Queen Elizabeth II's husband, Prince Philip, will stop carrying out public engagements this fall, Buckingham Palace announced Thursday. The palace said in a statement that Philip, who's 95, has the full support of the queen in his decision. He will continue heading numerous charitable organizations but will not play an active role attending engagements, the AP reports. In the past, Philip, the Duke of Edinburgh, has suffered heart problems but has maintained a vigorous public schedule. The palace did not offer any new details about his health. Earlier Thursday, there was frenzied speculation among palace-watchers as royal staff from across the UK were summoned to a meeting. (Prince Philip was all smiles hours before the announcement was made.)
