King Charles is preparing to host former U.S. President Donald Trump and First Lady Melania Trump at Windsor Castle in September for a rare second state visit to the United Kingdom. The invitation, extended earlier this year after Trump’s election victory, was personally delivered by UK Prime Minister Keir Starmer during a February Oval Office meeting. Originally planned for a later date, the visit was moved up by Starmer, reportedly overriding the King’s initial timeline.
While King Charles initially suggested venues in Scotland—either Balmoral Castle or Dumfries House—the location was later changed to Windsor Castle after palace aides reviewed the formality and symbolism required. A formal invitation, the Manu Regia, hand-signed by the King, was sent to Trump at the White House last week. The palace confirmed that the monarch has known Trump for years and looks forward to the visit.
Trump accepted the invitation without hesitation, calling the opportunity “really special” and “unprecedented.” Starmer hailed the occasion as a testament to the strong U.S.–UK relationship, referencing Trump’s successful 2019 visit under Queen Elizabeth II. Trump responded warmly, saying it would be an honor to visit again and to pay respect to the King and the UK.
Despite the ceremony and diplomacy, international tensions remain. Trade disputes between the U.S. and Canada have worsened, particularly after Trump suggested Canada could become the “51st state.” In response, Charles made a symbolic visit to Canada in May, where he reaffirmed the nation’s independence during a historic opening of Parliament—the first by a reigning monarch since 1857.
Meanwhile, speculation continues about a potential royal visit to the United States, possibly in 2026. Though still in early discussion, it would mark another milestone in modern royal diplomacy. Trump has consistently expressed admiration for the royal family, saying he “loves King Charles.”
This upcoming visit is especially notable because no elected U.S. leader has received two state visits from the UK. Only two non-U.S. leaders—Queen Margrethe II of Denmark and King Olav of Norway—have received the honor twice. However, escalating trade disputes may cloud the celebratory tone of the upcoming state visit.
