King Charles manages to smile as Royals brace for Prince Harry to release MORE bombshells in just hours

KING Charles managed a smile as he walked to church today after his son Harry unleashed a barrage of explosive claims against the Royals - with more bombshells to land tonight.

The King, 74, was this morning pictured beaming as he attended the Sunday service at St Lawrence's Church in Norfolk.

And the head of the Royal Family managed to chat with fans this morning, despite his own son releasing a string of negative claims about the Firm in his upcoming bio.

The Duke of Sussex's bombshell book will hit bookshelves on Tuesday, with excerpts already revealing a torrent of explosive claims against his own family.

Harry's set to unleash another interview on ITV tonight at 9pm - with experts saying his book might be the "final nail in the coffin" for his relationship with his family.

Some of the most damning allegations from Harry include that his brother William, the future king, grabbed him in a brawl - sending him sprawling to the ground and breaking a dog bowl as they argued about Meghan Markle at Nottingham Cottage.

No members of the Royal Family have commented on the book itself, although it was today reported William was "burning with anger".

Charles, who is said to have begged his sons "please boys, don't make my final years a misery", is also yet to comment on his son's tell-all book.

But there have been reports that the King is keen for a reconciliation with Harry, with sources telling it was the only way to avoid "open welfare" for years to come.

One source said: "In many ways, the Royal family is no different to any other family and it will be their normality, rather than their uniqueness, which offers their greatest chance of reconciliation.

“Although Harry resents the role he was dealt within the institution, it is the fact that they are father and son that will bring them back together.”

The fallout from Harry's explosive biography continues as...

• The Duke of Sussex was branded "disrespectful" towards women during a ski trip
• Guests have poured cold water on Harry's claim he wasn't the best man at Prince William's wedding
• Harry's war confession that he killed 25 people has sparked a security threat to Brit troops
• William is said to be "burning with anger" but will stay silent, sources have said

Prince Harry now lives in the US with his wife Meghan and their two children, three-year-old Archie and one-year-old Lilibet, with the family living in their Montecito mansion after quitting Royal life.

And hopes of Prince Harry reconciling with the family have continued to dwindle as more explosive allegations are revealed in excerpts of his book Spare.

In one claim, Duke of Sussex revealed he had begged Charles not to marry his now-wife Camilla - fearing she would become his "wicked" stepmother.

He also claimed his brother William pushed him during a row over Meghan - causing him to fall over and break a dog bowl at Nottingham Cottage.

While much of the biography Spare's contents have been released ahead of its official launch on Tuesday, Harry's sit-down interview on ITV is set to be aired tonight before another US chat with Anderson Cooper.

In a trailer of tonight's interview, the prince revealed he does want to go to his dad's coronation - but insisted "the ball is in their court".

It is understood Harry will discuss Prince William's anger at his relationship with Meghan Markle.

Harry's claims have also seen him take aim at Camilla - shockingly accusing his stepmother of leaking stories about him.

And Kate and Wills have not escaped scrutiny in the explosive bio.

Harry has alleged he got into a physical confrontation with his brother William, saying Wills "grabbed me by the collar, ripping my necklace, and … knocked me to the floor" in an extract of the book reported by 

It's not the first bust-up the brothers have appeared to have had.

The Duke of Sussex said a “steaming” and “shouting” ­William lunged at him in front of Charles after Prince Philip's funeral.

Harry also sensationally claimed Will and Kate encouraged him to wear his notorious Nazi uniform to a fancy dress party, according to a leaked excerpt from his book.

In his biography, the 38-year-old prince says William’s pals Thomas van Straubenzee and James Meade were the real best men at his wedding.

Harry said he pretended to fulfil the role and accompanying William to Westminster Abbey was a “bare-faced lie”.

Spare, out January 10, reveals Harry has taken cocaine, cannabis, magic mushrooms and even used laughing gas while Meghan was giving birth.

And one royal author, Christopher Andersen, said: "It's impossible to imagine that Harry's book won't just be another nail in the coffin of his relationship with the rest of the royals. It might be the final nail in the coffin.

"If Harry really wants his father and brother back in his life, he has a very peculiar way of showing it."

The full 90-minute ITV interview, filmed in California, will air at 9pm today.
