British royal pageantry, guards of honour and castles will be front and centre as the UK prepares to put on a show for US President Donald Trump this week.
Mr Trump and his wife Melania will arrive in the UK for a three-day visit on Tuesday.
Such a visit is unprecedented, in that it will be the first time a US president has had two state visits to the UK while in office. His first state visit was during his first term.
Here's how events are expected to unfold, and what topics could loom large over the US president's stay.
Pomp and pageantry
Mr and Mrs Trump will arrive in the UK on Tuesday night to be welcomed by the king's representative.
Their first stop on Wednesday will then be Windsor Castle, joining King Charles, Queen Camilla, Prince William and Princess Kate for a carriage procession through the estate.
There will also be a state banquet on Wednesday night, where both the king and the president will deliver speeches.
A delegation of top US officials will accompany the Trumps, including Secretary of State Marco Rubio, Treasury Secretary Scott Bessent, and the White House's envoy to Ukraine and the Middle East, Steve Witkoff.
On Thursday, Mr and Mrs Trump will visit Chequers — the prime minister's residence outside of London — where he will hold a press conference with British Prime Minister Keir Starmer.
From there, the president and first lady will return to Washington DC.
A 'world-leading' tech partnership
While visiting Chequers, Mr Starmer will be hoping Mr Trump will help write some cheques to help the ailing UK economy.
US media is reporting that the two leaders will sign more than $US10 billion ($15 billion) worth of deals in technology and nuclear projects.
Even before Mr Trump's arrival, the UK government announced over 1.25 billion pounds ($2.5 billion) of US investment from PayPal, Bank of America and others.
A spokesperson for the prime minister said the leaders would sign "a world-leading tech partnership" during the president's visit.
"The UK-US relationship is the strongest in the world," the spokesperson told reporters.
"This week we are delivering a step change in that relationship."
British economic growth has been anaemic in recent years, with voter frustration rising at the UK Labor government after only a year in office.
With that in mind, ministers are hoping those big spending agreements could help spark growth.
Trade talk
Despite Mr Starmer and Mr Trump hailing from opposite sides of the political divide, they have forged an unlikely working relationship.
That has worked out to the UK's advantage in dealing with Mr Trump's efforts to up-end global trade.
This year, the UK and US announced an economic deal that saw Britain fare better than many of America's other close trading partners.
It is expected this visit will see more details of that deal finalised, including on tariffs on imports of cars, aluminium and steel.
"When it comes to steel, we will make sure that we have an announcement as soon as possible," British Business Minister Peter Kyle told the BBC on Sunday.
Defence cooperation will also be a key pillar of the trade agreement, a White House official said.
This could have implications for the AUKUS security pact between Australia, the UK and the US, which is currently being reviewed by the Pentagon.
A nuclear power pact
The two countries are set to sign a deal to work together on nuclear energy projects, as Mr Starmer promises a new "golden age of nuclear that will drive down household bills".
The deal is also part of a broader American push to encourage its allies to increase nuclear power generation, while reducing reliance on Russian nuclear fuel.
"As a matter of policy, we are encouraging our friends and allies to develop more nuclear energy," a US official said.
"We think that's critically important – really, the only way forward of getting us out of some of the energy traps they find themselves in."
American and British energy companies are expected to announce plans to build up to 12 advanced modular reactors in northern England.
Heavy security presence
Meanwhile, British police are gearing up for "just about every foreseeable eventuality".
"This is a significant policing and security operation, as would be expected for a state visit of the president of the United States," Thames Valley Police Assistant Chief Constable Christian Bunt says.
Mr Trump will be confined mainly to the private grounds of Windsor and Chequers, and will not travel to London.
The heightened security presence comes only days after right-wing activist Charlie Kirk was shot dead at a Utah event.
Questions around Epstein
Mr Trump's arrival in the UK comes just days after the lingering questions about deceased paedophile Jeffrey Epstein crossed the Atlantic yet again.
The US president has been under pressure from many of his most loyal supporters over his alleged links to the disgraced financier, who died in his Manhattan prison cell in 2019.
But it was revelations last week about Peter Mandelson, the UK ambassador to the US, that caused serious damage to Mr Starmer's Labour government.
The UK prime minister decided to sack Lord Mandelson over his ties with the late convicted US sex offender.
