King Charles and Queen Camilla supported his nephew as guests at his royal remarriage.

The royal couple was among the attendees as Peter Phillips wed Harriet Sperling on June 6 at All Saints Church in Kemble, a village in the Cotswold district of Gloucestershire, England.

There was speculation that King Charles, 77, and Queen Camilla, 78, wouldn’t make the wedding after The Jockey Club announced on May 29 that the royal couple would attend Betfred Derby Day at Epsom Downs on the same day, taking place about 100 miles away. They are joint patrons of The Jockey Club, which owns and runs Epsom Downs Racecourse, and it’s a longstanding tradition for royals to attend the event.

However, the King and Queen were indeed in attendance, alongside other members of the royal family like Prince William and Kate Middleton, Prince Edward and Sophie, as well as Peter’s mother, Princess Anne and her husband, Vice Admiral Sir Timothy Laurence, and Peter’s sister, Zara Tindall, and her husband, Mike Tindall.

Peter and Harriet revealed their wedding date in April, with a statement from their spokesperson saying, “Both families have been informed jointly of the wedding date by invitation. Their Majesties The King and Queen, The Prince and Princess of Wales have also been informed of the announcement.”

King Charles and Queen Camilla have a special connection to the bride and groom.

It is the second marriage for both Peter, Princess Anne’s son, who works as an entrepreneur, and Harriet, a nurse. Similarly, Charles and Camilla wed in 2005 after previously being married to other partners — Charles to Princess Diana and Camilla to Andrew Parker-Bowles — and having children.

Peter was married to Autumn Kelly from 2008 to 2021, and they share two teenage daughters: Savannah, 15, and Isla, 14. According to Hello! magazine, Harriet was previously married to fitness instructor Antonio St. John Sperling, with whom she shares 13-year-old daughter Georgina. Harriet, Peter and all three daughters joined King Charles and the royal family for Easter church at Windsor Castle earlier this year.

While there were plenty of royal guests at Peter and Harriet’s nuptials, his cousin Prince Harry wasn’t invited to his cousin’s nuptials, according to Hello! magazine. A friend of the couple told the outlet, “Peter and Harry haven’t spoken for several years and have simply lost touch, so he hasn’t been invited.” (Spokespeople for Prince Harry and Peter had no comment when reached by PEOPLE.)

In addition, Hello! reported that the former Prince Andrew and Sarah Ferguson were not among the invited guests, with a friend saying their presence at the event would be a “distraction” amid renewed interest in their ties to Jeffrey Epstein.
