Even before his name was announced from the balcony of St Peter's Basilica, the crowds below were chanting "Viva il Papa" - Long live the Pope.

Robert Prevost, 69, will be the 267th occupant of the throne of St Peter and he will be known as Leo XIV.

He will be the first American to fill the role of Pope, although he is considered as much a cardinal from Latin America because of the many years he spent as a missionary in Peru, before becoming an archbishop there.

Born in Chicago in 1955, Prevost served as an altar boy and was ordained as a priest in 1982. Although he moved to Peru three years later, he returned regularly to the US to serve as a pastor and a prior in his home city.

He has Peruvian nationality and is fondly remembered as a figure who worked with marginalised communities and helped build bridges in the local Church.
