She added: 'And obviously, with the knowledge of hindsight, you read so much more into body language, what was said, looks that were given, reactions, that's the value of hindsight isn't it?’
Angela says that Charles was considerably more relaxed in the interview than Diana, who Angela says could have been intimidated by the presence of Michael Shay, the Queen's then Press Secretary.
'When we went into the room, Michael was standing behind me, out of camera shot but behind me and in Lady Diana's eye-line,' she added.
Meanwhile, Elizabeth Emanuel, the fashion designer who made Diana's iconic wedding dress said that she and husband David had to “start again a couple of times”, and that Diana had gone from a 29-inch waist down to just 23.
Diana’s former employer Mary Robertson also gave her first ever TV interview in the doco and revealed that despite the rumours, the princess was very much in love with Charles.
“She was very much in love with Prince Charles or certainly with the image of Prince Charles.”
The Prince of Wales married Lady Diana Spencer in the royal wedding of the century at St Paul's Cathedral in London in July, 1981.
But after their divorce in 1992 and Diana's death five years later, Charles moved on with Camilla Parker-Bowles.
