Do we really have ‘superflu’?

The NHS is warning of an unprecedented flu season - we check what the numbers say. Is there really a mass exodus of Brits leaving the UK due to Labour tax policies? We look at the latest emigration figures. We take a look at the prison service’s curious habit of letting prisoners out early – or keeping them in for too long - is there a trend? Plus - why the US economy can’t grow at 25 percent a year. Presenter: Tim Harford Reporter: Nathan Gower Producers: Charlotte McDonald, Katie Solleveld, Lizzy McNeill and Tom Colls.
