Rebrands, name changes, financial black holes. Just what is going on with WH Smith?

This week, David Yelland and Simon Lewis look at the reputation of a high street institution. With stores up and down the country now being called TG Jones, what sort of messaging - if any - has taken place between the new owners and Smith's existing customers? And with most of us looking for a cheap online deal, they'll also explain why retail PR is no longer the glamorous industry it once was.

And in the extended edition on BBC Sounds, who wants to live forever? Well the answer seems to be the leaders of China and Russia. President Xi Jinping and President Putin have been overheard discussing how the advances in biotechnology could lead to eternal life. This happened just before a social media frenzy suggesting President Trump had died. He hadn't. But in a world of increasingly elderly leaders, what are the PR challenges of persuading the rest of us that they're alive and well and fit for office?

Plus it's Coldplay versus KitKats. Yes, the summer has been bookended by two big sex scandals. One of them revealed very publicly at a Coldplay gig - the other, behind the closed doors of Nestle. But as Simon and David explain, the level of coverage a scandal receives doesn't always dictate how serious it is.
