We ask whether free travel across Europe is now at risk. Brussels bureau chief of the Financial Times Peter Spiegel gives us his assessment. Also in the programme, tensions escalate between Saudi Arabia and Iran, as the countries sever diplomatic ties. Sanam Vakil, associate fellow of the Middle East programme at Chatham House considers the economic implications. South Africa and the United States are engaged in a game of chicken over poultry imports. We find out more from Alan Mukoki, chief executive of South Africa's Chamber of Commerce and Industry. Plus our regular commentator, Lucy Kellaway of the Financial Times newspaper looks at what she says are exaggerated business virtues: "paranoia" and "disruption".
