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

The United States is home to 10 of the 133 cardinals eligible to vote for the next pope. That's more than any other nation except Italy, home to 17 of the electors who will gather at the Vatican’s Sistine Chapel on Wednesday for the conclave that will choose a successor to Pope Francis.

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.
