LONDON – King Charles III heads to the United States on April 27 with transatlantic tensions over the Iran war and the Epstein scandal’s long shadow threatening to intrude on the landmark visit.
Both Buckingham Palace and the British government have said the four‑day trip will honour the historic relationship between the two countries as the US marks 250 years of independence.
King Charles’ first US state visit as monarch comes at the request of the British government and President Donald Trump and will be made with Queen Camilla, according to the palace.
However, as the American leader’s war with Iran drives a rare wedge between London and Washington, it has generated considerable controversy.
Mr Trump has repeatedly lambasted British Prime Minister Keir Starmer over his war opposition, alongside his government’s immigration and energy policies.
“This is not Winston Churchill that we’re dealing with,” Mr Trump grumbled in March, adding the so-called special relationship was “not like it used to be”.
The American leader has also mocked the perceived state of Britain’s armed forces – of which the King is commander-in-chief.
In turn, Mr Starmer has stepped up his public criticism of the war, while stressing the breadth and depth of UK-US ties in defending the state visit. An early April YouGov poll found 48 per cent of Britons support cancelling it.
“Often what the monarchy is able to do, through the bonds that they build, is reach through the decades in a situation like this,” Mr Starmer told MPs when asked why the trip was going ahead.
Mr Trump – a vocal admirer of the royals whose mother was Scottish – told the BBC on April 23 the visit could “absolutely” help repair relations, praising the King as “fantastic”.
Britain’s freshly-appointed ambassador to the US Christian Turner, whose predecessor Peter Mandelson was dismissed in 2025 after revelations about his ties to Epstein, said the state visit was “important” for the countries’ ties.
The King’s relationship with the President “is a very personal one, the deep affection and respect they hold”, Mr Turner told NBC News.
King Charles, 77, showcased his diplomatic skills during Mr Trump’s state visit to Britain in September 2025, with Royal Holloway University of London monarchy expert Craig Prescott noting he is “generally very good” at navigating such occasions.
Dr Prescott said the independence anniversary provided a useful “get out” for the British side to argue the trip is “not about Keir Starmer and Donald Trump, per se”.
But he acknowledged it was “that little bit closer to politics” than usual and King Charles would likely address the “very big elephant in the room” in a coded way in his speech on April 21 to the US Congress.
The first British monarch to address Congress since his mother, the late queen Elizabeth II, in 1991, he will mark the two countries’ shared history and deep ties, the palace has said.
“He might refer to how the special relationship has perhaps waxed and waned over time,” Dr Prescott predicted, arguing King Charles has proven to be a “better speaker” than his mother.
But Mr Graham Smith of the anti-monarchy campaign group Republic, argued the king will “go through the rituals without offering anything of substance”.
The only critical thing “about this pointless trip is how Trump behaves”, he said on X.
Meanwhile, the scandal around late US sex offender Jeffrey Epstein threatens to encroach on the highly choreographed tour.
King Charles has faced a major crisis over the friendship his brother Andrew Mountbatten-Windsor had with the late billionaire, who died in prison in 2019.
The longstanding controversy intensified after the former prince Andrew was arrested in mid-February following new revelations over their links.
The King, who stripped his disgraced brother of his titles in October, said “the law must take its course” in a rare personally signed statement.
Mr Mountbatten-Windsor, who remains under police investigation, has not been charged and has denied any wrongdoing.
Several US lawmakers have unsuccessfully urged the ex-prince to testify before Congress about Epstein.
Democrat Ro Khanna wrote to King Charles in March requesting the king meet victims privately, while the family of late Epstein accuser Virginia Giuffre made a similar demand.
Palace sources have told British media a meeting “will not be possible”, arguing it could “impact on (police) inquiries, or the proper course of the law”.
Mr Khanna told The Times in April that declining would make King Charles look “out of touch” and “diminishes the credibility of the monarchy for future generations”.
But he added acknowledging the survivors and their struggle for justice in his Congress address “would go a long way”.
The visit, which will see the royals have tea with Mr Trump and first lady Melania and attend a state dinner, appears meticulously planned to avoid unscripted moments.
Only photographers will capture the April 28 Oval Office meeting between Mr Trump and King Charles, limiting chances for the king to be blindsided by the unpredictable US leader and reporters.
King Charles and Queen Camilla will visit New York on April 29, touring the 9/11 memorial, before departing April 30 for Bermuda for his first visit to a British overseas territory as monarch. AFP
