What is Behind the Rise of Populism?

Andrew talks to Catherine Fieschi, the founder and executive director of Counterpoint, a London-based consultancy on social and cultural dynamics, and the author of the new book Populocracy: The Tyranny of Authenticity and the Rise of Populism, about why populism and populist parties have become a feature of our politics and how new dynamics unleashed by social media have been harnessed by populism.
