Expert: Prince Harry's 'demands' led to King Charles excluding him from Christmas.

According to reports, Prince Harry and Meghan Markle were not invited to spend Christmas with the royals. A expert explains the reason behind this.

According to Ingrid Seward, editor-in-chief of Majesty magazine and author of "My Mother and I," extending an invitation to the Sussexes was "too much" for King Charles.

"Seward stated, "I am not surprised they weren't invited because I believe the general sentiment is that it would have created an unnecessary tension, and Christmas is about joy and harmony. Additionally, I think King Charles couldn't handle the drama.""

"Seward stated that his exhaustion was due to both his cancer and his workaholic nature, which made it difficult for him to rest. Additionally, the thought of having Harry and Meghan as his in-laws was overwhelming, causing him to feel even more drained."

People magazine reported that the Duke and Duchess of Sussex were not invited to this year's Sandringham gathering, and they haven't been present for Christmas with the royal family since their wedding in 2018.

Harry and Meghan are reportedly planning to spend the holidays in the U.S. with their two children, Prince Archie and Princess Lilibet, who reside in California.

Seward, 76, stated that the monarch not wanting to see his grandchildren does not mean he doesn't care about them.

"She claimed that she believed he was desperate to see his grandchildren. However, Harry wouldn't come unless he had this, that, and the other. He also demanded an armed escort and made too many demands. She understood completely. Meanwhile, Charles stated, "I'm not going to ask them this yet.""

Harry wants to reinstate his security to allow more flexible visits to the U.K. for himself, his wife, and their two children, according to insiders who spoke to People magazine.

The monarch has stopped responding to his son's phone calls and letters, according to sources, which claim that the issue is crucial to their ongoing estrangement.

For over four years, Harry has been battling in court for his protection in the U.K.

In 2020, the Duke of Sussex forfeited his taxpayer-funded personal protective security after relinquishing his role as a working member of the royal family.

"I think [the king] is desperate to see his grandchildren. But Harry won’t come here unless he has this, that and the other. And he wants an armed escort, and he’s making too many demands." — Ingrid Seward, editor-in-chief of Majesty magazine and author of "My Mother and I"

During his visit to the U.K. in May for the Invictus Games' 10th anniversary, Harry declined an invitation from the king to stay at a royal residence.

The Duke of Sussex allegedly rejected the offer because it lacked security measures, which would have required remaining in a public area with entry and exit points and no police presence, according to The Telegraph.

Harry remained at a hotel, as he had done in previous trips.

At the time, neither the father nor the son's representatives responded to Planet Chronicle Digital's requests for comment.

On May 8, Harry celebrated the Invictus Games anniversary with a thanksgiving service at St. Paul's Cathedral while Charles and other senior royals attended a garden party at Buckingham Palace.

A spokesperson for Harry, 40, revealed to Planet Chronicle Digital that the king was occupied and unable to meet with his son.

The Italian prince is also going through a difficult time after leaving the royal family, but it's important to respect his privacy regarding his personal matters.

The king and his younger son will make amends in the future, according to Seward's hope.

"I believe that the children will eventually unite them, hopefully," she stated. "Charles deeply desires to see his son as any father would... and to see his grandchildren. Although he has only met them briefly, they are growing up. However, I don't think it will happen because the royal's life is so busy. The king's schedule is incredibly packed, with appointments every 20 minutes of the day. As a result, Harry must adapt to fit in with him."

"Seward explained that when Harry arrived, his father was unable to see him due to being too busy, which may sound terrible to us. However, if one has 20-minute appointments, it is not feasible to fit someone who hasn't been seen in a while into a 10-minute slot. It is probably better to be too busy."

"Seward acknowledged that it is challenging, but he believes it won't persist indefinitely. He hopes it won't last forever. Although Charles' cancer scare and Catherine's cancer scare may have brought the family together, if that doesn't happen, Seward is uncertain about what will."

Charles' annual birthday celebration, Trooping the Colour in June, did not include an invitation for Harry and Meghan, who are 43 years old.

According to People magazine, Prince William, his wife Kate Middleton, and their three children will spend Christmas at Sandringham. Neither Buckingham Palace nor Kensington Palace, which manage the offices for the Prince and Princess of Wales, have disclosed the Christmas guest list.

William, 42, and Harry's relationship remains tense.

Despite meeting in February following Buckingham Palace's announcement of his cancer diagnosis, communication between father and son has worsened, according to People magazine.

"A friend of Harry's informed the outlet that he is "unavailable right now" and his calls go unanswered. Despite trying to reach out about the king's health, those calls also remain unanswered."

Since quitting royal duties, Harry has had a strained relationship with his family due to the unbearable intrusions and racist attitudes of the British press.

Since his rocky relationship with his family became public, the father of two has shared his story in TV interviews, a documentary, and his memoir, "Spare."

According to a pal who spoke to People magazine, the couple felt they had no other option but to leave the royal family.

"According to the source, the only viable solution was to depart - for their mental well-being. It is believed that they thought leaving the bubble would reduce the attention on them."

The security of the royal family should not be affected by the couple stepping away from their royal duties.

"According to the source, the king's son, Harry, would be happiest if he could rekindle his bond with his father, regardless of his royal status."

You can't reverse bloodlines at the end of the day, the insider stated.
