LONDON —Britain's Prince Philip, the 90-year-old husband of Queen Elizabeth, had heart surgery to ease a blocked artery on Friday after being rushed to hospital with chest pains as he prepared to celebrate Christmas with the royal family.
Britain's longest-serving royal consort, known for his outspoken and sometimes brusque manner, needed an operation to fit a small tube known as a stent that keeps the blood vessel open.
Philip had been preparing to spend Christmas with other members of the royal family, reportedly including Prince William and his wife, Catherine, at the Sandringham royal estate in eastern England.
He was taken to the Papworth Hospital in Cambridge, one of Britain's main heart and chest centers, about 60 miles away, a palace spokeswoman said.
"The Duke of Edinburgh was found to have a blocked coronary artery, which caused his chest pains," the palace said in a statement. "This was treated successfully by the minimally invasive procedure of coronary stenting."
He will stay in hospital "for a short period" under observation, it added. The hospital declined to comment.
Philip had attended a lunch for staff a week ago and had been on "very good form," the BBC reported.
"He has had these chest pains before and I don't think it's anything untoward, but given his age they are being safe rather than sorry," former royal press spokesman Dickie Arbiter told the BBC.
Despite his age, Philip generally has been in good health and has continued a busy round of charity work and social engagements, recently visiting Australia and Ireland.
A pivotal figure in the House of Windsor, Philip has a reputation as a fiercely loyal consort who prefers outdoor pursuits to introspection.
"The Queen is monarch, but within the family setting, the Duke of Edinburgh is hugely important," royal commentator and author Penny Junor told Sky News.
"He has always been the one who has called the shots in family matters. He has really made the major decisions."
Born on the Greek island of Corfu in 1921, Philip served in Britain's Royal Navy before marrying Elizabeth in 1947. They have four children, including the heir to the throne, Charles.
The prince has no clear-cut constitutional role. In private he is regarded as the unquestioned head of his family, but protocol obliges the man dubbed "the second handshake" to spend his public life one step behind his wife.
In a rare public tribute to her husband, the queen said in a speech in 1997:
"He is someone who doesn't take easily to compliments but he has, quite simply, been my strength and stay all these years, and I...owe him a debt greater than he would ever claim, or we shall ever know."
