Queen Elizabeth's 86-year-old husband Prince Philip has been taken to hospital with a chest infection, Buckingham Palace said on Friday.
Here are some key facts about him:
* Philippos Schleswig-Holstein Soenderburg-Glucksburg was born on a dining room table on the Greek island of Corfu on June 10, 1921, the fifth child and only son of Prince Andrew of Greece.
* Philip's parents went into exile when he was 18 months old. They sailed from Corfu with him sleeping in a cot made hurriedly from orange boxes.
* He was educated at Gordonstoun, a tough school in Scotland, where his son, Prince Charles was later an unwilling pupil, and became a naturalised British citizen, looking and sounding every bit the English gentleman.
* Philip joined Britain's Royal Naval College at Dartmouth, southern England, as a cadet, in 1939. He graduated top of his class and served on battleships, cruisers and destroyers during World War Two. He was mentioned in dispatches, took part in the Allied landings in Sicily and was in Tokyo Bay when the Japanese surrendered in 1945.
* Princess Elizabeth and Prince Philip first met when at the wedding of Prince Philip's cousin, Princess Marina of Greece, to The Duke of Kent, who was an uncle of Princess Elizabeth, in 1934.
* They were married at Westminster Abbey on November 20, 1947 in a spectacular ceremony attended by statesmen and royalty from around the world.
* He continued his naval career until 1951, then took indefinite leave and devoted himself fulltime to public duties when Elizabeth became queen a year later.
* Philip's reputation, and that of the queen, has suffered as the marital problems of their children have mounted.
* He is known for his acerbic wit but has also caused offence with off-the-cuff remarks: He once told British students in China: "If you stay here much longer, you'll be slitty-eyed
