Watch live as King Charles III uses a historic speech to Congress on Tuesday (28 April) to praise the US and UK's relationship against a backdrop of global uncertainty, as he and the Queen begin their state visit.
The King will use his address to say that the story of the UK and US since America’s independence is “one of the greatest alliances in human history” where the two nations find ways to “come together”.
Charles's speech to both Houses is likely to be seen as acknowledging tensions between Donald Trump and Sir Keir Starmer, who have clashed over the US leader’s war against Iran.
It marks only the second time a British monarch has addressed a joint meeting of Congress, the first being the late Queen Elizabeth II in 1991.
His Majesty is also expected to make brief reference to the shooting at the White House Correspondents' Dinner attended by the US president on Saturday night and in a show of solidarity and support offer “the highest regard and friendship of the British people to the people of the United States” on the 250th anniversary of American independence.
Earlier on Tuesday, Charles and Camilla were honoured with a ceremonial welcome to the White House.
During a speech on the south lawn, Trump told the King that his mother had a crush on him as a young Prince Charles.
