Author and journalist Oliver Bullough traces Britain's vital role in the growth of 'offshore' money laundering, talking to historians, whistle blowers, former investigators, and politicians.

In this episode, Oliver explores how and why Russian oligarchs found London a receptive place to park their wealth after the collapse of the Soviet Union in 1991 - with consequences that are playing out in British politics today.
