The total cost of Volkswagen's diesel emissions scandal is now set to reach $30bn. We hear about that, and the news that a senior VW executive has been arrested in Germany. Also in the programme, we have a report from Catalonia ahead of an independence referendum this weekend which the Spanish government has declared illegal. We hear from Microsoft CEO Satya Nadella, in conversation with Kai Ryssdal from US public radio show Marketplace, about his two years so far running one of the world's biggest tech firms. Entrepreneur Elon Musk believes he can develop a rocket that could connect any two cities on Earth in under 60 minutes. Professor Alan Duffy from Swinburne University of Technology in Melbourne tells us how likely that is. Plus we look back at the rest of the week's big business news with Justin Fox from Bloomberg View in New York, and Rebecca Byrne of the Wall Street Journal in London.
