Catholic cardinals on Monday set May 7 as the start date for the conclave to elect Pope Francis' successor, delaying the secret voting for two days so they can get to know one another better and find consensus on a candidate before they are sequestered in the Sistine Chapel.

Roman Catholic cardinals will begin their secret conclave to elect the new leader of the global Church on May 7, the Vatican said, confirming what a source had previously told Reuters.

Cardinals have no contact with the outside world after the master of liturgical ceremonies utters the words “Extra Omnes” the Latin phrase for “all out,” to ask all those present except the cardinal electors to leave the Sistine Chapel to begin the voting process.
