Pope Francis's death at the age of 88 means the Catholic Church must choose a new leader. Here's how cardinals elect the next pontiff at the conclave.

The decision was made at the Fifth General Congregation, held on Monday morning in the Vatican's Synod Hall. The conclave will take place in the Vatican's Sistine Chapel, which will remain closed to visitors during those days.

VATICAN CITY (AP) — 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.
