Why did it take an ITV drama for a huge miscarriage of justice to get the headlines it deserves? As the government races to respond to public outrage over the Post Office scandal, The Media Show meets some of the key journalists who have reported on it over the last 15 years, and asks why it is only now that the story is cutting through. Guests: Rebecca Thomson, former Computer Weekly journalist; Nick Wallis, presenter of The Great Post Office Trial; Tim Brentnall, former sub-postmaster; Ian Hislop, Editor of Private Eye; Amelia Gentleman, reporter at The Guardian Presenter: Katie Razzall Producer: Simon Richardson
