Donald Trump is planning to invite King Charles to the United States.

The US President and First Lady Melania Trump departed the UK on Thursday (18.09.25) evening as his historic second state visit came to an end and a senior White House official has suggested that Trump wants to reciprocate the royal family's hospitality.

The official told The Daily Telegraph newspaper: "It was a really fantastic trip. The British know how to do this perfectly. They set the bar high for their trip to see us."

Before leaving on Air Force One, Trump thanked the monarch and his wife Queen Camilla as he hailed the bond between the UK and US.

The 79-year-old politician said: "We're grateful beyond words for the spectacular honour of the state visit yesterday at Windsor Castle, hosted by His Majesty King Charles III and Her Majesty, Queen Camilla.

"These are two fantastic people. We will never forget it."

Trump also gushed about the banquet held in St George's Hall at Windsor Castle on Wednesday (17.09.25).

The president told reporters: "Everybody was great. Even the men looked beautiful.

"It's hard not to look beautiful in that room. That was one of the coolest rooms. That room was built for a table, but the table happened to carry 200 people."

Trump had described receiving a second state visit to the UK - something not usually offered to US leaders during their second term in office - as "one of the highest honours" of his life.

Addressing King Charles directly, Trump said: "This is truly one of the highest honours of my life, I have such respect for you and such respect for your country for many decades."

Trump also praised the monarch's dedication to "preserving the glorious and unique character of this kingdom".

He added: "I just stood in line and shook about 150 hands, and the King knew every single person and every single company.

"Some of them had bad names like 'XYZ-Q3' and he knew every one of them, or at least I think he did, because nobody was complaining. I was very impressed with that."

The president also spoke of the UK's "special relationship" with the US.

He explained: "We're like two notes in one chord or two verses of the same prose.

"Each beautiful on its own, but really meant to be played together. The bond of kinship and identity between America and the United Kingdom is priceless and eternal. It's irreplaceable and unbreakable."
