Three Vatican figures, including two senior members of the clergy, have been named as suspected moles in a scandal that has seen the Holy See rocked by a series of damaging leaks.
The new suspects are reported to be Cardinal Paolo Sardi, a former Papal speechwriter; Bishop Josef Clemens, the Pope's former personal assistant; and the Pope's German housekeeper Ingrid Stampa.
Mr Gabriele has been blamed by Vatican investigators for passing on sensitive documents that have led to the widespread publication of reports claiming nepotism, death threats, gay smear campaigns and tax irregularities at the Holy See. One of the leaked documents suggested Pope Benedict's new ambassador in Washington was exiled in the US because he had blown the whistle on financial corruption.
