The US President, along with First Lady Melania Trump, was originally due to arrive on Wednesday, September 17, as the guests of King Charles and Queen Consort Camilla.
However, they will now arrive in the UK to stay at Windsor Castle on the evening of Tuesday, September 16, and leave on Thursday, September 18, after their programme at Chequers finishes.
Trump’s stay with the King and Queen will have no public-facing element on the first day of his state visit, when he will remain within the private Windsor estate, Buckingham Palace has confirmed.
The palace has released the itinerary of the American politician’s two-day stay, which begins in full on Wednesday, September 17.
Mr Trump will be treated to a flypast by the Red Arrows and UK and US F-35 military jets on the East Lawn at Windsor Castle and a special Beating Retreat military ceremony.
The series of special additions – believed to have never been deployed before at an incoming state visit – will be staged in the US president’s honour on Wednesday, alongside the traditional grand state banquet and ceremonial welcome.
The Prince and Princess of Wales have been tasked with the initial meeting of Mr and Mrs Trump on the morning of September 17 in the grounds of the Windsor estate, and will accompany them to meet the King and Queen for an open-air greeting.
The Trumps, the King, Camilla, William, and Kate will then take part in a carriage procession through the estate to the castle.
The route will be lined by members of the armed forces, with three military bands from the Royal Marines, the Army, and the RAF.
A ceremonial welcome with a guard of honour will be staged in the quadrangle of the castle, followed by lunch with the royal family, and a visit to see a Royal Collection exhibition within the castle.
The President and his wife will visit St George’s Chapel privately on Wednesday afternoon to lay a wreath on the tomb of Queen Elizabeth II, and then be given a short tour of the chapel and hear a musical performance from the chapel choir.
On Thursday, the President and First Lady will formally bid farewell to the King and Queen at Windsor Castle in the morning.
Mr Trump will head to Chequers, the Prime Minister’s official country residence in Buckinghamshire, where he will be met by Sir Keir and Lady Starmer and greeted with a Guard of Honour from RAF Halton and bagpipers.
The President and the Prime Minister will view the Sir Winston Churchill archives held at Chequers, before having a bilateral meeting, joining a business reception with the Chancellor, and then holding a press conference.
Meanwhile, the First Lady will carry out engagements with the Queen and Princess of Wales at Windsor.
She will first spend time with Camilla, touring Queen Mary’s Dolls’ House and the Royal Library.
Then, Mrs Trump will join Kate at Frogmore Gardens where they will meet Chief Scout Dwayne Fields and members of the Scouts’ Squirrels programme as they learn about nature to achieve their Go Wild badge.
The First Lady will then travel to Chequers to join Mr Trump for the remainder of the final day’s programme.
