By Philip Pullella VATICAN CITY (Reuters) - The Vatican appointed its first auditor-general on Friday in Pope Francis' latest move aimed at ensuring transparency in the scandal-plagued finances at the headquarters of the Roman Catholic Church. A statement said the pope, who has made cleaning up finances a major plank of his papacy, had chosen Libero Milone, a 66-year-old Italian who is a former chairman and CEO of the global auditing firm Deloitte in Italy. Cardinal George Pell, head of the Vatican's Secretariat for the Economy, has said the auditor-general will be autonomous, answerable only to the pope and free to "go anywhere and everywhere" in the Vatican to review the finances and management of any department.
