Why King Charles Is Still Going to Washington Despite the Political Storm

King Charles III is going ahead with a state visit to the United States next month, despite calls for the ceremonial event to be called off due to U.S. President Donald Trump's repeated criticism of the British government for failing to support the war in Iran. The decision, confirmed by Buckingham Palace on Tuesday, has reignited a sharp debate inside Westminster about Britain's diplomatic posture, its submission to American pressure, and the constitutional limits of the monarchy's role in foreign policy.

For anyone who has watched the UK-U.S. relationship through multiple administrations, as I have, this moment is not simply about a royal itinerary. It is a stress test of the so-called "special relationship" at one of its most fractured points in modern history.

What the State Visit Involves and When It Will Happen

Buckingham Palace confirmed that Charles's visit will "celebrate the historic connections and the modern bilateral relationship between the United Kingdom and the United States, marking the 250th anniversary of American Independence." Trump confirmed the dates as April 27 to 30, saying on Truth Social: "I look forward to spending time with the King, whom I greatly respect. It will be TERRIFIC!"

The visit is likely to involve all the trappings of a U.S. state visit to the White House, including Guards of Honour and a formal banquet with speeches. The U.S. Ambassador also confirmed that King Charles has been asked to address both houses of the U.S. Congress. The last time a British monarch did that was in 1991, when Queen Elizabeth spoke in Washington D.C. during a state visit as a guest of President George H.W. Bush.

Charles has visited the U.S. 19 times, but this will be his first state visit to the country since becoming king. He will also travel to Bermuda in conjunction with the U.S. trip, his first visit to the overseas territory as monarch.

How This Visit Was Arranged: The Diplomacy Behind the Scenes

The visit came about after Prime Minister Keir Starmer hurried to Washington in February 2025, just five weeks after Trump began his second term, and hand-delivered the king's invitation to the president. It was the first time any world leader received the honor of a second state visit, and the first time the invitation was delivered in a personal letter from the king, which Trump proudly displayed for TV cameras.

Starmer's approach showed how his government planned to handle the U.S. president in his second term: play to his penchant for flattery and royalty, and hope to reap rewards, from a lower tariff rate than that slapped on the European Union, to continued U.S. support for Ukraine.

That strategy worked, for a while. The September 2025 state visit that Trump made to the UK was considered a diplomatic success. Now the return leg of that diplomatic exchange is arriving in a very different climate.

Who Is Criticizing the Visit and Why

Opposition Politicians in Parliament

The loudest dissent has come from the Liberal Democrats. Ed Davey, leader of the opposition Liberal Democrats, said Starmer had shown "a staggering lack of backbone" by allowing the state visit to go ahead, adding that sending the king to the U.S. after Trump dismissed the Royal Navy as "toys" was a humiliation and a sign of a government too weak to stand up to bullies.

Former U.K. Prime Minister Liz Truss slammed Starmer for his reluctance to support the U.S. war in Iran, saying Britain had ended up in a position where it was not acting alongside its most important ally.

Concern Within Labour's Own Ranks

Emily Thornberry, a Labour member of Parliament, articulated the concern shared by many government-side lawmakers when she said the last thing anyone wanted was for His Majesty to be embarrassed.

Trump has called British aircraft carriers "toys" and told the U.K. not to bother sending Royal Navy help. If any such comments were made in the king's presence, it would be particularly embarrassing given that Charles is commander in chief of the UK military, and one of those carriers is named after his late mother, Queen Elizabeth.

Public Opinion Signals Growing Resistance

A YouGov poll published Thursday found nearly half of British citizens opposed the visit to the U.S., with only a third saying it should go ahead. That is a striking indicator of how far public sentiment has shifted, and it puts additional pressure on a Starmer government already navigating significant headwinds.

What the U.S. Side Says: Why Washington Wants the Visit to Proceed

Washington's envoy to the U.K., Ambassador Warren Stephens, said it would be a "big mistake" to cancel King Charles III's planned state visit. When asked about calls to abandon the trip over the Middle East war, he said clearly that he thought it would be a very big mistake.

Trump himself has repeatedly signaled enthusiasm. At a news conference at the White House, Trump said that once his "magnificent ballroom" was completed, it would be used during visits from foreign heads of state, citing the king as an imminent example. At a bilateral Oval Office meeting, Trump told reporters that Charles would visit "very shortly."

Why the King Cannot Simply Refuse to Go

This is the constitutional dimension that much of the public debate has missed. King Charles travels on government advice, so it is not within his gift to cancel the trip. That decision rests with Sir Keir Starmer. The monarch hosts state visits at home and travels abroad at the request of the elected government, which uses the pomp and circumstance of such occasions to bolster relations with countries around the world.

In other words, the king is the instrument of a policy decision made in Downing Street. Blaming or shielding the monarch from this controversy misunderstands how the British constitutional system actually operates.

The Iran War Context: What Britain's Position Actually Is

Although Starmer has faced criticism both abroad and at home for his perceived caution over British support for the U.S. war against Iran, many of his domestic opponents have since reversed their own positions. Nigel Farage, the leader of the Reform UK party, initially called for Britain to stand with America and Israel but, after realizing that Trump's war is intensely unpopular, has since said Britain should not get involved in another foreign war. Kemi Badenoch, the leader of the opposition Conservative Party, also initially supported joining the U.S.-Israeli offensive before shifting her stance.

This reversal by opposition leaders reveals the political calculation at play. The Iran war is deeply unpopular with the British public, and any party seen as too closely aligned with Trump's military campaign risks electoral punishment. Starmer's cautious positioning, while attracting Trump's fury, may in fact be the more sustainable domestic political posture.
