Prince Philip misses pre-Easter church service with Queen Elizabeth due to hip issue

Philip, 96, retired from his royal duties last summer.

The duke of Edinburgh's absence from the event appears to have been last-minute; his name had been printed in a program listing the attendees at the centuries-old event.

Philip retired from royal duties last summer.

His condition is not thought to be serious: He was spotted driving on the Windsor Castle grounds on Wednesday, according to the U.K.’s Press Association.

It is unclear whether Philip will attend the royal family's Easter service at Windsor Castle on Sunday.

Philip is currently expected to attend Harry and Markle's May 19 wedding at St. George's Chapel with other members of the royal family.

Queen Elizabeth attended today's Maundy Service as planned.

In a tradition that dates back to the 1660s, the queen distributes Maundy money each year to senior citizens in recognition of their work. The money, presented in a white pouch, is distributed by the monarch during the service.
