Author and journalist Oliver Bullough traces Britain's vital role in the growth of 'offshore' money laundering, talking to historians, whistleblowers, former law enforcement investigators and politicians. In this episode, he traces the origins of offshoring back to the sleepy City of London of the 1950s. A moment of inspiration fuses with the shock of the Suez Crisis to create the launch of a whole new approach to finance - with consequences that are still playing out right now.
