On the eve of the Queen's visit to the Vatican, Panorama examines Pope Francis's shake-up of the Catholic Church. He was elected only a year ago, but this Argentinian Pope has garnered a great deal of public attention, and nearly all for positive reasons. Whether it be his strong line over historic sex scandals in the church, or even his embrace of a person with 'elephant man's' condition - he seems to be the Pope that members of the Catholic church have been waiting to come along. In this doc, Jane Corbin travels to his homeland of Argentina to find out what drives him and whether he is raising expectations by promising reforms that some in the Vatican will not allow him to carry out.
