The Duke of Edinburgh, recovering from the insertion of a stent at Papworth Hospital, in Cambridge, was visited today by his wife, Queen Elizabeth II, and four children.
The Queen and her three younger children flew by helicopter from Sandringham. The Prince of Wales and the Duchess of Cornwall traveled by car to the hospital.
Queen Elizabeth spent 45 minutes with her husband.
A palace spokesman said: "The Duke is in good spirits. I suspect that he will stay overnight but imagine he will be eager to leave knowing him.
"The Queen has left reassured – knowing he is in good spirits. Christmas plans tomorrow will go ahead with or without Prince Philip.
"I'm not aware of any change. I'm sure the Queen is very concerned of course – but is now reassured.
"We are not commenting further on his condition. There has been no indication at all that there will be any further visits.
"We do not know when he will be released but I imagine he will remain here for a short time."
