Prince Harry and Meghan Markle have been urged to return from their Canada trip with the Duke of Edinburgh in hospital for a fourth night.
Prince Philip, 89, is being cared for at London's King Edward VII's Hospital and some Royals want the Duke and Duchess of Sussex to return for what might be a "last family Christmas".
The couple are due to miss the Queen's traditional family gathering on December 25 at Sandringham because of their six-week holiday overseas.
Philip's admission into hospital on Friday follows a spell of ill health - with sources calling it a 'planned visit'.
There is some suggestion he suffered a fall while elsewhere there are reports of him battling flu-like symptoms.
A royal source said the family is keen to see the Sussexes, adding there is a feeling they are being "inconsiderate and selfish" given the Queen and Philip's "advancing age",
“Even before the Duke became ill, many were at a loss as to why Harry and Meghan would miss what could be one of the last family Christmases with the Queen and Philip," a source told the Sun .
"They are absolutely entitled to a proper break and privacy, but they've had six weeks off.
“Many of the family were very keen to see him over Christmas, but were told they couldn’t as they were abroad."
The source added that it might be nice for some family photos with baby Archie including all the Royals.
But instead Harry and Meghan released a solo crawling towards the camera while his parents sit in the background laughing.
A palace aide said: “The decision to base themselves in Canada reflects the importance of this Commonwealth country to them both."
Philip is said to be being looked after "very well" for treatment relating to a "pre-existing condition".
His admittance to the private hospital, which has been treating members of the royal family for decades, was described as a "precautionary measure" by Buckingham Palace.
Photographers and TV crews were stationed outside the building on Monday evening as police stood guard and royal protection officers waited in cars.
Asked about Philip's health, his eldest son the Prince of Wales told reporters on Monday: "He's being looked after very well in hospital.
"At the moment that's all we know."
During the visit to flood-hit communities in South Yorkshire, Charles added: "When you get to that age things don't work so well."
The duke, who turned 98 in June, has generally enjoyed good health, appearing to recover well from a planned hip replacement operation in April 2018.
