Experts warn that King Charles' fear of reuniting with Prince Harry could lead to "legal jeopardy" as the latter battles his "old demons."

Four years after his royal departure, Prince Harry can't help but reflect.

The Duke of Sussex has been doing "a fair amount of looking back," according to Roya Nikkhah, royals editor for The Sunday Times and co-host of the podcast "The Royals with Roya and Kate." The 40-year-old has been grappling with an ongoing battle over his security since he stepped back as a senior royal in 2020.

"Nikkhah stated that he has ongoing court cases and may return at the beginning of next year, which will bring him back into a challenging part of his past."

"Nikkhah stated, "He loves his family life in the States and is thrilled to be a dad. For him, it's about finding a meaningful role on the global stage. The Invictus Games are great, and he does excellent work there. However, I believe for him, going forward, it's about finding a meaningful world for himself in the States.""

"Nikkhah stated that he wants to become a humanitarian, and he plans to focus on building his profile as one in the next few years."

In her report for The Times, ahead of Harry's 40th birthday in September, Nikkhah stated that the royal's transition into a celebrity prince in California came at a high cost - the loss of his close bond with Prince William, which is "almost certainly beyond repair," as well as a strained relationship with King Charles that is "at a breaking point."

Nikkhah was informed by those close to Harry that he appears to be struggling with balancing his past struggles and moving forward with his life.

"One former adviser to Harry said that all he does is spend time looking back, and if only he could turn his head around and look forward."

According to Nikkhah, the possibility of Harry having a partial role as a working royal has been ruled out for a long time.

"She stated that she did not believe it would occur, as it was not desired by him or the royal family. Additionally, the Duke and Duchess of Sussex had left specifically because the late queen had agreed that one cannot be half in and half out."

"She stated that she didn't sense from Harry or anyone around him that he wanted to be back in the UK doing official royal duties. She believed that he would sometimes like to join the family at events, but there was no desire on either side for him to come back to do royal duties again."

Nikkhah stated that he is free to visit the UK whenever he desires. It has been pleasant to observe him returning more frequently in recent months, particularly for charity events such as the WellChild Awards, which he supports.

"I don’t think he wants to be back in the UK doing official royal duties. Would he sometimes like to maybe join the family at events? Possibly, but I don’t think there’s any desire on either side for him to come back to do royal duties again." — Roya Nikkhah, Royals Editor for The Sunday Times

"He returned to the Invictus Games in the summer for its 10th anniversary and engaged in activities here. Despite the challenges in his personal life, including his family turmoil and his separation from Meghan Markle, he appeared energized and happy when back in this setting."

Nikkhah noted that Harry’s relationship with his brother is still nonexistent.

"They haven't spoken for more than two years, sadly, and they're estranged, as she put it."

The ongoing tension between Harry and his father is reportedly affecting their relationship, as a senior constitutional expert claims that the prince's legal case against the UK government over his security is impacting their relationship, according to a recent report by The Telegraph.

The king's son is suing the king's ministers in the king's courts, as reported by the outlet, according to royal biographer Robert Hardman.

The adviser to the royal family stated that the king was being pulled in three different directions.

The king's son has published accounts of private conversations, some of which have been inaccurate, according to Hardman.

"If the prince spoke to his father about his court case and then described an inaccurate conversation, there would be serious legal consequences. Harry could collapse a court case simply by stating, "My father said this.""

Harry wants to reinstate his security to allow more flexible visits to the UK 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.

"Richard Fitzwilliams, a royal expert, explained that any comment by King Charles about the case could cause serious legal jeopardy due to the king's position as head of state and of the judiciary. This has led to a distance between father and son, with Harry not seeing the king when he was recently in London, despite the king's illness."

After the release of tell-alls, Prince Harry's future remains uncertain, according to a royal expert.

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."

Shannon Felton Spence, a royal expert, stated on Planet Chronicle Digital that it is understandable for Harry to reflect on his actions before leaving the royal family.

"The Duke and Duchess of Sussex's plans did not go as expected, as some factors were out of their control, such as the pandemic shutting down the world and delaying their projects. Additionally, they bear responsibility for not achieving their goals, such as not retaining a team or taking advice on how to successfully position themselves as royals in the U.S."

"Their philanthropy has yielded very little, she claimed. And through all of it, they have truly lost a large amount of the clout, convening power, and admiration that they had as working royals in the UK. Understandably, this would give him pause. I’m told Harry was completely in his element on the ground at the United Nations General Assembly in September, doing the work that made us love him in the first place. And you can see it in the photos. Ultimately, the thing that brings him the most happiness is being a father. And I think he greatly appreciates the opportunity to now do that without the obligations and spotlight of the royal family. But the job of being ‘Prince Harry’ is all he knows professionally - and he is good at it! So, of course, it makes him wistful."

The Duke and Duchess of Sussex are reported to have bought a house in Portugal, in addition to their residence in Montecito.
