The Vatican has launched a rare criminal investigation to uncover who is behind leaks of highly sensitive documents that allege corruption and financial mismanagement in Vatican City. The documents also shed light on purported infighting over the Vatican Bank's compliance with international money-laundering regulations. A television show in late January on an independent network first revealed letters addressed last year to Pope Benedict XVI from the then-deputy governor of Vatican City, Archbishop Carlo Maria Vigano. Vigano complained of corruption within the church and protested orders to remove him from his post and send him to be the papal nuncio, or ambassador, to Washington. Under Vigano's watch, the Holy See balance sheet went from $10 million in the red to almost $45 million in the black in just 12 months. By being kicked upstairs, Vigano wrote, his efforts to clean up the Vatican would be stopped and would also tarnish the pontiff's image by bringing into question his resolve to establish transparency inside the Vatican. Italian authorities are investigating the origin of $33 million in Vatican funds deposited in Italian banks. The Italian media have reported that JP Morgan Chase is closing the Vatican Bank's account with its Milan branch because it felt the Holy See had failed to provide sufficient data on money transfers.
