Sam's guest in this week’s Spectator Books is Peter Pomerantsev. Peter lived in Moscow for a decade as a TV producer, and chronicled the metastasis in that country of 'post-truth politics' in his bestselling Nothing Is True and Everything Is Possible. His fascinating and dismaying new book, This Is Not Propaganda: Adventures in the War Against Reality, describes how Russia’s surreal new information politics turned out not to be a weird exception, but the harbinger of a worldwide phenomenon. In this new book, part travelogue, part reportage, part memoir, he travels from the Philippines to Ukraine, from Mexico to Beijing, to investigate how the internet — which we once thought would be the great political disinfectant — has been weaponised by criminal regimes worldwide.

Spectator Books is a series of literary interviews and discussions on the latest releases in the world of publishing, from poetry through to physics. Presented by Sam Leith, The Spectator's Literary Editor. Hear past episodes of Spectator Books here.
