church of England'. The coronation is always held within the context of a religious service and there is no doubt that the Queen has a deep Christian faith but how relevant is her role as Defender of the Faith in a Britain where membership of the Church of England is in decline and minority ethnic religious groups are growing?

To discuss these issues, Ernie Rea is joined by Martin Palmer who was Prince Philip’s Religious Advisor on the environment; Rabbi Julia Neuberger - a Crossbench Peer in the House of Lords; Dr Jasjit Singh - an Associate Professor in the School of Philosophy, Religion and the History of Science at the University of Leeds; and Dr Daniel Loss from Harvard University - an historian of modern Britain.
