Alastair Campbell says the media is awash with a culture of negativity - is he right? We examine the former spin doctor's Hugh Cudlipp lecture with press correspondent Stephen Brook and media consultant Steve Hewlett. Also on this week's podcast, we're at a Bafta debate on the future of reality TV, with panelists Natalka Znak, the driving force behind I'm A Celebrity, former BBC director general Greg Dyke and ex Sun editor Kelvin MacKenzie. We also talk to Philip Glenister and Keeley Hawes, stars of the Life on Mars follow-up, Ashes to Ashes.
