Pope Leo XIV will give his first Sunday blessing and address to a crowd in St Peter's Square in the Vatican today.
He will recite the Regina Caeli prayer, in honour of the Virgin Mary, in his first public address since his election was announced with white smoke on Thursday.
After delivering Sunday mass, Pope Leo will bless those gathered on the square outside - and deliver his reflections.
On Saturday, he visited a shrine outside Rome and then prayed before the tomb of his late predecessor Francis inside the basilica of Santa Maria Maggiore.
