US President Joe Biden is due to travel to the UK to meet King Charles and Prime Minister Rishi Sunak later this month.
It is the first time the US president has met the king since the coronation in May.
Mr Biden’s diplomatic trip abroad – during which he will also visit Lithuania and Finland – will take place from July 9-13.
Buckingham Palace has confirmed that King Charles is due to meet the President at Windsor Castle on Monday July 10.
Mr Biden did not attend the king’s coronation in May – but his wife, first lady Jill Biden, and granddaughter went instead.
His visit follows Sunak’s two-day trip to Washington in June, where the two leaders discussed Ukraine, a post-Brexit economy and the pros and cons of artificial intelligence.
This month’s meeting would “further strengthen the close relationship between our nations,” the White House said.
Downing Street issued a similar statement, saying Mr Biden’s upcoming visit “reflects the strong relationship” between the UK and the US.
“The Prime Minister looks forward to welcoming President Biden to the UK later this month,” a Number 10 spokesperson said.
“It reflects the strong relationship between the UK and the US, building on a series of visits and bilateral meetings earlier this year.
“We will give more details in due course.”
Earlier this year, Mr Biden stopped in Belfast to mark the 25th anniversary of the Good Friday Agreement and briefly met Mr Sunak.
After the United Kingdom, the American president will travel to Vilnius in Lithuania for the NATO summit, which will take place on July 11 and 12.
On his last day, he will travel to Helsinki, Finland, for a summit of US-Nordic leaders, where talks are expected to focus on the Russian-Ukrainian war.
