LONDON >> Britain’s Queen Elizabeth II attended church near her country estate while her husband of 72 years, Prince Philip, remained in a London hospital today.

Palace officials have not provided an update on the 98-year-old prince’s condition following the announcement Friday that he was being admitted to King Edward VII Hospital as a precaution due to a preexisting condition.

“The admission is a precautionary measure, on the advice of His Royal Highness’ Doctor,” the palace said in a statement.

Philip had been at the royal family’s Sandringham estate in eastern England, where the queen and her family usually spend Christmas. The palace said Philip didn’t travel by ambulance and his admission wasn’t an emergency. It is not clear if Philip will be released in time to join the rest of the royal family on Christmas Day.

The private King Edward VII hospital in central London has been treating members of the royal family for decades.

Philip, also known as the Duke of Edinburgh, married Elizabeth in 1947 and is the longest-serving royal consort in British history. He and the queen have four children, eight grandchildren and eight great-grandchildren.

A former naval officer and keen polo player, Philip enjoyed robust health well into old age but has had a number of health issues in recent years. He stopped attending public engagements in 2017.

The queen has not altered her holiday routine and went to church today as normal. The royal family is expected to attend another service on Christmas morning.

Buckingham Palace released a special holiday photo showing the queen making Christmas desserts with her son, Prince Charles, her grandson Prince William and her great-grandson Prince George.

The three princes are, respectively, the first, second and third in line for the British throne.
