Britain's Prince Philip left a London hospital Monday, 10 days after exploratory stomach surgery.
The Queen’s husband, who turned 92 last week, waved to onlookers and shook hands with medical staff as he left the private clinic where had been treated.
The Duke of Edinburgh, as he is formally known, was admitted on June 6 and is now expected to spend two months convalescing.
Tim Ewart, Royal reporter for Britain's ITV News, said the Prince appeared "extraordinarily fit" for his age.

Prince Philip, Duke of Edinburgh
It was his fourth trip to the hospital in 18 months. He was treated for a recurring bladder infection last August, forcing him to miss the end of the queen’s diamond jubilee celebrations. In December of 2011, he had a stent inserted into his heart.
Last Monday, the Queen wished her husband a happy 92nd birthday in the hospital on Monday, paying Prince Philip a visit where he is recovering from exploratory stomach surgery.
