It was only a few months ago that Prince Harry was being roundly criticised pretty much everywhere. An ill-judged and hot-headed BBC interview where he discussed the King's health did him few favours. And yet, this week, there has been a shift.

In this week's episode, David Yelland and Simon Lewis discuss whether this is a genuine turning point for Harry's PR.

Also, in the extended edition on BBC Sounds, they'll explain why it might not all be over for the master of spin, Peter Mandelson. He may have been sacked and his reputation might be in ruins - but don't assume that means there aren't still plenty of people who'd like a quiet word with the 'Prince of Darkness' of PR.

And speaking of reputations being in the sewer, David and Simon will be talking about an actual one. The Tideway tunnel to be precise. What's surprising is that it's a £5bn infrastructure project that has come in pretty much on time and on budget - and yet, you probably haven't heard of it. Just why is it so much harder to get PR for good news compared to bad?
