Prince William is said to have banned his brother Prince Harry from ever returning to the royal fold.

The explosive claim came from British royals expert Hilary Fordwich, who said the heir to the British throne is taking a no-nonsense approach to addressing his ongoing sibling feud.

"It is widely known within the family that Prince William has laid down an absolute ban on Harry returning in any way, shape or form into his former royal family fold," Fordwich claimed to Fox News Digital.

"If anyone will relent, it would be King Charles III, whom, of course, Prince William won’t challenge, who still misses his ‘darling boy’ and would like to see more of Prince Harry," Fordwich claimed. "However, to this day, after the release of ‘Spare’ and the Netflix serial, as well as with everything else Harry has said, done, and not done, it’s Prince William who adamantly refuses to even speak to his brother."

A spokesperson for Kensington Palace, which handles the Prince of Wales’s office, didn’t immediately respond to Fox News Digital’s request for comment.

Fordwich’s statement came days after King Charles’ former royal butler Grant Harrold told the New York Post that there’s one thing the Duke of Sussex could do to be welcomed back into the family.

"The only way I see this happening is a public statement from Harry, where you come out and say that you were in a bad space and that [his memoir ‘Spare’] was a mistake," said Harrold.

"I don’t think that’s going to happen," he noted. "Some bad things were said, and some families never patch things up, and that’s how it is… Harry has got a big heart, and a part of him probably wishes things would be different."

While the king, 75, may be willing to spark peace talks with his younger son, Fordwich claimed that William won’t be so easily convinced.

"Prince William is the most unlikely royal to ever forgive Harry for all his despicable indiscretions," Fordwich claimed. "He is now very much seen and accepted as the family enforcer, taking on the hard-line ruler role of his grandfather, Prince Philip."

Fordwich added that Harry is "most unlikely to ever release any public apology" given his tell-alls following his royal exit.

"All that has earned him the British nomenclature of ‘Ginger Whinger’ (whiner)," Fordwich claimed.

Harry, who has a strained relationship with his family, rushed to London in February for a very brief visit after the king was diagnosed with an undisclosed type of cancer.

Harry, 39, has seen his father infrequently since the prince quit royal duties in 2020 and moved to California with his wife, Meghan Markle, citing what they said were unbearable intrusions and racist attitudes of the British media. He has since detailed his rocky relationship with his family in TV interviews, a documentary and his memoir, "Spare."

Shortly after his last quick trip to London, Harry told "Good Morning America" that he thought his father’s illness could help bring his family closer.

In "Spare," Harry details his rivalry with William, 42.

In the book, Harry alleged that during an argument in 2019, William called Meghan "difficult" and "rude" and then grabbed him by the collar and knocked him down. Harry suffered cuts and bruises from landing on a dog bowl. Harry claimed Charles implored the brothers to make up. Following the funeral of Charles’ father, Prince Philip, in 2021, the king pleaded, "Please, boys, don’t make my final years a misery."

"Prince William is not as forgiving as King Charles and takes a much more hard-line approach to Prince Harry," British broadcaster and photographer Helena Chard told Fox News Digital.

"He views his brother's behavior as unforgivable," she claimed. "Prince William is adamant that he will protect his family and the monarchy from further upset. Prince Harry has crossed the trust line. For the purpose of damage limitation and to prevent betrayal and trauma, he has cut communication with Prince Harry."

"Prince Harry also caused unforgivable amounts of upset to the much loved and respected late Queen Elizabeth II," Chard continued. "This factor alone is enough for Prince William to freeze Prince Harry out. If Prince Harry hopes to have a relationship/working relationship with the royal family, then he needs to get his skates on as time is creeping on. He will find himself more and more irrelevant to the future of the royal family.

"There are murmurs that Prince Harry hopes to build bridges with his family, but seeing is believing. It is up to him to show initiative and work toward healing the feud, not only behind closed doors but by offering a more public apology highlighting his errors. The statement should also highlight that he will not do or say anything of further detriment which will negatively impact the royal family."

Chard claimed that despite tensions between the battling brothers, the king "has left the door open" for his younger son.

"He is willing to forgive," claimed Chard. "He will not give up on his son."

Doug Eldridge, an agent, celeb branding and marketing expert and the founder of Achilles PR, told Fox News Digital that Harry should issue a public apology to his family – whether William accepts it or not.

"Harry's family is his brand," Eldridge explained. "Unfortunately for him, that was his only talent and claim to fame… To his credit, he worked diligently to build on his family name and his late mother's legacy, but… Harry's brand will never rebound if he doesn't return to his family because that was his brand. The last name. Full stop."

"Sadly, in a somewhat paradoxical sense, Meghan Markle's brand will crater if she backtracks from the allegations and insinuations she made while flicking a match to the royal family," he said about the Duchess of Sussex.

"The nature of the allegations was too severe… His brand will never recover if he doesn't issue an apology; her brand will be dead on arrival if he does. In the end, truth always wins out. When these types of public allegations are made, the truth eventually comes to the fore. If Meghan and Harry were embellishing – much less fabricating – their sympathy-driven tale, neither of them would have an outward-facing future with the public writ large. For all our differences, neither Americans nor Brits have much patience with dishonesty."

KEVIN COSTNER SHARES WHAT PRINCE WILLIAM REVEALED ABOUT PRINCESS DIANA DURING PAST MEETING

Royal expert Ian Pelham Turner claimed to Fox News Digital that as long as there’s gossip of a "Spare" follow-up, the royals may be wary of accepting any peace offerings from Harry.

"The threat of a second ‘Spare’ book is still causing concern," Pelham Turner claimed. "It weighs very heavily on the thoughts of King Charles and Prince William over what further damaging revelations may come out and if it highlights the animosity between Harry and William especially."

"I feel other senior members like Princess Anne and even Prince Andrew may also be extremely concerned about the return of Harry as they fear potential family secrets may be released at any meetings," he claimed. "I feel the way back for Harry and Meghan is to sign a legal peace treaty with the royal family where the couple would agree not to share any more royal secrets. In return, the family will show great public respect to the couple, which has been extremely lacking before."

For Chard, there is still hope that Harry could win over his family – including his no-nonsense brother.

"Prince Harry may be welcomed back into the royal fold in the future if he is genuinely sorry for the hurt his actions have caused, and he works on rebuilding the trust he has lost," she said.

GREG GUTFELD: THE MEDIA BEING SHOCKED OVER BIDEN'S DEBATE PERFORMANCE SEEMS LIKE ANOTHER COVER-UP

GREG GUTFELD: Remember Harvey Weinstein, the sex fiend? So awful. He stood out in an industry where pepper spray is a condiment. Remember what he first said when accused? 

Weinstein said that if you forgave him, his mission would be to send Donald Trump into retirement. He thought that would deflect us away from his depravity. It was a depravity, we found out later, all of Hollywood knew about but ignored, like my script for Bridget Jones' Diarrhea. So either the Weinstein accusations were going to blow up, or Harvey was going to cover his a** with enough Trump hate to beat the rap. 

If it had been up to the media, he would have succeeded. But there were just too many victims and they were talking loudly. Doesn't that sound exactly like what's happening now? Like that scary dog your whole neighborhood hated? 

The Biden dementia story has escaped the yard barking and leaving a trail of poop behind it. And once again, Trump hatred is the weapon of mass distraction. 

GREG GUTFELD: DEMOCRATS AND THE MEDIA HAVE BEEN EXPOSED

What a sanctimonious phony anyway. So you see the Weinstein strategy. We must beat Orange Hitler to permit Joe's awfulness and senility.

Will it work this time? Nope. Confidence in Joe from Scranton is fading like the spray tan on his pinched, empty face. And now, just like Hollywood covering for Harvey because they gain from it. We see that our media has been covering for Joe sagging a**, and theirs too. While Joe disintegrated.

Those of us who called out Joe's incapacity were denigrated or ignored, like Jesse Watters at a nude beach. Meanwhile, The Times, Washington Post, Axios and all the others obsessed on a flag outside Justice Alito's house or endlessly bombarded us with Russian collusion tales and lawfare tales of Jan. 6 insurrectionists. What do all these tales have in common? Trump hate, as distraction.

To the left, it's a giant scandal vaccine. Just keep injecting Trump as Hitler into the narrative and you can cure any bad publicity for the left. The side effect is you lose your hair. But suddenly, now a shocked media is running with this story full blast. After ignoring that, Joe ran his 2020 campaign from his basement that he regularly called a ‘lid’ at 11 a.m. Back in 2019, we saw pictures of his note cards with pre-submitted questions and answers from reporters.

Now, videos once dismissed as right wing cheap fakes are shown as proof by the very same media outlets. But before the debates, they were as bogus as clips of Dana Perino being nice to orphans. True, our president hasn't been running this joint for the last four years, and the media still isn't interested in asking who has. It hasn't been Kamala. She reads to children and their literacy scores drop. The reason for this, I call it award porn. The media learned quickly that to win awards, do nothing but exposes on Trump, and they were handing out Pulitzers for Russiagate exposes like they were shots of Ozempic in 'The View's' green room. But you never win awards for exposing Democrats. That would be like a vampire biting the neck of another vampire.

Meanwhile, the biggest DC scandal of our lifetimes, our president is vegetable adjacent, has been ignored for years. Instead, we got heaping helpings of climate change, police malfeasance, diversity in the military and gender. So why is the media now suddenly feeding on Joe's carcass like Nancy Pelosi on a hijacked blood mobile? Because once the story escaped their electrified fence and ran free in the wild, it became a moneymaker.

The great Joe Biden dementia scandal is suddenly getting the clicks from the general audience, unlike the red soy meat the media usually feeds their left wing base. So now they're just not covering their a****, they're covering their mortgages. So, as our crack reporters tried desperately to paint themselves as noble investigators, they're also trying to get us to believe that Democrats are heroic for turning on Joe.

But you're not a hero when you're caught lying. That's why I had to give back all my BET awards. Suddenly the media, the dems, are all truth tellers. Even Jerry Nadler is questioning Joe's fitness, and he looks like a parade float with a slow leak. Let's not forget the other hoaxes: Fake laptop, Russian collusion, fine people. The media didn't see them as hoaxes because they made them. Well, we didn't miss them. As the old saying goes, I'm the guy doing his job. You must be the other guys.
