Electric carmaker Tesla has said it will cut its workforce by 7% after the "most challenging" year in its history. But in an email to staff, founder Elon Musk said that growth had been strong. We hear from Caroline O'Donovan, Tesla reporter for the Buzzfeed. Also in the programme, Europe's Ryanair airline has just issued a profit warning. Sally Gethin of the Gethin's Inflight News blog tells us why the company faces difficulties. We have a report from Michigan on the health of the US economy. We take a look at the companies getting on board with Veganuary, where people try veganism for a month, to boost sales.
