David Yelland and Simon Lewis look at why private schools seem to be losing the PR battle over their VAT exemption. A core principle of PR is to anticipate problems and mitigate them. This one has been coming down the track towards independent schools for years - why did they get it so wrong? Also, the Liberal Democrats' election strategy of "tactical disruption" - which mainly involves Sir Ed Davey getting wet and apparently having the most fun of all the leaders on the campaign trail. As David and Simon continue to look at the use of PR by different political parties during the election campaign, they ask if the Liberal Democrats are adopting the PR tactics pioneered by disrupters like Richard Branson’s Virgin Atlantic and Airbnb in the US. It's winning the party precious press coverage, but is there a downside to the election stunts? And what does it mean for the concept of a Fan Hitting crisis if being a convicted felon is not necessarily career ending? David and Simon are, of course, talking Donald Trump's guilty verdict in his hush-money trial. Does reputation matter in a post-shame world?
