London's new pollution charge begins

Drivers of older, more polluting vehicles face a new charge to drive into central London. We hear from one person who was advised to move away from the city because of the health risk from pollution, and get business reaction to the new charge from Lily Gray, director at First Mile, a recycling company that makes 150 zero emission deliveries a day. And the BBC's Louise Dewat in Dakar, Senegal, explains how air pollution affects residents there. Also in the programme, with elections in India scheduled for next month, will a new film about Indian prime minister Narendra Modi swing voters to his favour? Naman Ramachandran covers south Asian cinema for Variety, and gives us his view. Plus our regular workplace commentator Stephanie Hare considers how the digital world means your boss is able to keep tabs on you, even when you're on the treadmill.
