High street fashion giant Inditex has appointed the founder's daughter as its new chair. The firm owns brands including Zara and Massimo Dutti, and we find out what's behind the appointment of Marta Ortega from Dan Dombey of the Financial Times in Madrid. Also in the programme, authoritarian regimes are thought to be working closer than ever to keep each other afloat, with plenty of help from the West's financial system. We hear from Frank Vogl, who helped found the global anti-corruption organisation Transparency International. And we get wider context from the historian, journalist and author, Anne Applebaum. Plus, scientists have struggled for a long time to learn as much as they'd like about the world of infrasonic sound. These acoustic waves can travel a really long way but as they're below the range of human hearing you need to be able to place sensors where you can pick up various sources of infrasound. Now a team of research collaborators from the US, the UK, South Africa and the Netherlands has cracked it - use a seabird to do your recording for you. We hear from Olivier den Ouden at the Royal Netherlands Meteorological Institute to explain.
