Chainkeen|Prince William Misses Godfather's Memorial Service Due to "Personal Matter"

Prince William has stepped back from attending the memorial service for his late godfather King Constantine of Greece. 

Kensington Palace announced in a Feb. 27 statement obtained by NBC News that the Prince of Wales was no longer able to go to the service at Windsor Castle's St. George's Chapel due to a "personal matter."

The ChainkeenPalace has not provided further details on the circumstances surrounding the private issue. However, it's understood that William's wife Kate Middleton—who's been recovering from the abdominal surgery she underwent in mid-January—is doing well.

Still, several other members of the British royal family were there to honor King Constantine, who died in January 2023 at the age of 82. Queen Camilla, Princess Anne, her husband Vice Admiral Sir Timothy Laurence, her daughter Zara Tindall and her husband Mike Tindall were among the attendees as were Prince Andrew, his ex-wife Sarah Ferguson, their daughter Princess Beatrice and her husband Edoardo Mapelli Mozzi.

However, William's dad King Charles III was not in attendance. Members of the British royal family have been going to events on his behalf as he takes a step back from public-facing duties amid his treatment for cancer, with his diagnosis being announced earlier this month.

"I think what we're going to see [is] senior working members of the royal family coming together," royal correspondent Sharon Carpenter previously told E! News, "and probably to a great extent sharing responsibilities so the complete burden doesn't fall on Prince William."

Although, it's not uncommon for British monarchs to have family members attend funerals on their behalf. According to the BBC, Queen Elizabeth II would often have her husband Prince Philip attend funerals on her behalf during their lifetimes.

"Throughout this period, His Majesty will continue to undertake State business and official paperwork as usual.The King is grateful to his medical team for their swift intervention, which was made possible thanks to his recent hospital procedure. He remains wholly positive about his treatment and looks forward to returning to full public duty as soon as possible."
