Philip recovering after heart op
The Duke of Edinburgh is expected to remain in hospital for Christmas Day, where he is recuperating following treatment for a blocked coronary artery.
Philip, 90, was spending a second night at Papworth Hospital near Huntingdon, Cambridgeshire, having undergone the coronary stent procedure.
Buckingham Palace said Philip had a "good night" following Friday's surgery and was "eager to leave".
He is expected to remain under observation for a short period but no further details have been given about when he will be discharged.
It is thought to be the first time the Duke will miss the Christmas morning service at Sandringham, the Queen's private Norfolk estate, which has become an annual tradition for the Royal Family since the early 1990s.
A large media presence is expected at Sandringham when the Queen and her family make the short journey to St Mary Magdalene Church on the royal estate, where they are spending Christmas.
Buckingham Palace has said the service will go ahead as planned and no changes to the family's celebrations are expected.
One of the highlights of the day is undoubtedly when the royals gather around a television to watch the monarch's traditional Christmas broadcast.
This year, the monarch talks about the importance of family in the message which was recorded on December 9, two weeks before her husband was taken ill. The Queen leaves the room and lets her family watches the national address without her.
The festive weekend will also see the Duchess of Cambridge spending her first Christmas as a member of the Royal Family.
