New Documents Reveal King Charles' Serious Reservations About Hosting Donald Trump at Windsor Castle
The King’s reported concerns came to light through the so-called Mandelson files, a series of heavily redacted documents containing hundreds of private messages and emails.
King Charles's visit to the U.S. last month quickly became one of the most memorable milestones of his reign. It followed a 2025 state visit to the U.K. by US President Donald Trump and First Lady Melania Trump, who stayed with Charles and Queen Camilla at Windsor Castle. But a recent report has revealed that the King hesitated over hosting Trump, raising concerns among government officials that it could lead to a major ‘diplomatic crisis.’
According to iPaper, a source said that Charles was reportedly "reticent" about hosting Trump, and the King simply "did not want to do it." The reported hesitation was said to be linked to Trump's controversial meeting with Ukrainian President Volodymyr Zelensky at the White House in February 2025. What began as a diplomatic visit quickly escalated into a tense public clash inside the Oval Office.
During the tense exchange, Trump and Vice President JD Vance accused Zelensky of being "disrespectful" and urged him to accept a proposal to end the conflict with Russia. Trump also warned that the U.S. could pull its support for Ukraine entirely. The fallout was immediate: a planned joint press conference was abruptly canceled, a vital minerals agreement collapsed, and Zelensky cut his White House visit short after the talks broke down.
The events of the Zelensky meeting reportedly influenced Charles' view of the visit, with the King said to have reservations about hosting Trump. Those concerns created a challenge for government officials, as per the outlet, who worried that tensions could spiral into a "full-blown diplomatic crisis" if the visit did not go ahead as planned. The report said, “The monarch’s private reservations over the visit left officials scrambling, fearful that a royal snub of President Trump could detonate into a full-blown diplomatic crisis.”
The King’s reported concerns came to light through the so-called Mandelson files, a series of heavily redacted documents containing hundreds of private WhatsApp messages and email exchanges between Peter Mandelson, cabinet ministers, senior civil servants, and advisers. The release of these records aligned with a wider parliamentary inquiry evaluating the scrutiny applied during Mandelson’s appointment as ambassador. The diplomat's past relationship with convicted s*x offender Jeffrey Epstein drew intense focus, particularly amid reports that Mandelson continued his association with Epstein well after his 2008 criminal conviction.
Whatever concerns may have existed beforehand, they did not stop the visit from going ahead. Trump received a full royal welcome at Windsor Castle in September 2025, where he joined Charles for several ceremonial events and a state banquet.
