Almost exactly ten years ago, on 13 March 2013, Cardinal Jorge Bergoglio became Pope Francis. In the subsequent decade, this previously obscure Argentinian cleric has revolutionised the papacy while steering the Catholic Church through sweeping reform, inside and out. He’s scandalised conservatives and thrilled some progressives, while overturning what the watching world assumed popes had to be like.

In today’s episode we speak with two biographers of Francis to find out their assessment of the pope’s ten years in office. What has he achieved? Where have his ambitions fallen short? Why do some Catholics love him, and still more loathe him like few popes before. And what legacy will he leave behind when he does eventually leave behind the throne of St Peter?
