LONDON (AP) - For decades, he has stood loyally at the side of Queen Elizabeth II and made thousands of solo appearances as well. He calls himself the world's most experienced unveiler of plaques.
He has been eligible for a government pension since June 10, 1986, yet still soldiered on.
Now, at age 95, Prince Philip said he is retiring from royal duties.
The queen's husband said Thursday he will carry out scheduled engagements for the next few months but won't take on new ones starting in the fall.
His retirement announcement followed a night of frenzied speculation caused by news reports about an "emergency" palace meeting Thursday.
Buckingham Palace said Philip, also known as the Duke of Edinburgh, made the decision to retire with the full support of the queen.
Tall, craggy-faced and always elegantly dressed, Philip is as famous for his occasional off-color gaffes and one-liners as he is for his devotion to the monarch, and he joked about his retirement at an Order of Merit reception at St. James's Palace.
"I'm sorry to hear you're standing down," mathematician Michael Atiyah, 88, said, using the British expression for retirement.
"Well, I can't stand up much longer," Philip replied. He walked with his head held high, despite his self-deprecating claim.
Philip has made earlier concessions to age, announcing when he turned 90 in 2011 that he was "winding down" his official duties. He said at the time he felt he had "done my bit."
There were no indications Philip suffers from any new health problems. The statement indicated Philip will carry out previously scheduled engagements between now and August.
Philip, a member of the Greek royal family in exile, sacrificed a successful naval career to support Elizabeth when she became queen.
He became the longest-serving consort in British history in 2009 - much as Elizabeth has become the country's longest reigning monarch.
