The King and Queen Camilla arrived at the White House on the second day of their US state visit.
US President Donald Trump and his wife First Lady Melania Trump greeted the royals, with images showing them smiling as they shake hands.
Crowds applauded as Trump made a speech, praising the historical closeness of the UK and US. He said Americans have had “no closer friends than the British.”
After that Trump and the King held private talks before the monarch made a speech to Congress.
This is the biggest diplomatic challenge of the King’s reign, writes our royal correspondent, and there are high stakes.
It also marks the first British state visit to the US since Queen Elizabeth II’s trip in 2007 – she was honoured with a 21-gun salute and a state banquet.–BBC
