Catholic cardinals are gathering at the Vatican to elect the successor to Pope Francis, who died on April 21. Voting will take place in the Sistine Chapel, with ballots continuing in succession until any candidate secures two-thirds of the available votes.

Cardinals will take part in a Mass at St Peter's Basilica this morning and will later walk to the Sistine Chapel to cast their votes under Michelangelo's frescoes. Once they enter the chapel, they will have no communication with the outside world until a new pope is elected.
