The leader of the world’s 1.2 billion Catholics will be formally enthroned at a mass in St Peter’s Square, with city authorities preparing for an influx of up to one million people to Rome. Jorge Mario Bergoglio, 76, who until his election was Cardinal Archbishop of Buenos Aires, is the first pope from Latin America and the first Jesuit to become pontiff.
