Royal fans were delighted by Kate Middleton's appearance at Trooping the Colour on June 14, 2025, particularly as her aquamarine Catherine Walker coat dress channeled Princess Diana in the best way. Now, a royal expert has suggested King Charles's respect for his daughter-in-law was also on display at Trooping the Colour.

The Duke, 40, and Duchess of Sussex, 43, last attended the military parade in 2022 for Queen Elizabeth’s Platinum Jubilee. Two years prior, they had stepped away from their royal duties and relocated to Montecito, California. Therefore, the couple had to watch the ceremony from a separate balcony alongside other non-working royals.

King Charles and Queen Camilla appeared at the annual Trooping the Colour celebration as the monarch continues to undergo treatment for cancer.
