Princess Kate risks 'scolding' from King Charles after latest Royal Family appearance

King Charles and Camilla paid a separate visit to the same event on the day, however, their appearance received less coverage than expected.

A royal insider has shared his disappointment at the lack of reporting on the King's engagement.

An insider told the Daily Mail: "With his love of horticulture, His Majesty's appearance at Chelsea was an important engagement.

"It's a shame that his visit with Her Majesty the Queen received less coverage than might have been expected.

"I hope they are not too disappointed."

Royal sources have expressed concern that the King and Queen's visit was overshadowed by a surprise appearance from the Princess of Wales.

Earlier this year, Prince Harry claimed Charles and Camilla did not like William and Kate drawing attention away from their causes and that measures were in place to avoid this.

The Duke of Sussex wrote in his autobiography Spare: "Pa and Camilla didn't like Willy and Kate drawing attention away from them or their causes.

"They'd openly scolded Willy about it many times."

Harry referred to one occasion when his sister-in-law was scheduled to undertake an engagement at a tennis club on the same day that Charles and Camilla were due to appear elsewhere at an official event.

The Duke claimed that this had been strictly prohibited as it would ruin Charles and Camilla's chances of being on the front page of the papers the following day.

Harry wrote: "That couldn't be tolerated. Told that it was too late to cancel the visit, Pa's press officer warned: 'Just make sure the Duchess doesn't hold a tennis racquet in any of the photos'."
