President Donald Trump has made clear he was looking forward to the four-day state visit by King Charles III and Queen Camilla to the White House, offering repeated praise for the king and calling him a friend. The visit, timed to mark the 250th anniversary of American independence, went ahead after a last-minute security review following a Saturday-night shooting at the White House Correspondents’ Dinner; officials said the monarchs’ itinerary was largely unchanged.
Despite the warm rhetoric, political tensions shadow the visit. The most notable dispute concerns the Iran conflict: Mr. Trump has publicly criticized the United Kingdom for not joining the U.S. and Israel more directly and has at times mocked Prime Minister Keir Starmer for his reluctance to commit British forces. London has allowed American use of bases on British territory related to the Iran operations, but Starmer has repeatedly stated “this is not our war” and expressed frustration at its domestic impact. Those differences highlight a shifting dynamic in U.S.-U.K. relations.
Other flashpoints include the U.K.’s plan to cede the Chagos Islands to Mauritius — a group that includes an island hosting a U.S. air base — which drew sharp criticism from Mr. Trump. He also pushed for expanded oil and gas drilling licenses in the North Sea and threatened tariffs in response to Britain’s proposed digital services tax on tech companies.
The king and queen are expected to remain politically neutral during their time in Washington and will not take part in policy debates. Nevertheless, the royal couple represents an element of British soft power that could resonate with Mr. Trump, who has personal ties to the U.K.: his mother was born in Scotland, and he has spoken warmly of past encounters with the royal family.
King Charles will address a joint session of Congress, becoming only the second British monarch to do so. When Queen Elizabeth II spoke to Congress in 1991 she emphasized democracy, international cooperation and multilateral institutions such as the U.N. and NATO, and praised U.S.-U.K. cooperation during the Gulf War. Buckingham Palace said the king’s address will touch on issues where the two countries currently diverge, including NATO, while seeking to renew and strengthen the bilateral relationship.
Against a backdrop of disagreements over alliances and military commitments, the visit is being watched as both a ceremonial reaffirmation of ties and a test of whether personal rapport between leaders can help smooth broader policy differences. During their visit the king and queen also toured the White House grounds, including the South Lawn garden and its beehive, underscoring the ceremonial and symbolic aspects of the trip.
