By the end of the 2000s Murdoch’s empire in the UK seemed impregnable. But, as Murdoch knew so well, the problem if you are an establishment is there will always be someone trying to bring you down. And at the heart of Murdoch’s operation was a secret very few knew about. It involved celebrity sex lives, journalistic surveillance and Prince William’s kneecap. It would take a crusading journalist and a provincial lawyer to expose it, almost bringing Murdoch’s business to its knees and leaving him facing his “most humble day”.

David talks to the people right at the heart of this story: Nick Davies – the journalist who exposed the phone hacking scandal, Mark Lewis – the lawyer whose case against the News Of The World lit the fuse that would eventually lead to Murdoch closing the paper down, and Dan Evans – the phone hacker extraordinaire who ended up turning against his old colleagues.
