Forget bilateral meetings and photo ops at Downing Street: When it comes to navigating an uncommonly turbulent era in the Special Relationship, the U.K. government’s most powerful diplomatic tool may be sparkly and worn on somebody’s head.
We refer, of course, to the epic demonstration of “tiara diplomacy” — that is, wheeling out the royals in full Beribboned and Bejewelled mode — the world is about to be treated to as Britain welcomes Donald Trump for his second state visit to the island nation.
Technically, it was the King who signed the invitation (although, as with all state visits, it’s at the behest of the government, not the royals’ whim), which was hand-delivered by U.K. Prime Minister Keir Starmer when he met with the U.S. president in Washington earlier this year. Trump said yes on the spot.
This means the Royal Family will be front-and-centre when it comes to hosting duties, flexing all the soft power at their disposal (and, perhaps, reminding the British public why they’re worth keeping on.)
Here’s everything you need to know about how the royals are rolling out the red carpet for Trump this week.
1. Trump has had a long fascination with the Royal Family
Like Teresa May before him, who invited Trump for his first state visit within days of starting his first term, Keir Starmer knows that the U.S. president is a big royal fan. “She is so sharp, so wise, so beautiful,” Trump said to Piers Morgan of the late queen in 2018. (He was similarly complimentary about Prince William, saying after he met him at the reopening of Notre Dame last year that “he’s a good-looking guy.”)
As he heads to the United Kingdom, Donald Trump calls King Charles III, Queen Camilla “friends of mine for a long time.” Trump called the king an “elegant gentleman” and said, "he represents the country so well.” (Sept. 16, 2025)

She lit up the room with her charm, her presence. She was a genuine princess — a dream lady.” His 2019 state visit — the last Queen Elizabeth II ever hosted — seems to have been one of the highlights of his first term, although according to biographer Craig Brown the late queen actually found him “very rude.”
Another sign of his reverence for the queen? Trump will be placing a wreath on her tomb in St. George’s Chapel during this visit.

The Prince and Princess of Wales have been tapped to greet Donald and Melania Trump when they arrive in Windsor on Wednesday morning. It’s a move that’s being interpreted as a sign of the couple’s steadily growing importance within the family.
According to the president, when they met privately after the Notre Dame event, he and William had a “great” conversation, while Kate was also present at the banquet held for the last state dinner, too.
After this welcome, the Prince and Princess will take the Trumps to see King Charles and Queen Camilla, and thenceforward on to a carriage procession followed by military procession.

Putting the actual tiara in Tiara Diplomacy, the public centrepiece of this visit will be the state banquet on Wednesday evening. Always an occasion when the royals dial the pomp and circumstance up to 11, it’s also a chance for them to raid the family jewel box and, if they’re a woman, wear a tiara. While there’s a chance she may surprise us, it’s very likely that Kate will wear her favourite (and a Diana go-to as well), the Cambridge Lover’s Knot Tiara. Queen Camilla is more of a wild card, although a nice nod to the late queen would be to wear the same tiara, the Burmese Ruby Tiara, that Elizabeth wore to the last U.S. state banquet in 2019.

In one of the more interesting items on the itinerary, the Princess of Wales and the first lady will be spending official time together on Thursday. On the grounds of Windsor Castle, they’re hosting an event for The Scouts that celebrates time spent in nature, something Kate has become a big advocate for. Earlier in the day, Queen Camilla is going to give Melania a tour of the library at Windsor Castle, plus a look at the famous Queen Mary’s Doll House.
