Margaret Thatcher's funeral in St Paul's Cathedral was attended by thousands of world leaders and watched by millions more around the world. In death, as in life, Margaret Thatcher shaped the occasion: she dictated the order of service and chose the hymns and readings. She was probably the most overtly Christian Prime Minister of the twentieth century up to the time of her leaving office. So where did those Christian influences come from? How did her religious conviction shape her politics? And what is her legacy in terms of the relationship between religion and politics in a multi cultural Britain?
