A charming octogenarian who plays ruthless games with the people who think they're going to succeed him: I reckon Logan Roy would have recognised a kindred spirit in Pope Francis, despite their diametrically opposed politics. Like many of you, I'm heartbroken that Succession has come to an end – but if you're missing the back-stabbing melodrama then you could always start following the real-life struggle to shape the Catholic Church after Francis. Plenty of cardinals would like to swap their red cassocks for a white one. But, as I suggest in this episode of Holy Smoke, whoever eventually takes the job will have to confront at least five nightmare situations, most of them created by the camera-friendly but privately ferocious current occupant of the See of Peter.
