The College of Cardinals is holding its first official meetings at the Vatican on Monday. The top agenda item is choosing which day to start the closed-door conclave that will elect the new pope. With no clear front-runner, the conclave outcome is unpredictable.
The papal resignation has put the cardinals in an unprecedented situation in modern history.
"The real mood is of shock and disappointment — this resignation desacralized the figure of the pope," says Massimo Franco, author of several books about the Vatican. He says a pope cannot be treated like a company CEO.
