Conclave 2013: How a new pope is elected
1. The day begins with morning mass in St Peter's Basilica
2. Some 115 cardinals eligible to vote (they must be under 80-years-old) gather in the Sistine Chapel and take an oath of secrecy
3. Lots are drawn to select three cardinals who will collect ballot papers. Three more are chosen to check the results
4. Each voting cardinal writes the name of his favoured candidate on his special ballot paper and folds it in half
5. In order of seniority, cardinals take their ballots to the altar and drop it into a chalice
6. Results are counted and then read aloud
7. A two thirds majority - at least 77 votes - is required to win the election. If there is no result, another vote is scheduled
8. The process can repeat a maximum of four times a day until one candidate gets the two thirds majority
9. At the end of each vote, all ballots are burned in one of two incinerators - one which gives off black smoke in the case of no result, or white smoke if a new pope has been chosen
