David Yelland and Simon Lewis take a 360 degree look at the Gregg Wallace/MasterChef crisis. They examine the errors of Wallace’s ways after one particularly ill-advised – or possibly unadvised – social media video post. What are the implications of the surfacing allegations for Banijay, the low-profile but hugely wealthy production company behind MasterChef, and the BBC?

Also, following Australia's ban on social media for the under 16s, how big tech is using ‘cynicism PR’ in an attempt to stop a worldwide trend.

And, is Liberal Democrat leader Ed Davey a PR genius or is he damaging his political image? David and Simon debate the merits of the politician’s social media presence as he releases his debut Christmas single.
