The next vote will take place at about 17:30 (16:30 BST) - no smoke will signal no decision has been reached, white smoke that there is a new pope

Cardinals began the papal conclave at the Vatican's Sistine Chapel to select a new pope after the death of Pope Francis. What does black smoke mean?

A new pope will be selected when a candidate gets a two-thirds-plus-one majority vote by the cardinal electors. White smoke will be sent up the chimney of the Sistine Chapel when that happens, to indicate a new pope has been chosen.
