The 37-year-old is scheduled to attend events in Manchester and London before jetting to Germany with wife Meghan, Duchess of Sussex, by his side.
“Harry has not been at the top of the Queen’s Christmas card list for a couple of years now, but at the end of the day, he is still her grandson and she loves him,” says a palace insider.
“If her health is declining in a way that suggests the family should gather, there is no question about it – she would want Harry to be there.”
Harry’s relationship with his grandmother has remained fraught since he and Meghan, 41, departed the UK under a cloud of controversy in 2020.
When the couple delivered a string of alarming allegations during a chat with Oprah Winfrey in 2021, the sovereign was forced to release an infamous statement that said while Meghan and Harry certainly remain much-loved members of her family, “some recollections may vary”.
She is also understood to have not given her blessing to the Sussexes when they named their daughter Lilibet in honour of the Queen’s childhood nickname.
“No-one will deny there are problems between grandmother and grandson, but if she were to summon him to be by her side, Harry would drop everything,” says the source.
Charles’ daily visits
Multiple UK outlets report that Prince Charles is visiting with his dear mum on a daily basis, with one insider saying the frequency of his presence at Balmoral is “highly unusual”.
“Charles and his parents were never particularly close when he was a kid, in fact there was quite a lot of friction there,” says a palace source.
“But as he got older, he became closer with the Queen and Duke of Edinburgh. Few will forget how emotional he was when visiting with the Duke in his twilight months, and it’s fair to say it’s even more sad for him to be with his mum while she’s in pain.”

“Princess Beatrice and Princess Eugenie have also taken their babies, Sienna and August, for a visit this summer.
"The Queen’s family has had its ups and downs, but she’s so proud of the dynasty she’s created.”
