In this month's Taxcast: They say history is written by the victors. So how can we rethink the way we use words about tax havens that reflect the reality of what's really happening? We talk to Alain Deneault about his new book in which he writes about laundering with language - Legalising Theft, a short guide to tax havens.  Plus: we discuss the poisoning of a former Russian spy and his daughter on British soil and how by welcoming oligarchs with no questions asked, the City of London has compromised democracy and ushered in an era of oppression, criminality and impunity. And also, how US President Trump's tax reforms have awarded tax write-offs for private jet owners.
