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

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.

In a tradition that scholars date to the 19th century, smoke released from a chimney will be colored white if the cardinals have made a decision, or black if they remain deadlocked.
