King Charles III's state visit to the United States took a lighter turn on Tuesday evening when a historic naval gift prompted laughter at a White House dinner.

The King presented a ceremonial bell from the Second World War submarine HMS Trump and delivered a brief joke as he handed it over. 'And should you ever need to get hold of us, just give us a ring,' he said, drawing a warm response from guests.

The moment stood out during an otherwise formal event marking the King's first official visit to Washington since his coronation. While brief, it added a note of humour to a visit largely focused on diplomacy and long-standing ties between the UK and the US.

The bell, originally mounted on the conning tower of HMS Trump, was presented as a symbol of the two nations' shared wartime history. The submarine, a T-class vessel launched in 1944, served in the Pacific and later operated with the Fourth Submarine Squadron in Australia, where British and allied forces worked closely during the final stages of the war.

During the presentation, the King described the artefact as 'a testimony to our nation's shared history and shining future', linking the vessel's service to the modern alliance between the two countries.

Its name also caught attention. Thecoincidence with US president Donald Trumpwas not lost on those in the room, and the reaction briefly broke the usual formality of the occasion.

State visits are usually tightly choreographed, with speeches carefully prepared and approved in advance by officials on both sides. Even small remarks are often reviewed ahead of time, reflecting the sensitivity of diplomatic settings.

The King's comment appeared to offer a rare moment of flexibility within that structure, acknowledging the situation without straying from diplomatic norms. Guests, including senior officials and diplomats, appeared to share the joke, with the response cutting through the otherwise formal tone of the evening.

HMS Trump was part of a class of Royal Navy submarines used in the later stages of the Second World War. Built at the Vickers-Armstrongs shipyard in Barrow-in-Furness, it carried out patrols in the Pacific before being modified after the war to improve performance.
