United Kingdom King Charles III will visit the United States this month to address American lawmakers, United States House Speaker Mike Johnson announced on Wednesday, April 1.

The trip will mark the first state visit by a British ruler since ‌2007, when Charles' mother ​Queen Elizabeth made ​what was the ​fourth such U.S. trip ‌of her reign.

In a statement post on X, Johnson said the king had been invited to address U.S. Congress ‌on April 28 during his ‌visit to Washington D.C.

In a separate statement released one day earler, Buckingham Palace announced Queen Camilla will accompany the king, and said the "long-planned" trip came on the advice of the British government and, "at the invitation of The President of the United States."

"Our two nations share one of the most consequential partnerships in history, and together we will mark the historic milestone of America’s 250th year of independence," Johnson wrote in a post on X.
