King Charles III highlighted the crucial bonds between the United Kingdom and France in the face of a “multitude of more complex threats,” as he welcomed President Emmanuel Macron for the first state visit by a European leader to his country since Brexit.

In July 2025, after French President Emmanuel Macron made a state visit to the U.K., a claim (archived) circulated online that Macron broke royal protocol when he walked in front of King Charles III while inspecting British troops on July 8.

Donald Trump will visit the UK for a rare second state visit in September, after accepting an invitation from King Charles III to be hosted at Windsor Castle, Buckingham Palace said.
