The Royal Family is focused on the health of Prince Philip and has "more important things to worry about" than Meghan Markle and Prince Harry's Oprah interview, say palace aides.
Buckingham Palace is bracing for new revelations from the Duke and Duchess of Sussex during the two-hour broadcast on an American TV network this Sunday.
But aides said the Firm's thoughts are firmly with the Duke of Edinburgh, and Harry and Meghan's tell-all with their pal Oprah Winfrey "is not something we are focusing on at the moment".
Philip, 99, spent his first night at St Bartholomew's Hospital in central London last night after being transferred by ambulance from the private King Edward VII's Hospital after almost two weeks there.

It came just hours after he first clips of the Sussexes' interview was released by CBS to promote Sunday's interview.
Philip, Harry's grandfather, is expected to remain at St Bartholomew's Hospital, in the City of London, until at least the end of the week.
One aide told the Telegraph: "The family is very worried about him, and their thoughts are very much with him rather than this Oprah interview.
"They have much more important things to worry about."
Another senior aide said: "This programme is not something we are focusing on at the moment."
A US TV inside described the timing of the interview, given that Philip remains in hospital, as CBS' "worst nightmare".
However the interview is likely to be a ratings winner for CBS and watched by tens of millions of people worldwide.
In the UK, ITV has reportedly splashed out £1 million to secure the rights.
There were calls for CBS to postpone the broadcast, but that is thought to be unlikely to happen.
Philip, who turns 100 in June, continues to be treated for an infection and a pre-existing heart condition.
A royal source told the Mirror the family were "united" in prayers for Philip and the mood shifted when they found out he wouldn't return home soon.
Philip was admitted on Monday to St Bartholomew's Hospital, having been transferred via ambulance to the renowned cardiac centre earlier in the day.
The Queen's husband was said to be "comfortable" after his arrival, having spent the previous 13 nights at the King Edward VII's Hospital in Marylebone.
Buckingham Palace said in a statement on Monday: "The Duke of Edinburgh was today transferred from King Edward VII's Hospital to St Bartholomew's Hospital where doctors will continue to treat him for an infection, as well as undertake testing and observation for a pre-existing heart condition.
"The duke remains comfortable and is responding to treatment but is expected to remain in hospital until at least the end of the week."
Philip was shielded from public view as he left King Edward VII's hospital, where he had received treatment for nearly a fortnight.
Umbrellas were held up as he made his way into a waiting ambulance, at the rear of the hospital, and was taken to St Bartholomew's Hospital in the City of London.
St Bartholomew's is an internationally renowned hospital and Barts Heart Centre is Europe's largest specialised cardiovascular service and a centre of excellence for both cardiac and cancer care.
The duke was initially admitted nearly two weeks ago on February 16 for a few days as a precautionary measure after feeling unwell. A week later, Buckingham Palace announced the Queen's consort was being treated for an infection.
