VATICAN CITY – Cardinals said Monday they want to talk to Vatican managers about allegations of corruption and cronyism within the top levels of the Catholic Church before they elect the next pope, evidence that a scandal over leaked papal documents is casting a shadow over the conclave and setting up one of the most unpredictable papal elections in recent times.

The Vatican said 107 of the 115 voting-age cardinals attended the first day of pre-conclave meetings, at which cardinals organize the election, discuss the problems of the church and get to know one another before voting.

The red-capped "princes" of the church took an oath of secrecy and decided to pen a letter of "greeting and gratitude" to Benedict XVI, whose resignation has thrown the church into turmoil amid a torrent of scandals inside and out of the Vatican.
