A look back at one of the most memorable moments in TV history, when Diana, Princess of Wales, was interviewed by Panorama reporter Martin Bashir. Diana candidly opened up about her marriage to Prince Charles and her life as a member of the royal family, in a programme that drew an audience of 22.8million people in the UK. With testimony from both BBC insiders and some of those closest to Diana, the programme uncovers why the Princess chose to take this extraordinary gamble and reveal how Bashir - then a comparatively unknown BBC outsider - came to gain her trust.
