Roberto Saviano made a rare appearance in the UK in July 2015 when he came to the Intelligence Squared stage. In conversation with Intelligence Squared's very own Robert Collins, Saviano talked about his life in hiding and his beginnings as a reporter on the streets of Naples. He revealed his latest work of investigative reporting, 'Zero Zero Zero', in which he delves into the sprawling network of the global cocaine trade. He traced how the $400 billion a year generated by drugs trafficking filters into the international banking system through money laundering from Wall Street to the City of London. The cocaine trade isn’t just a playground for criminals, Saviano argued. It is part of the structure of our global economy where some of the biggest players — the banks — have profited without facing a single criminal conviction.
