With the seat of the Catholic Church on its doorstep and the highest number of priests of any country, Italy is a bastion of global Catholicism. And yet, unlike many other countries, it has failed to confront the scourge of clerical sex abuse. It keeps no official statistics on the issue and the number of convictions remains shockingly low. Survivors of abuse have fallen foul of a combination of cover-ups, complicity and legal failings in their search for justice. After a report in France last year found that there had been some 3,200 paedophile priests there since the 1950s, pressure is growing on Italy for a similar reckoning. For Assignment, Mark Lowen has set out to ask how and why abuse has been hidden in Italy, speaking to survivors, confronting those accused and meeting officials working to uncover the dark secrets that the Italian authorities have been unwilling to investigate.
