Following the death of Pope Francis, Edward Stourton looks at the life and legacy of the spiritual leader of more than a billion Catholics worldwide. He was elected at a time of crisis for his Church, but quickly transformed its reputation. He urged Christians to be less judgemental and more welcoming of gay and divorced people. And as the first Pope from the Global South, he put the poor at the heart of the Church’s mission, speaking up for migrants and refugees and those worst hit by the impact of climate change. Edward Stourton speaks to people inside and outside the Catholic Church - including those who worked closely with him.
