Dame Penny Mordaunt says King Charles was bored out of his mind at Coronation dress rehearsals until Prince Louis arrived and got the session stopped for a Crown Jewels tour.
The former defence secretary and Lord President of the Privy Council told an audience at the Cheltenham Literature Festival that the monarch had endured two weeks of practice and simply had enough. She watched him glaze over while seated in the Coronation Chair at Westminster Abbey on the Thursday before the May 6, 2023, ceremony.
Then five-year-old Prince Louis appeared. Charles sprang back to life. Officials halted the rehearsal so the king could show his grandson the Crown Jewels, a pause Mordaunt called a memory she will treasure. The Daily Mail reported her firsthand account of the behind-the-scenes moment.
Louis, now 8, later appeared with the family on the Buckingham Palace balcony after the Coronation. The visit during rehearsals offered a simple reminder that even the weight of a centuries-old ceremony can yield to a grandchild’s arrival.
Mordaunt described the scene without polish. Charles was not merely tired. He was bored out of his mind after the long run of dress rehearsals leading into the big day.
She put it plainly to the festival crowd.
"We were doing dress rehearsals on the Thursday before, and the King was bored out of his mind. He'd just done two weeks of this, and he'd had enough. I was watching him glaze over in the Coronation Chair."
The turn came fast.
"And then he suddenly sprung to life because beside him was Prince Louis, who had come to visit. They stopped the rehearsal so that he could show Prince Louis all the Crown Jewels. That's a memory that I shall treasure."
Family moments like that still cut through the formality that surrounds the monarchy, including the public strains and reported rifts that have followed the royal household in recent years.
Mordaunt carried the ceremonial Sword of State, a 17th-century piece, 1.2 meters long and weighing 3.6 kilograms, as part of her Privy Council role. She became the first woman in British history to present the Jewelled Sword of Offering to a monarch.
She did not romanticize the wait. Before the ceremony, participants lined up in the cloisters at Westminster Abbey, timed to join the end of the London procession so the Royal Family could enter on schedule. Mordaunt faced hours on her feet with the heavy sword and refused to stand that long in heels.
"I said, 'Well, I'm not putting my heels on.' So I was there in this fabulous demi-couture dress, with these great big fluffy slippers on, with all the Pursuivants of Arms, who had got their robes stuffed with Fruit Pastilles, and I had this nightmare that I was going to forget to put my shoes on."
She wore a teal Safiyaa dress and matching hat rather than the black-and-gold court outfit her male predecessors had used. Nude heels went on only when it was time to walk. Practical choices beat empty pageantry when the job requires holding a historic blade for hours.
That same sense of duty has marked other chapters of Charles’s reign, from refusing expansive historical apologies on travel to convening serious discussions on technology and control of new tools, as when he brought tech leaders together in Scotland on artificial intelligence.
After the Coronation, even Labour voices lined up to compliment the performance. MP Chris Bryant called Mordaunt “mightier than the sword.” MP Emily Thornberry posted on X: "Got to say it, Penny Mordaunt looks d*** fine! The sword bearer steals the show."
Mordaunt had already handled a solemn constitutional task in 2022. As Lord President, she opened the Accession Council proceedings, formally announced the death of Queen Elizabeth II, and took part in the proclamation of King Charles III.
Charles, now 77, and Queen Camilla completed the Coronation on May 6, 2023. The rehearsal story Mordaunt shared years later adds texture to the public record without rewriting it. It shows a grandfather who lit up when a young prince appeared, and an official who carried a heavy sword in slippers until the moment required heels.
Legal and political pressures have circled the palace before, including attempts to drag the king into court fights over history, yet the courts have shut down activist efforts to turn grievance theater into criminal process.
Charles has also drawn hard lines on the road, declining the open-ended apology-and-reparations demands that activists pushed during Caribbean stops, a stance consistent with institutional continuity over fashionable guilt rituals.
The fuller picture of royal family history remains contested ground, with memoirs and claims still flying, including those leveled in Charles Spencer’s account of the Diana years.
A bored king, a paused rehearsal, and a five-year-old at the Crown Jewels still say more about durable family order than most of the noise that surrounds it.
