Cardinal Robert Francis Prevost – now known as Pope Leo XIV — is the first pope from the United States. The 69-year-old from Chicago is known as a leader with global experience. He spent much of his career as a missionary in South America and most recently led a powerful Vatican office for bishop appointments.

Tens of thousands cheered as Leo, successor to the late pope Francis, appeared on the balcony of St Peter's Basilica to deliver his first address.
