US President Donald Trump is in Britain for a three-day state visit.
Accompanied by First Lady Melania Trump, the president arrived aboard Air Force One on Monday morning having already created a considerable degree of political turbulence with comments on the Tory leadership race, Brexit and the Duchess of Sussex.
On Tuesday, at a press conference with Prime Minister Theresa May, he revealed Labour leader Jeremy Corbyn had requested a meeting, but was rejected. It later emerged that the president held a 20-minute phone call with Tory leadership candidate Boris Johnson and met with Brexit party leader Nigel Farage, among others.
On Wednesday Mr Trump, and First Lady Melania, joined the Queen and Prince Charles, Mrs May and other world leaders, at a commemoration of the D-Day landings in Portsmouth with veterans.
The event was to tell the story of D-Day through musical performance, testimonial readings and military displays, including a fly-past of 25 modern and period aircraft.
The Queen was expected to bid a formal farewell to Mr and Mrs Trump before they travel to Ireland to meet Irish Prime Minister Leo Varadkar.

Donald Trump 'moved' by Prince Charles' passion on climate change
Donald Trump had a long conversation with Prince Charles about climate change on Tuesday, with the president saying he was 'moved' by the Prince of Wales' passion.
He told ITV: "We had a 15 minute chat and it lasted an hour and a half and he did most of the talking.
"What he really wants and what he feels strongly about is the future. He wants the best climate for the future.
"He wants a good climate and not a disaster."
Trump backtracks on NHS trade deal comments
The US President had used a joint appearance with Theresa May to say that the NHS would be "on the table" as part of a "phenomenal" potential transatalantic deal.
He said: "I think everything with a trade deal is on the table."
Theresa May replied: "But the point in making trade deals is of course that both sides negotiate and come to an agreement about what should or should not be in that trade deal for the future."
Soon after, Health Secretary and Tory leadership candidate Matt Hancock tweeted: "Dear Mr President. The NHS isn’t on the table in trade talks - and never will be. Not on my watch."
But in a U-turn he used a major TV interview to say "I don't see it being on the table" as the NHS was "something that I would not consider part of trade".
The President rowed back on his suggestion that access for US firms to the NHS must be part of talks for a post-Brexit trade deal.
Boris Johnson turns down face-to-face meet with US president
It emerged that Mr Johnson turned down a one-to-one meeting with Mr Trump just days after the US president appeared to endorse him as Mrs May's successor.
There were rumours the pair were going to hold private talks today in London, but instead it is understood they had a "friendly and productive" 20-minute phone call.
The reason the former Foreign Secretary turned down the private meeting is said to be because it would have clashed with One Nation leadership hustings.
Donald Trump seemed to throw his support behind the former Mayor of London as Britain's next Prime Minister, saying before the trip: "I think Boris would do a very good job. I think he would be excellent."
Corbyn's anti-Trump speech
Jeremy Corbyn turned down an invitation to the state banquet, where he would have had the opportunity to meet the US president.
On Tuesday, he took to a stage in Whitehall and addressed several thousands of protesters and said: "I am not, absolutely not, refusing to meet anybody. I want to be able to have that dialogue to bring about the better and more peaceful world that we all want to live in.
"But I'm very disappointed, particularly today, on the wonderful festival of Eid, that our Mayor of London Sadiq Khan has been attacked as he has.
"I am proud that our city has a Muslim mayor, that we can chase down Islamophobia, anti-Semitism, any form of racism within our society because racism divides."
Mr Corbyn added: "When you've created that sense of hate, when you've destroyed people's self esteem by those forms of racism, do you know what? You haven't built a house, you haven't built a school, you haven't trained a nurse, you haven't defended our natural world.
"All you've done is created a greater sense of hate and hatred that goes with it."
Donald Trump said, at the press conference held on Tuesday afternoon, a future UK-US trade deal had "tremendous potential", saying it could be "two or three times what we're doing at the moment".
Talking of Brexit, Mr Trump said: "I think it will happen. I believe the PM has brought it to a very good point where something will take place in the not too distant future."
There was a moment of humour at the end of their joint press conference when Mrs May was asked whether she should have taken the President's advice on Brexit.
Mrs May said: "It will be for whoever succeeds me to take this issue forward.
"I seem to remember the president suggest I sued the European Union, which we didn't do. We went into negotiations and came out with a good deal."
Mr Trump responded: "I would have sued and settled, maybe, but you never know.
"She's probably a better negotiator that I am.
"She has got it, in a sense - that deal is teed up, I think they have to do something.
"Perhaps you won't be given the credit you deserve if they do something, but I think you deserve a lot of credit - I really do."
In a surprising turn, Donald Trump said he refused to meet Labour leader Jeremy Corbyn, describing him as a "somewhat negative force".
He said: "I don't know Jeremy Corbyn. He wanted to meet today or tomorrow and I decided not to do that. He's somewhat of a negative force. People should look to do things decisively and not just criticise. I've decided not to meet him."
A Labour source later confirmed that the meeting had been requested, but that it was turned down.
Just as was the case during his last visit, a giant inflatable Donald Trump baby blimp is flying over London during the US president's state visit after its owners reached their fundraising target.
Organisers planned to fly the 20ft blimp above Parliament Square for two hours from 9am on Tuesday.
The blimp, which can be flown up to 100ft in the air, depicts the US president wearing a nappy and clutching a mobile phone.
A spokesman for the team behind the blimp said they had received permission to deploy the inflatable from the Greater London Authority, headed by London Mayor Sadiq Khan, and the Civil Aviation Authority.
This year, the Trump Baby team, which is part of the Stop Trump coalition, said the blimp would only be flown if a crowdfunding target of £30,000 was met to support groups focused on tackling social issues.
Organisers announced the target was reached on Sunday and raised it to £50,000 to give the groups an "even bigger boost".
President Trump was asked about the protests in the press conference with Theresa May and he said: "I did not see the protesters until just a little while ago and it was a small group of people put in for political reasons."
The Royal reception at Buckingham Palace
The Queen welcomed US President Donald Trump to Britain as they shared a warm handshake at Buckingham Palace on the first day of the three-day state visit.
Mr Trump and the First Lady Melania were greeted by Prince Charles and the Duchess of Cornwall after their helicopter, Marine One, landed on the West Lawn of the palace just before 12.15pm.
President Trump climbed up the stairs and shook hands with The Queen, who smiled broadly before turning to greet the First Lady.
At the invitation of Her Majesty The Queen, troops from the British Army’s Household Division delivered an immaculate Guard of Honour for the arrival of the President, who was invited to inspect the guard of honour.
In an unusual move, the president took the time to talk to each soldier individually.
Charles accompanied the president as he strode onto the lawns to inspect the waiting troops formed up in two lines with the guardsmen wearing their famous scarlet tunics and bearskins.
Several of the guardsmen on parade have US links and all will at some point in their careers train alongside US forces.
As the President arrived on the West Lawns, two 41-gun salutes fired simultaneously in The Green Park by the King’s Troop Royal Horse Artillery and at HM Tower of London by the Honourable Artillery Company.
The Trumps and the royals then went inside the palace, through the Bow Room, where the Queen introduced senior members of her household to her guests and in-turn the US leader did the same with prominent figures from his entourage.
They then sat down to lunch.
Afterwards, the First Couple went to Westminster Abbey, and then in the evening, attended the state banquet.
The Trump-Khan tit-for-tat
Donald Trump's state visit to the UK was never going to be a quiet affair, and he made doubly sure by launching a social media grenade before he had even landed on British soil.
Tweeting while still in the air over Stansted Airport, he called Mr Khan a "stone cold loser", saying he had done a "terrible job" after the mayor on Sunday described the president as "just one of the most egregious examples of a growing global threat" and compared the language he has used to that of the "fascists of the 20th century".
Clearly still smouldering, Mr Trump continued to rant to Foreign Secretary Jeremy Hunt, who was at the Essex airport to greet him.
Mr Hunt said: "He shared his strong feelings about the Mayor of London," when asked what they talked about. Although the Tory leadership hopeful would not divulge the exact details of what was said, he said it was consistent with the language he used in his tweets about Mr Khan.
The Foreign Secretary continued: "The president does what the president does but let's ask why he was so angry when he did that tweet and I think the very simple reason is he's been shown great discourtesy.
"What I would say is for Sadiq Khan and the Labour Party to be boycotting the state visit of the President of the United States, who has been invited here not by Theresa May but by Her Majesty the Queen to celebrate a relationship that goes back centuries but just 75 years ago saw a million American servicemen on our soil land ready to make the ultimate sacrifice for our liberty, is I'm afraid, virtue-signalling of the worst kind."
In response to the tweets, a spokesman for Sadiq Khan said: "This is much more serious than childish insults which should be beneath the President of the United States.
"Sadiq is representing the progressive values of London and our country, warning that Donald Trump is the most egregious example of a growing far-right threat around the globe, which is putting at risk the basic values that have defined our liberal democracies for more than 70 years."
