Prince William will not attend the memorial service for Greece's late King Constantine due to personal reasons, a royal source told CNN.
The 41-year-old Prince of Wales was due to attend a memorial event at Windsor Castle on Tuesday.
The source did not elaborate on the last-minute change in plans, but added that Prince William's wife, the Princess of Wales, is recovering from abdominal surgery in January and “remains in good spirits.”
The source added that Prince William called his family to inform them that he would not be able to attend.
Duchess Kate has been away from the public eye as she continues to recuperate at home, and is not expected to return to royal duties until after Easter.
Charles III is also absent from royal duties as he continues to receive treatment for an undisclosed form of cancer. The 75-year-old monarch recently revealed that he was brought to tears by the many messages of support he has received since being diagnosed with cancer.
Another royal source told CNN there was no connection between the Prince of Wales's personal issues and the king's health.

Constantine II of Greece, a second cousin of Charles III, died in January last year at the age of 82.
Charles and Constantine developed such a close relationship that the British royal family named his cousin godfather to their eldest son William.
After a military coup in 1967, Constantine and his family fled to Rome, and the military government appointed a regent in his place.
The Greek monarchy was abolished on June 1, 1973, and the military junta declared the country a republic. This decision was confirmed by a subsequent referendum. After another referendum was held by the civilian government elected in 1974, Constantine accepted abolition.
