King Charles’s four-day state visit to the US is going ahead as planned, after a shooting at the White House correspondents’ dinner raised doubts about security. The royal trip, which coincides with the 250th anniversary of American independence, is the first since 2007, when the late Queen Elizabeth II was hosted by President George W. Bush.
State visits are formal, international visits made by the heads of state, which in the UK is the king. In September 2025, the king hosted an inbound state visit for US President Donald Trump. Now, he and Queen Camilla will head to Washington DC, New York and Virginia.
The visit, which runs from April 27 to 30, has been controversial amid tensions between the White House and Downing Street. Trump has repeatedly criticised Keir Starmer over a lack of support for the US military operation in Iran. Trump’s threats to buy Greenland, and capture of Venezuela’s president Nicolás Maduro, have also received varying levels of criticism from the UK government.
Trump has also called the UK’s plan to cede sovereignty of the Chagos Islands to Mauritius an “act of great stupidity”, and reports suggest the US is reviewing its position on Britain’s claim to sovereignty of the Falkland Islands.
Diplomacy between the two countries is currently at an “all time low”, according to former Labour defence minister and Nato secretary general Lord Robertson. Lib Dem leader Ed Davey has called for the visit to be cancelled, and Emily Thornberry, chair of the foreign affairs select committee, has said it should be delayed while the war in Iran is ongoing.
In addition, the visit is difficult for the king personally. Charles’ brother, Andrew Mountbatten-Windsor, was a close associate of the convicted sex offender Jeffrey Epstein. The king has been urged to meet with Epstein’s victims. No such meeting is currently scheduled, although the queen is due to meet representatives of campaigns against violence against women.
The final decision over whether to cancel or proceed with a state visit lies with the government, not the king. It is constitutional convention that the monarch must ultimately accept the advice of the prime minister.
Indeed, the Buckingham Palace press release announcing the visit stated that it would take place “on advice of His Majesty’s Government”. This specific wording is rare – usually, there is no explicit mention of state visits being made on the advice of the government. Given Trump’s respect for the royal family, Starmer’s government likely sees this visit as a necessary opportunity to ease UK-US tensions.
How are state visits arranged?
Both inbound and outbound state visits are coordinated by the UK Royal Visits Committee (RVC), which is comprised of Cabinet Office officials. They pass the RVC’s recommendations to the prime minister, who offers formal advice to the monarch. The king’s representatives attend RVC meetings.
According to the 19th-century constitutional historian Walter Bagehot, the monarch has “the right to be consulted, the right to advise, and the right to warn”. This seems to at least give the monarch a bit of discretion over details of their state visits.
George VI – the first reigning British monarch to make a state visit to the US, in 1939 – made some changes to the itinerary originally presented to him, including requesting not to address Congress due to his stammer.
Following talks with the White House, Buckingham Palace have reportedly made some “modest operational adjustments” to a few engagements during this visit due to security concerns sparked by the shooting at the correspondents’ dinner.
Tricky political climate
It is not unusual for political events to cast a shadow over state visits. Queen Elizabeth II’s first US state visit took place amid the Suez crisis. Her presence helped to “preserve the special relationship” at a time when it was being tested like never before.

Ahead of the US bicentennial celebrations in 1976, the British ambassador in Washington even warned against sending the queen to Washington due to political events. Amid the Watergate scandal, there was “a very real chance not only of embarrassment to Her Majesty, but of impairment to the dignity of the monarchy”. The RVC suggested that Charles, then Prince of Wales, should go instead.

The British government has long referred to state visits as their “big gun” thanks to the popularity of the monarchy and the symbolic power of a state visit.
Trump is known to admire the British royal family, describing the king as a “fantastic man”. Recent history suggests the king may even be one of the few people to whom Trump is willing to listen.
Just a week after visiting Windsor Castle in September 2025, the president went from urging Kyiv to make territorial concessions to insisting, at the UN General Assembly of Nations, that it could win back all of the territory captured by Russia since 2022. According to Volodymyr Zelensky’s chief of staff, King Charles was a “key influence” on this shift.
Most recently, private comments made by the king to the president were said to have encouraged Trump to backtrack from his comments about British soldiers “staying back” from the front lines in Iraq.
The king will address both houses of Congress and deliver a speech at the state banquet. These diplomatically chosen words, which are likely to have been carefully written for him by the government with the involvement of royal aides, will provide opportunities for him to quell the tensions of recent months. The government will hope that – just as Trump has claimed it can – the king’s visit will “absolutely repair” UK-US relations.
