US President Donald Trump and First Lady Melania Trump are making a state visit to the UK from 3 to 5 June.
Going by tradition, the Queen usually receives one or two heads of state per year and has hosted a total of 112 of such visits since becoming monarch in 1952.
The Queen’s vsitors usually stay at either Buckingham Palace or Windsor Castle, but because Buckingham Palace is being renovated the US president is not expected to stay there.
On Monday, the first day of Mr Trump’s three-day trip, a ceremonial welcome attended by the Queen, Prince of Wales and Duchess of Cornwall was held in the Buckingham Palace garden.
After the welcome, the Duke of Sussex joined the group for a private lunch at the palace.
Mr and Mrs Trump then visited Westminster Abbey for a tour and met Prince Charles and the Duchess of Cornwall for tea at Clarence House.
A state banquet in the palace’s ballroom took place on Monday evening, with Mr Trump, the Queen, Prince Charles and the Duchess of Cornwall joined by the Duke and Duchess of Cambridge, along with other UK public figures and prominent Americans living in Britain.
On Tuesday, Mr Trump and Prime Minister Theresa May will host a business breakfast attended by the Duke of York at St James’s Palace.
In the evening, the Trumps will host a dinner at the residence of the US ambassador attended by Charles and Camilla on behalf of the Queen.
The trip is expected to culminate on Wednesday 5 June with Mr Trump, the Queen and Prince Charles attending the national commemorative event in Portsmouth for the 75th anniversary of the D-Day landings.
More than 300 veterans will be at the ceremony, which will feature musical performances, testimonial readings and military displays.
Labour leader Jeremy Corbyn refused to attend Mr Trump’s state banquet, accusing the president of using “racist and misogynist rhetoric”, while Liberal Democrat leader Sir Vince Cable also declined an invitation.
