A palace spokesperson reassured: “There is no cause for concern.”
King expected to highlight global threats and shared values in state banquet speech

Later in the day, the King was set to deliver a formal speech during a state banquet in Macron’s honour — focusing on the evolving alliance between the UK and France.
According to advance reports, Charles would acknowledge the many “complex threats” facing both nations, warning that such challenges “know no borders” and require cross-national cooperation. He is expected to affirm the shared values and historic ties between Britain and France, while also expressing admiration for France’s cultural and political achievements.
The visit is being viewed as a symbolic step in strengthening post-Brexit diplomatic relations between the two neighbours.

Despite his ongoing health challenges, King Charles has continued to uphold a steady schedule of public engagements. And while Tuesday’s appearance drew momentary concern, the palace’s swift clarification helped settle public unease — allowing the focus to return to matters of diplomacy and partnership.
