America's best known companies - Facebook, Amazon, Google and Apple - have faced attacks on all sorts of fronts - whether it's over the use of personal data, stifling competition, allowing copyright infringement or paying too little tax. Now they're in Washington defending what they do in front of committees of politicians. We hear from Karen Kornbluh, director at the German Marshall Fund of the United States and former US ambassador to the OECD. We also speak with mayors who are defying national immigration policies around the world. Beppe Sala, mayor of Milan explains why he is dismayed by the direction Italy's national government is taking on migration. Eric Garcetti, who is mayor of Los Angeles tells us why he is taking a stand against Donald Trump's national policies on the issue. Marvin Rees, mayor of Bristol, explains changes he'd like to see made to the UK's asylum system. And Yvonne Aki Sawyer, mayor of Freetown, Sierra Leone, discusses the impact that an exodus of thousands of skilled and unskilled workers is having on her city. # Also in the programme, we meet actor and YouTuber Oliver Thorn, who is giving away the contents of his philosophy degree for free online.
