Buckingham Palace said King Charles III was "shocked and saddened" to find out a British soldier died after a fall at a horse show the royal was attending this week.

The soldier died during a display of the King’s Troop, Royal Horse Artillery at the Royal Windsor Horse Show on Friday evening.

The unidentified soldier fell after leaving the arena following the display, and despite being treated, their injuries were serious, and they died at the scene, the Thames Valley Police said in a release.

The police said the horse show would continue as planned on Saturday but without another display of the King’s Troop, Royal Horse Artillery.

Charles attended the horse show, which is on the grounds of Windsor Castle, along with his younger brother Prince Edward, the Duke of Edinburgh, and his wife Sophie, the Duchess of Edinburgh, their daughter Lady Louise, who was working at the show, and the king's sister Princess Anne.

Following the soldier's death, the king met with members of the King’s Troop at the horse show after returning on Saturday.

"While His Majesty and other members of the royal family were present at the arena at the time the incident took place, they were not made aware of the severity of the situation until later," a Buckingham Palace spokesperson said, according to the London Times.

The spokesperson added, "The King was greatly shocked and saddened to have learned subsequently of the troop member’s death and will be in touch with the family to share his personal condolences. The thoughts and most heartfelt sympathies of the whole royal family are with the victim’s loved ones and military colleagues at this time of grief."

Buckingham Palace did not immediately respond to Fox News Digital’s after-hours request for comment.

The annual horse show is the only time the private grounds of Windsor Castle are open to the public.

On Saturday morning, the police appealed to the public for any information about the "unexplained but non-suspicious death" of the soldier.

"At this stage, we have not found any suspicious circumstances," police said in a post on Facebook. "We are working with the British Army, Ministry of Defence, the Defence Accident Investigation Branch and Royal Windsor Horse Show organisers HPower to gather as much information as possible to understand how this happened."

A 39-year-old man pleaded not guilty on Friday to threatening former Prince Andrew near his new home on the royal family’s Sandringham estate.

Alex Jenkinson, 39, is accused of using threatening, abusive or insulting words or behavior toward the former prince, whose royal titles were removed last year by King Charles III due to his connections to Jeffrey Epstein.

Jenkinson, who faces two counts, is accused of threatening Andrew on Wednesday and another man on Tuesday.

The former Duke of York is also expected to give evidence in the trial, which is set for July 29 at the Westminster Magistrates' Court.

Andrew was allegedly yelled at by a masked man while walking his dogs near his home, the Daily Telegraph reported.

"Officers attended, and the man was arrested on suspicion of a public order offence and possession of an offensive weapon," the police statement said.

The incident comes three months after Andrew Mountbatten-Windsor, as he is now known, was arrested, himself, on suspicion of misconduct in public office connected to his Epstein ties and his time as the U.K. trade envoy.

Andrew moved to Sandringham earlier this year after he was asked to vacate his home at the Royal Lodge in Windsor.

Virginia Giuffre, Andrew’s main accuser, claimed that she was forced to have sex with the royal three times starting when she was 17 years old.

Andrew has denied all of the accusations against him, but settled with Giuffre in 2022 over her civil sexual assault lawsuit. She later died of suicide in 2025.

Jenkinson appeared in court remotely from King's Lynn Police Investigation Centre in Norfolk on Friday with his arm in a sling.

He did plead guilty to failing to provide specimen of blood while in custody.

Jenkinson was released on bail on the condition that he doesn’t enter the county of Norfolk, attempt any contact with Andrew, and he must stay 500 meters away from Sandringham, Buckingham Palace, Balmoral Castle, Windsor Castle and Highgrove.

Leaked remarks from Britain’s ambassador to the U.S. suggesting Washington’s "one true special relationship" is with Israel — not the United Kingdom — have sparked political backlash in London.

Sir Christian Turner reportedly told a group of British students earlier in 2026 that the United States’ one true "special relationship" is "probably Israel," not the United Kingdom, according to leaked audio first reported by the Financial Times. 

The remarks, made privately but leaked publicly during King Charles III and Queen Camilla’s high-profile visit to Washington and New York amid efforts to repair strained relations, have placed fresh scrutiny on Britain’s standing in Washington at a particularly sensitive diplomatic moment.

Turner reportedly stressed that Britain’s ties with the U.S. remain deeply intertwined, particularly on defense and security. 

'TRUMP EFFECT' ON DISPLAY AS UK'S STARMER BOOSTS DEFENSE SPENDING ON EVE OF US VISIT

"There is a deep history and affinity between us. Particularly on defence and security, we are intertwined," according to leaked audio cited by British media. "The relationship will carry on, if you want, being ‘special,’ but I think it’s going to have to be different." 

Turner also said, according to the transcript, that Britain and Europe must "work to redefine" their relationship with Washington, particularly in terms of defense, rather than relying on a U.S. security umbrella. 

The leak comes after recent strains between Trump and British Prime Minister Keir Starmer, including disagreements over Britain’s posture toward U.S.–Israeli military action against Iran. Trump previously criticized Starmer publicly, saying he was "not Winston Churchill."

An embassy spokesperson and a U.K. Foreign Office spokesperson sought to distance the government from the leaked remarks, telling Fox News Digital: "These were private, informal comments made to a group of U.K. sixth-form students visiting the U.S. in early February. They are certainly not any reflection of the U.K. government’s position."

The wide-ranging informal discussion, the spokesperson explained, focused on diplomacy and the political issues of the day that students asked questions about, stressing that the remarks were clearly never intended as on-record statements of government policy.

PRINCE WILLIAM VIEWS TRUMP RELATIONSHIP AS KEY TO MONARCHY'S FUTURE: EXPERT

Still, the controversy raises broader questions that extend beyond diplomatic optics: whether the symbolic "special relationship" between Washington and London has been eclipsed by more immediate U.S. strategic priorities, particularly Israel’s central role in American Middle East security calculations.

Barak Seener, senior fellow at the London-based Henry Jackson Society, said Turner’s remarks reflected a hard strategic reality rather than a diplomatic blunder.

"Ambassador Christian Turner was giving a realistic assessment that echoed President Trump’s criticism of NATO, calling it a ‘paper tiger’ for not contributing to joint U.S.-Israel-led operations against Iran," Seener told Fox News Digital.

Seener pointed to his recent report, "Israel 2048: A Blueprint for an Asymmetric Geopolitical Power," arguing that Israel’s expanding military capabilities increasingly function as a force multiplier for U.S. regional interests. By contrast, Seener argued, Britain’s modern strategic value has weakened despite its historic rhetoric.

"King Charles, in his recent speech to the U.S. Congress, was forced to emphasise the U.K. and U.S.’s shared culture and history rather than recent military contributions simply because the U.K.’s naval and military capabilities have been completely hollowed out," Seener said.

He added that Charles’ invocation of past joint sacrifices "does not bear any relevance to today" given Britain’s reported refusal to allow U.S. use of Royal Air Force bases for strikes on Iran.

The White House, however, emphasized continuity over controversy, telling Fox News Digital that, "President Trump has enjoyed welcoming Their Majesties to the White House this week, including yesterday morning, when he highlighted the historic, special relationship between the United States and the United Kingdom," White House spokesperson Anna Kelly said.

"The events of this visit are unprecedented in scope and spectacle, and the President enjoyed hosting a beautiful State Dinner yesterday evening," she added.

As Britain publicly distances itself from President Donald Trump’s Iran pressure campaign, King Charles III’s upcoming visit is shaping up as more than royal pageantry. 

It may be Britain’s most important diplomatic tool for preventing growing policy fractures with Washington from becoming something deeper.

"The British monarch has historically had huge importance in terms of creating personal diplomacy to smooth over ruffled feathers," Alan Mendoza, executive director of the Henry Jackson Society, a London-based think tank, told Fox News Digital, arguing that the crown has often served as Britain’s strategic stabilizer during moments of political strain.

Mendoza said Charles could play a critical role at a moment when Britain's Prime Minister Keir Starmer’s government and Trump appear increasingly divided over Iran, defense strategy and the future shape of the transatlantic alliance.

TRUMP SLAMS STARMER AS ‘NOT WINSTON CHURCHILL’ FOR REFUSAL TO BACK IRAN STRIKES

"King Charles has the opportunity, through personal diplomacy, to create a new beginning with Donald Trump," Mendoza said.

Britain’s balancing act became clearer Monday when Deputy Minister Stephen Doughty publicly rejected U.S. blockade tactics against Iran, while still backing Washington’s broader effort to secure maritime traffic through the Strait of Hormuz.

"While the U.K. doesn’t support the U.S. blockade, it supports working with the United States and others to reopen the Strait of Hormuz," Doughty said ahead of a U.N. Security Council meeting, according to The Associated Press, warning Tehran cannot be allowed to hold "the rest of the world to ransom."

The split underscores London’s effort to support U.S. security goals without fully endorsing Trump’s "economic fury" strategy, which aims to strangle Iran’s economic lifelines through aggressive maritime pressure.

That policy divergence has intensified scrutiny over whether Charles’ visit is now functioning as a diplomatic pressure valve.

A White House spokesperson emphasized the visit as a sign of enduring personal rapport between the president and the monarch. "President Trump has always had great respect for King Charles, and their relationship was further strengthened by the president’s historic trip to the United Kingdom last year," White House spokesperson Anna Kelly told Fox News Digital. "The president enjoyed welcoming their majesties to the White House, and he looks forward to more special events throughout the week."

AS AIRSTRIKES RAIN DOWN ON THE IRANIAN REGIME, CAN A FRACTURED OPPOSITION UNITE TO LEAD IF IT FALLS?

Mendoza pointed to Queen Elizabeth II’s past interventions as evidence that the monarchy can sometimes succeed where elected leaders cannot.

He cited Elizabeth’s historic role in easing tensions with Ireland and described royal diplomacy as uniquely positioned to create trust at the personal level.

"People often wonder why the British monarchy still exists in the 21st century," Mendoza said. "This is why."

Still, Mendoza was careful not to overstate the king’s role.

Charles, he said, is unlikely to directly influence specific policies on Iran, NATO or military cooperation. Instead, his greatest value lies in shaping what Mendoza called the "general mood music" around Trump’s willingness to engage.

"It’s more a question of general mood music, which could make the president more receptive to interesting solutions," Mendoza said.

That distinction may prove crucial.

Rather than forcing policy alignment, Charles could help preserve the broader strategic atmosphere needed to keep Washington and London functioning as close allies even while their elected governments disagree.

KING CHARLES SENDS PERSONAL MESSAGE OF CONGRATULATIONS TO TRUMP ON SWEARING-IN

For Britain, that may be particularly important as outside analysts warn that the "special relationship" is under mounting structural strain.

In an analysis published Monday, Council on Foreign Relations senior fellow Matthias Matthijs argued that while the royal visit offers "spectacle and ritual," it is unlikely to reverse what he described as the deeper unraveling of U.S.–U.K. ties.

Matthijs pointed to Trump’s repeated criticisms of Starmer about immigration, energy policy and Britain’s posture toward the U.S.-Israeli confrontation with Iran, suggesting Charles may now be doing much of the diplomatic "heavy lifting" required to preserve British access to Trump.

Meanwhile, constitutional scholars in Britain have also raised concerns.

Writing for the U.K. Constitutional Law Association earlier in April, Francesca Jackson warned that using the monarch as a diplomatic instrument during periods of sharp political volatility could expose the Crown to political backlash or "potential embarrassment," especially if Charles is perceived as caught between Trump and Starmer.

That risk reflects the broader stakes.

If Trump embraces Charles while continuing to criticize Starmer, the visit could preserve royal rapport while underscoring political dysfunction, effectively creating a parallel diplomatic lane between Washington and the British Crown.

But for now, Mendoza argues, the monarchy’s purpose is not governance, but access to the king, which may still have a chance to keep the relationship from fracturing beyond repair.
