But the previous visit sparked a public relations storm over the president’s behaviour during the ceremonies, including whether he walked ahead of the Queen and turned his back on her.
Trump was reproached in parts of the British media for this slip in royal etiquette, as well as for arriving 15 minutes late to the formal greeting from the Queen, who was said to dislike tardiness.

The September visit will require delicate diplomacy after the King flew to Canada in May to open parliament at a time of strong criticism of Trump for his repeated claims that Canada should become the 51st state of the US.
Canadian Prime Minister Mark Carney, who was engaged in public rows with Trump over trade, oversaw a speech for the monarch that emphasised sovereignty and independence.
Reading the speech prepared by the government, King Charles told parliament: “The True North is indeed strong and free.”
Trump joined Carney at the G7 summit in Canada last month but left the event early and has since threatened the country with tariffs of 35 per cent, slightly worse than the 30 per cent rates proposed for the European Union and Mexico.

Starmer, however, sealed a trade agreement with Trump at the G7 summit that avoided steep tariffs on British goods.
There have been tensions in the relationship, however, on the key question of Ukraine after Trump withdrew support from the country and Starmer took a starkly different approach, scaling up help instead.
King Charles hosted a banquet for Macron last week with guests including Sir Elton John, Sir Mick Jagger, Dame Kristin Scott Thomas, author Sebastian Faulks and footballer Mary Earps.
While Macron addressed both houses of the UK parliament last week, Trump did not do so in his 2018 visit and may not be able to do so in September because of the Westminster schedule.
The House of Commons will be in recess at the time of the visit, although the House of Lords will be sitting.
Trump will also visit the UK later this month for an informal trip to his new golf course in Aberdeenshire in Scotland, but this is not expected to include any time with the King.
