The Prince of Wales has visited his wife in hospital where she is recuperating from abdominal surgery.
Prince William was seen leaving the private London Clinic at around 12.35pm today.
Meanwhile, Queen Camilla has said the King is "fine" and "looking forward to getting back to work" during an official engagement in Aberdeen this afternoon.
Kensington Palace announced yesterday that the Princess of Wales had abdominal surgery and will remain in hospital for up to two weeks.
Sky News understands the planned surgery is routine and the princess's condition is non-cancerous.
The 42-year-old was admitted on Tuesday to The London Clinic, a private hospital in central London.
Dr David Lloyd, a London-based GP, told Sky News that up to two weeks was "quite a long time in hospital for a planned operation".
He said the length of time indicated this "isn't something small" and that such stays could even include procedures as serious as the removal of an organ.
The most common abdominal surgeries, he said, were for appendix and gallbladder problems, along with hysterectomies.
The palace has not said exactly what kind of surgery the princess has undergone.
Dr Lloyd added that this kind of private hospital was like a "five-star hotel and you can choose the surgeon and choose the time of your doing it".
This afternoon, William drove himself away from the hospital in an Audi e-Tron GT Carbon Vorsprung, followed by a Land Rover Discovery, and left by the back entrance following the visit.
Kensington Palace said: "The prince has just left hospital after visiting his wife."
The princess is not expected to return to royal duties until after Easter. Prince William is also set to postpone engagements while his wife is in hospital.
Buckingham Palace also announced yesterday that the King is set to undergo treatment for an enlarged prostate next week.
