We talk to Oliver Bullough about his acclaimed new book Moneyland: Why Thieves and Crooks Now Rule the World and How to Take it Back.  Where is Moneyland?  How did London become its capital?  And will Brexit, or a Corbyn government, or another financial crash change how it operates?  A conversation about tax havens, money-laundering, the politics of corruption and the corruption of politics.  With Jason Sharman, author of The Despot's Guide to Wealth Management, and Helen Thompson.
