In 1981, the world was completely gripped by royal wedding fever as Prince Charles prepared to marry Lady Diana Spencer.
They spent months planning their special day, which would be watched by millions of people around the world.
And once the dress was fitted, the cake was designed and the guestlist finalised, the engaged couple sat down with two journalists for a final interview to chat about the celebration.
Angela Rippon, the anchor on BBC news, and ITV’s Andrew Gardener were the two lucky journalists invited to quiz the couple.
Their questions had to be pre-approved and they were warned not to stray from the script.
Charles and Diana came across as a couple very much in love and looking forward to their wedding – which was set to be the event of the decade.
But looking back with hindsight, there was one moment of the interview which revealed the heartbreaking reality.
Speaking in Channel 5 documentary Charles and Di: The Truth Behind their Wedding, Angela discussed the interview in depth for the first time.
She said: “When we first arrived at the Palace and met Prince Charles and Diana in a corridor, Prince Charles as always was very relaxed. Lady Diana less so, it was a whole new experience for her.”
Before they went in they were given a briefing by the Queen’s press secretary Michael Shea.
He told them very firmly that the interview would be ended if they asked any questions that had not been agreed.
During the interview Michael stood directly behind Angela out of camera shot, but in Diana’s eyeline.
“I’m not quite sure how comfortable it made her feel.
“I got the impression that Princes Charles was very protective towards her.
“Lady Diana was almost slumped in the chair, she was in new territory. She was out of her depth.
“Put any 20-year-old in front of a television camera and say this is an interview about what could be one of the most important days of your life and it’s going to be seen by hundreds of millions of people around the world, and there is this man standing behind the person interviewing you making sure you get it right.
“Crikey, anyone would be nervous.”
Angela watched the interview back in full for the first time for the new documentary.
She said: “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.”
But the final few moments of the interview really stand out to her, when she wishes the couple a lifetime of happiness.
Charles looks Diana, but she looks down at the floor.
“That expression on Diana’s face at the end speaks volumes.
“Maybe we should have read so much more into that five seconds at the end the interview. It might have told us so much more about what was to come.”
After the interview they were invited up to the private quarters for a cup of tea, and away from the strict press team Angela asked about the dress.
She didn’t ask for details, but just asked the bride if it was everything she had dreamed of.
Angela said: “She clasped her hands together and she said, ‘Angela, I had my last fitting just a few days ago in the work room and when I put the dress all the girls in the workroom applauded and some of them cried and said ma’am, you look just like a fairy princess.’
“And I think at that moment I could have willingly strangled Michael Shea.”
