One of the biggest mafia trials in Italian history is expected to deliver its verdict in the coming weeks. Prosecutors have asked for sentences totalling more than 4,000 years in jail for hundreds of alleged ‘Ndrangheta collaborators. One prosecutor of the ‘Ndrangheta, Nicola Gratteri, cannot travel without a heavy police escort, nor see his children for more than a few hours every couple of months. On the Sky News Daily, host Niall Paterson is joined by our Europe correspondent Siobhan Robbins, who has visited the court where hundreds of ‘Ndrangheta collaborators will be tried, to hear more about what it takes to put this powerful mafia behind bars.
