Celeb chef Jamie Oliver in call for ban on junk food ads before 9pm watershed - is he talking sense on childhood obesity? @EJWoolf and Fionola Meredith debate

Jamie Oliver has told a select committee that more taxation is not the way to curb the UK's obesity epidemic. He and fellow celebrity chef Hugh Fearnley-Whittingstall were giving evidence to the Health and Social Care Select Committee. He said it's time for Theresa May to "do what's right". Both chefs are calling for measures to encourage healthy eating - including a ban on junk food adverts before the 9pm watershed. But is this a fight that Jamie Oliver should be tackling? Vinny got the views of commentators Emma Woolf and Fionola Meredith.
