Financial Times investigator Cynthia O’Murchu and Oxford University business historian Chris McKenna join Richard to tell the story of Greensill Capital - a financial scandal that turned political and battered the reputation of a former British prime minister.

Anti-money laundering specialist and former police officer Martin Woods talks to Richard about the front line of the war on dirty cash. Martin became the first whistleblower to expose the role of British banks and shell companies in laundering money out of the former Soviet region. He reveals how it happened and the personal price he paid for his trouble.

Are sanctions worth it? In our second episode, Richard welcomes leading economic crime specialist Tom Keatinge to Filthy Lucre. They explore whether state-imposed penalties offer a hope of stemming the flow of dirty money from Russia and elsewhere or whether they are, all too often, an empty gesture.

The opening episode of Filthy Lucre asks the question "how corrupt is the UK?". Focusing on Britain’s role in the corruption that has kept Vladmir Putin in the Kremlin for more than two decades, with best-selling author Oliver Bullough (Moneyland and Butler to the World) and Spotlight on Corruption director Sue Hawley.
