Buckingham Palace announced Tuesday that King Charles will travel to the United States in late April for a state visit, a high-profile trip British officials hope will help mend relations with President Donald Trump following tensions over the Iran war.
The king and Queen Camilla are scheduled to take part in a previously arranged visit marking the 250th anniversary of American independence from Britain, after which they will continue on to Bermuda.
“Their majesties’ program will celebrate the historic connections and the modern bilateral relationship between the United Kingdom and the United States,” Buckingham Palace said, noting that the visit is being undertaken at the recommendation of the British government.
The trip will mark the first state visit to the United States by a British monarch since 2007, when Queen Elizabeth II — Charles’ mother — made her fourth official visit during her reign.
According to reports, King Charles III is expected to address a joint session of Congress during the visit, highlighting the enduring relationship between the two nations as the U.S. commemorates its milestone anniversary.
Relations between Trump and British Prime Minister Keir Starmer have come under strain in recent weeks, largely due to the U.K.’s reluctance to take a more active role in the Iran war and its refusal to allow American forces to launch initial strikes from British bases.
Although Britain has since permitted what Starmer described as defensive operations, Trump has openly criticized the prime minister, saying he was “not Winston Churchill” and accusing him of weakening the long-standing alliance between the two countries.
Trump has also dismissed Britain’s offer to contribute additional military resources to the region.
Beyond the Iran conflict, disagreements have emerged over Britain’s agreement with Mauritius to transfer sovereignty of the Chagos Islands, where the joint U.S.-U.K. Diego Garcia air base is located. Trump has called the arrangement a serious error, a stance welcomed by some of Starmer’s political opponents.
Starmer, who previously worked as a human rights lawyer, has questioned the legality of the military campaign against Iran — a position that has resonated with segments of the British public concerned about rising energy costs and the broader consequences of the conflict.
Despite those concerns, Starmer has refrained from directly attacking Trump and has maintained publicly that relations between the two leaders remain positive.
Since Trump returned to office, the British government has leaned on the monarchy’s diplomatic influence to help maintain goodwill with the White House. Trump has expressed strong admiration for the royal family, and officials hope that connection can help preserve cooperation on issues such as the war in Ukraine and potential trade disputes.
Charles previously hosted Trump for a rare second state visit to the United Kingdom last September, which included a ceremonial carriage procession and a formal banquet at Windsor Castle. During that visit, Trump praised the relationship between the two countries, calling it “irreplaceable and unbreakable.”
British officials are now looking to the 77-year-old monarch to once again help stabilize the relationship during a period of friction. Prince William is also expected to visit the United States later in the year during the soccer World Cup.
Trump said last week that the upcoming visit would proceed despite the tensions with Starmer. “He’s a friend of mine,” Trump said of Charles. “He’s a great gentleman.”
The visit, however, could place the king in a delicate position, requiring him to publicly engage with a U.S. president who remains unpopular among many British voters.
There are also policy differences between the two leaders, particularly on climate change, an issue Charles has championed for decades but where Trump has taken a markedly different stance.
In addition, Charles may face renewed scrutiny over his brother, Andrew Mountbatten-Windsor, who is currently under police investigation for alleged misconduct tied to his association with the late Jeffrey Epstein.
Some political figures in Britain have already voiced opposition to the visit. Ed Davey, leader of the Liberal Democrats, has previously argued that the trip should be canceled, saying Trump should not be rewarded diplomatically given his past criticisms of the United Kingdom.
