What to know about President Trump’s second state visit to the UK

London: President Donald Trump and his wife, Melania, are set to arrive in Britain on Tuesday night for a two-day state visit, hosted by King Charles and Queen Camilla.

In Britain, state visits are hosted by the monarch, and are a moment when the country rolls out the red carpet for visiting foreign royalty, presidents or prime ministers, showcasing the pomp, pageantry and ceremony for which the country is known.

Designed to strengthen Britain’s ties with other nations, the program usually includes a glittering banquet in a royal palace and a procession in a horse-drawn carriage.

State visits are arranged at the invitation of the sovereign, acting on government advice. They do not take place between Britain and the 14 countries, including Australia and Canada, that are members of the Commonwealth and share the king as head of state.

Mr. Trump and the first lady can expect all the finery and flourishes of a stay with the royal family. The carriage procession through the Windsor estate will be escorted by mounted soldiers from the Household Cavalry. At a white-tie state banquet on Wednesday evening, attended by around 150 guests, the king will make a speech and propose a toast to the president, who will reply and propose a toast in return.

Typically, one or two take place each year, with King Charles III undertaking a similar number to other countries.

Queen Elizabeth II hosted around 112 state visits in Britain between her accession in 1952 and her death in 2022 and made 89 outbound state visits between 1955 and 2015.

The most recent foreign leader to receive the honor in Britain was President Emmanuel Macron of France in July.

Wasn’t President Trump in Britain recently? And has he made a state visit before? Yes, and yes. In July, Mr. Trump, whose mother was born in Scotland, opened a new golf course in Aberdeenshire. While the trip was officially a vacation, the president held talks with Ursula von der Leyen, the president of the European Commission, and with Prime Minister Keir Starmer of Britain.

In 2019, during his first presidency, Mr. Trump was hosted for a state visit by Queen Elizabeth II. A second state visit is an unusual honor. At the White House in February, Mr. Starmer handed the president a letter from King Charles inviting Mr. Trump to return.

On Thursday, the president will travel to Chequers, the official country residence of the British prime minister, where he will be greeted by Mr. Starmer and his wife, Victoria. The two leaders are likely to address a news conference in the afternoon. Before that they are expected to visit the Winston Churchill archives at Chequers and join a business reception.

Mrs. Trump will remain at Windsor, where she will see Queen Mary’s Dolls’ House with Queen Camilla, and later join Catherine, Princess of Wales, at Frogmore Gardens for an event with Britain’s Scouts Association.
