King Charles III delivers historic address to US Congress amid ongoing state visit

King Charles III has delivered a speech to a joint session of the US Congress, becoming the first British monarch to address the body since Queen Elizabeth II in 1991. This engagement serves as the centrepiece of a four-day state visit to the United States, which officials describe as the most high-profile event of his reign to date. The address reinforces the diplomatic bond between the two nations through themes of shared history and democratic values, echoing the precedent set by the late Queen.

The historic address took place on Tuesday, 28 April 2026, as part of the broader state visit that began the previous day. The visit proceeds with formal ceremonial trappings designed to highlight the strength of the relationship between the UK and the US, even as it unfolds against a backdrop of domestic instability within the United States. Officials frame the engagement as a demonstration that the transatlantic alliance can withstand significant political turmoil and security challenges.

The schedule for the visit remains unchanged despite recent security incidents, specifically a shooting at a White House dinner attended by President Donald Trump on Monday. Buckingham Palace has confirmed that the full itinerary will continue as planned, including the Congress address and a state dinner scheduled to follow the speech later that evening. This decision underscores the institutional commitment to the diplomatic protocol regardless of the immediate security fallout.

Themes central to the King's engagement include shared history and democratic values, which are expected to dominate the discourse similar to previous addresses by Queen Elizabeth II. The visit is characterised by these formal elements intended to underscore the resilience of the alliance amidst current international tensions. While the specific content of the speech is not detailed in the available reporting, the structural significance of the event remains clear within the context of the state visit.

The broader context of the visit includes international diplomatic friction, including a conditional proposal by Iran regarding the Strait of Hormuz. Despite these wider geopolitical pressures and the recent security incident at the White House, the focus remains on the ceremonial reinforcement of the UK-US partnership. The event stands as a notable diplomatic milestone, occurring while the administration navigates ongoing domestic instability.

A state dinner is scheduled to follow the speech later that evening, concluding the day's major activities. The full itinerary, confirmed by Buckingham Palace, ensures that the ceremonial obligations of the state visit are met without interruption. This structured approach to governance highlights the priority placed on institutional continuity and the maintenance of high-level diplomatic channels.
