President Barack Obama is to travel to Britain next month, the White House has confirmed.
The US leader will have a private dinner with the Queen at Windsor Castle and stage a joint conference with David Cameron at 10 Downing Street.
It is likely to be the president's last visit to the UK before his term in office ends in January.
A White House spokesman said: "The visit will allow the president to offer his gratitude to the British government and people for their stalwart partnership with his administration and the American people throughout his presidency."
