The visit's itinerary includes an initial meeting with Prince William and Princess Kate at Windsor estate, a carriage procession to the castle, a state banquet at St George’s Hall, and a day at Chequers with the prime minister.
The Princess of Wales will accompany Melania Trump for a day at Frogmore Gardens to meet Chief Scout Dwayne Fields and members of the Squirrels programme.
The previous state visit by Mr Trump in 2019 incurred costs of around £3.9 million, mainly for policing, which would be over £5 million in today's money.
