King Frederik of Denmark was among the distinguished guests in the Royal Box at Wimbledon on Sunday afternoon.
The 58-year-old monarch and noted tennis enthusiast were joined by longtime friend and confidant Christian von Buchwald as they watched the action at the All England Club.
Nearby sat several notable figures from the world of sports.
Former England cricket captain Sir Andrew Strauss attended with his son Samuel, while former British tennis player and sporting director Deborah Jevans was also in attendance.
Dr. Mark Precious, a former field hockey international and academic, completed the line-up of distinguished guests.
The couple first met when Frederik returned from boarding school in France as a 15-year-old, when he was introduced to von Buchwald.
Their relationship has endured ever since, with von Buchwald later forging a respected medical career.
He now works as a senior physician and professor of ear, nose and throat surgery at Rigshospitalet in Copenhagen.
The closeness of their bond was revealed in 2007 when von Buchwald was chosen as one of six godparents to Princess Isabella.
His wife, Elisabeth, also has a role in the royal household as inspector of the court furnishings.
