Journalist and award-winning filmmaker Andy Webb obtained the secret files that first broke the story of Princess Diana's betrayal by journalist Martin Bashir. He talks to Gavin Esler about the true extent of the deception the Princess experienced before giving her iconic 1995 Panorama TV interview, and how key players at the BBC then devised an elaborate cover-up to hide what happened, whilst leaving Diana to her fate.

Andy Webb worked as a reporter for BBC Television for more than 15 years, including on the BBC’s Watchdog, before embarking on a career as an award-winning director of documentary films.

Gavin Esler is an award-winning television and radio broadcaster, novelist and journalist, best-known as one of the three main presenters on BBC2’s Newsnight.
