Pope Francis was hailed as a reformist when he became Pope in 2013. He vowed to get a handle on the scandals plaguing the Catholic Church, including how the Vatican managed its money. In 2015, he appointed the Vatican's first ever auditor, former Deloitte CEO and chairman Libero Milone. Along with his business partner, they went through the various Vatican departments checking the books, but came up against resistance from the 'old guard'. In one Vatican office in particular, Milone claims he met strong opposition when trying to audit their accounts. Eventually he claims being forced to resign because he was starting to uncover major financial irregularities. A few years after he was forced out, a high ranking Cardinal, Angelo Becciu, was found guilty in a Vatican court of embezzlement and fraud, for losing the Vatican over €100 million in a London property investment. Now Milone is taking a €9.3m lawsuit against the Vatican for unfair dismissal, loss of income, and emotional distress. Colm Flynn went to meet Libero Milone in Rome. LIbero says he took on the job as a way of giving back to his Church, and, driven by his faith.
