Russia's Most Wanted | Investigation

When Bill caught wind of widespread financial corruption in the country, he decided to act - making powerful enemies in the process. Vanessa Kirby unravels a story of money, power and terrible sacrifice. Would YOU challenge the powers that be? From SPYSCAPE, the home of secrets. A Cup And Nuzzle production. Series producer: Gemma Newby. Produced by Mariana Des Forges. Music by Nick Ryan.

Correction: The original programme stated that Japan, Australia and New Zealand have all passed Magnitsky acts. It has been corrected to reflect that these countries are only debating passing Magnitsky-style acts.
