The British Royal Family will celebrate this year’s Christmas for the first time with King Charles III as the host. But, a source recently claimed that Meghan Markle and Prince Harry are not likely to join them this December.

Express UK noted in a report that the celebration would also mark the family’s first without Queen Elizabeth II. This comes months after her passing, which saw the Duke and Duchess of Sussex with the British Royals as they mourned the loss of the Queen.

Reportedly, the King is understood to have invited the former working royals to celebrate Christmas at Sandringham.

The outlet stated, though, that Meghan Markle and Prince Harry are not seemingly making a trip back to the U.K. for the holiday season, citing a report from MailOnline, which first published the claims on Sunday.

As noted, a source, allegedly close to King Charles III, told the publication that Prince Harry and Meghan Markle “are unlikely to attend.”

No other details have been shared, though, regarding the matter.

The former working royals, alongside their camp, have also yet to make any confirmation about the report.

MailOnline said elsewhere in its piece that Kate Middleton and Prince William will be there, adding that they would stay at Anmer Hall, nearby the Sandringham estate.

Moreover, it stated that other members of the British Royal Family are expected to join King Charles III and Queen Consort Camilla on Christmas as they make their way to church in the morning.

The British Royals, alongside Buckingham Palace, have yet to make official announcements about their plans for this year’s Christmas. But, reports have stated that the family is likely to mark the holiday at Sandringham as they have done over the years with Queen Elizabeth II.

Meghan Markle and Prince Harry last celebrated Christmas with the British Royal Family in 2018.

Meanwhile, Prince Harry’s highly anticipated memoir, “Spare,” will hit the shelves two weeks after the festive season. The announcement of its official release and title emerged in late October, more than a year after the public first learned about the material.

Vanity Fair, in its report covering the matter, quoted the memoir’s publication CEO Markus Dohle from a press release, stating, “Penguin Random House is honored to be publishing Prince Harry’s candid and emotionally powerful story for readers everywhere.”

It continues, “He shares a remarkably moving personal journey from trauma to healing, one that speaks to the power of love and will inspire and encourage millions of people around the world.”

The outlet also said the book will discuss the moment the Duke of Sussex and the new Prince of Wales walked behind their late mother’s coffin in 1997.
