Overview: Panzuto was a mafia boss, and a hardened killer. For years he played a key role in Naples' Camorra, but now he has turned state witness and is helping put his former associates behind bars. Dominic Casciani gains exclusive access to an Italian anti-mafia prison to meet Panzuto and hear his story of love, murder and betrayal. It's a tale which took him from the back streets of Naples to a caravan park in Blackpool. We hear from those at the sharp end of the ongoing battle against organised crime in Naples, and from those who believe the tide has finally turned. Above all we hear from the man himself: why did he decide to break with the Camorra, and what does the future hold for him?
