Charles had a trip planned to Scotland during the unveiling, Insider reported, citing The Sun.

A source told The Times of London, “He does find it terribly difficult. These moments have the potential to resurface old wounds, and it brings back memories for him; happy, sad, regretful.”

However, their sons, William and Harry, did attend the unveiling of the statue, designed by Ian Rank-Broadley, at Kensington Palace’s Sunken Gardens. Harry traveled to the UK from his home in Santa Barbara, California, to attend the event.

“Today, on what would have been our mother’s 60th birthday, we remember her love, strength, and character – qualities that made her a force for good around the world, changing countless lives for the better,” they said in a joint statement. “Every day, we wish she were still with us, and our hope is that this statue will be seen forever as a symbol of her life and her legacy.”
