Pope Francis, the former Cardinal Jorge Bergoglio of Argetnina, delivered his first blessing to a huge crowd in St Peter's Square on Wednesday night, asking for the prayers of "all men and women of good will" to help him lead the Catholic Church.

Francis, speaking Italian with a slight Latin American accent, joked with the crowd before delivering his blessing, saying: "As you know the duty of the conclave is to give Rome a bishop. It seems that my brother cardinals went almost to the end of the world."
