Guest: Nigel Biggar, Regius Professor Emeritus of Moral and Pastoral Theology at the University of Oxford and the Author of ‘Colonialism: A moral Reckoning’. The Sunday Times bestseller has been described as, ‘a new assessment of the West’s colonial record that offers a moral inquest into the colonial past, forensically contesting damaging falsehoods and thereby helping to rejuvenate faith in the West’s future’.
