Guests have arrived at Buckingham Palace for a State Banquet alongside President Trump.
The banquet is being held in the Ballroom at Buckingham Palace and will see President Trump and the First Lady sat with members of The Royal Family and around 170 other guests.
The Queen, the Prince of Wales, the Duchess of Cornwall, the Duke & Duchess of Cambridge, and the Duke of Sussex are among some of the royals expected to attend.
Theresa May will also attend the dinner – one of her last engagements as Prime Minister.
Labour leader Jeremy Corbyn, House of Commons Speaker John Bercow and Liberal Democrat leader Sir Vince Cable are boycotting the event.
President Trump and the First Lady will be seated at the top of the U-shaped table alongside The Queen, the Prince of Wales and the Duchess of Cornwall.
President Trump and The Queen will then each deliver a speech followed by the playing of national anthems.
