“She is his rock, and I can’t actually emphasise that enough. She is somebody who is completely loyal, and she isn’t somebody who has huge highs and lows,” she said.
She went on to explain that the King includes her in every aspect of his life—not just in formal settings, but across the board—underscoring just how important her steady presence is to him.

Charles III: The Coronation Year offers a rare glimpse behind the scenes of the King’s coronation, including rehearsal moments and the touching scene where the Prince and Princess of Wales arrive at Westminster Abbey with their children, greeting the King just like any other family would.
In a heartwarming moment not often seen in public, King Charles warmly embraces each of his grandchildren—starting with Princess Charlotte, then Prince George, and finally little Prince Louis, who eagerly reaches out for a hug.
The documentary also features Fiona, the Marchioness of Lansdowne, sharing her thoughts on the royal couple. Speaking to the BBC, she said: “Whether they’ve sort of had to fight to get there, or whether it’s…” She went on to add that their bond is clearly strong and built on mutual support, especially evident during the coronation.
