India's financial shock therapy continues, this time with an all-new tax system. The BBC's Rahul Tandon reports on its progress. Presenter Ed Butler speaks about the new plan with businessman Gaurav Daga, founder of plastics supply company Oswal Cable, near New Delhi. And Simon Ruda, the director of home affairs and international programmes at the Behavioural Insights Team in London, also known as the Nudge Unit, says getting people to pay tax isn't as simple as it might seem.
