Vatican magistrates have named 46-year-old Paolo Gabriele as the suspect in their investigation, saying he illegally took confidential documents.
A series of leaks, dubbed Vatileaks, has revealed alleged corruption, mismanagement and internal conflicts.
Last month, Pope Benedict XVI set up a special commission of cardinals to find the source of the confidential memos.
Mr Gabriele is the pope's personal butler and assistant and one of very few laymen to have access to the Pope's private apartments."
Surely, the Pope should be rewarding his butler for blowing the whistle!
