The EU Commission president Ursula von der Leyen warned of a possible global food crisis. One of the world's biggest fertiliser companies is Yara International of Norway, and we ask its chief executive Svein Tore Holsether for his take on the global food security situation. Also in the programme, the online marketplace for renting private homes, AirBnB, is pulling out of China, as a result of the country's tough and ongoing Covid restrictions. We find out more from the BBC's Nick Marsh in Singapore. Commuters around London have a completely new rail line spanning the British capital available for use from today. The project was several years behind schedule and around $5bn over budget, and the BBC's George Thomas has been for a ride. Plus, the BBC's Jo Critcher meets some of the female entrepreneurs in Africa, who are using financial technology to give more people access to money and services through apps, payment platforms and chat bots. Today's edition is presented by Mike Johnson, and produced by Nisha Patel and Sara Parry.
