Donald Trump will meet the Queen at Windsor Castle on his four day trip and first official visit to the UK.
The president will not, however, be honoured with a state visit, which would include an official banquet at Buckingham Palace or a carriage procession up the Mall.
Mr Trump will be kept well outside London for the bulk of his first visit to the UK as US President, avoiding protesters who are expected to gather in the capital.
It is one of the most significant visits to the UK by a foreign statesman in a generation, with every available detail on Donald Trump’s brief stay coming under the microscope.
Here's what we know about Donald Trump's visit so far:
- When is the president due to arrive?
The president's arrival is shrouded in secrecy for security reasons, but we do know that he will be coming via the Nato summit in Brussels.
He is expected to be in London in time for his first engagement of the day on Thursday July 12.
His first stop will be a black-tie dinner at the Grade I-listed Blenheim Palace in Oxfordshire, hosted by Theresa May.
Blenheim Palace is an important visit for the President - it was the birthplace of Winston Churchill, a bust of whom was restored to the Oval Office by Mr Trump on his first few days in post.
It had previously been removed by predecessor Barack Obama.
Churchill also proposed to Clementine Hozier at Blenheim.
The president and his wife Melania will be guests of honour at a dinner for around 100 guests in the spectacular setting in Oxfordshire.
Downing Street said other guests will include leaders from business sectors including representatives from financial services, the travel industry, creative industries, the food and drink sector, engineering, tech, infrastructure, pharmaceuticals and defence - celebrating the business links between the UK and US.
- What will happen?
If previous engagements between President Trump and other heads of state are anything to go by, a lot of handshaking.
The evening will begin with a military ceremony in the three-acre Great Court of the palace performed by the bands of the Scots, Irish and Welsh Guards.
There will be much for the president to feel patriotic about on foreign soil, particularly when the bands perform the Liberty Fanfare – devised by ET and Star Wars composer John Williams to mark the re-dedication of the Statue of Liberty – the instantly recognisable National Emblem military standard composed at the turn of the 20th century by Edwin Eugene Bagley, and the popular if slightly funereal hymn Amazing Grace.
During dinner, the Countess of Wessex’s string orchestra military band will perform a series of classic British and American hits, although no further detail has been provided as to which songs will feature.
The Royal Regiment of Scotland will pipe the president out at the end.
They will then stay at Winfield House, the US Ambassador’s residence in London.
- When will the president meet the Queen?
President Trump will meet Queen Elizabeth II after lunch on the Friday at Windsor Castle.
The president has not been honoured with a state visit - the trappings of which would involve a banquet at the monarch's London residence Buckingham Palace, or a carriage procession up the Mall.
- Why is the president not staying at the US Embassy?
The President rather nailed his colours to the mast earlier this year when he criticised a decision to move the building from Grosvenor Square to Nine Elms, Battersea, in south London.
He told a rally in Michigan: “In the UK, in London, we had the best site in all of London. The best site.
"Well, some genius said, we’re gonna sell the site and then we’re going to take the money and build a new embassy.
"That sounds good right, but you’ve got to have money left over if you do that, right?
"They go out and they buy a horrible location. And they build a new embassy.
"That’s the good news. The bad news is it cost over a billion dollars.”
- What does his second day in the UK have in store?
Mrs May and President Trump will reunite on Friday morning for a demonstation of the UK’s military muscle.
Downing Street has said more details will be revealed at a later date.
They will then travel to Chequers, arena for the Prime Minister’s lengthy Cabinet showdown on Friday, for what is being billed as “substantive bilateral talks on a range of foreign policy issues”.
This could include trade tariffs, Russia and North Korea.
- Will we find out what is discussed?
A press conference is pencilled in for this section of the itinery, although it is likely to be decided nearer the time who – if anyone – faces the cameras.
- When does Mr Trump leave?
On Friday evening he will head to Scotland, somewhere he once described it as “the great nation of my ancestors”, where he owns two golf courses.
It is indeed possible the president will decide to play either Trump Turnberry or the Trump International Golf Links in Aberdeen.
He may also visit the Isle of Lewis where his mother, the late Mary MacLeod Trump, was born before emigrating to the US in the 1930s.
President Trump and the First Lady are expected to depart for Europe on the Sunday.
- What about the Trump Baby blimp and any protests?
The crowdfunded inflatable depicting the president in a nappy has not been mentioned in the official itinerary.
With so few public appearances earmarked, it seems unlikely that the president will come close enough to Westminster or be outside long enough to see the “Trump baby” blimp or any protesters.
Protesters plan to fly the blimp over the Houses of Parliament after receiving permission for the stunt from London Mayor Sadiq Khan.
When asked whether the President’s schedule was designed to keep him away from possible protests, a Downing Street spokeswoman said: “Prime ministers frequently make use of Chequers for meetings with foreign leaders.
"It offers a more informal setting for important bilateral discussions.”
Previous presidents Richard Nixon, George Bush Senior and George Bush Junior have all visited the 16th-century country Buckinghamshire manor house for meetings with former PMs.
“We’re looking forward to making sure the president has a chance to see and experience the UK beyond London and the South-East,” said the Number 10 spokeswoman.
She added: “As with any protest, we are a free and open democracy and we believe in the right to peaceful protest. But I would also say that I think the majority of British people understand the importance of the UK-US alliance.
“The presidential visit is an important moment to recognise our close and special relationship and to have good and frank discussions on the key issues.”
