It is not the first time the monarchy has been deployed in such circumstances. Last year, they were successfully tasked with using their soft power to help secure a favourable trade deal.
The UK has received some preferential treatment from the White House on tariff policy, and the trade deal has given Sir Keir something to highlight to his voters.
On Ukraine, the King sent for Volodymyr Zelensky after his bruising encounter in the White House, inviting him for tea and a show of support at Sandringham while Mr Trump cooled.
When Mr Trump appeared to be growing enthusiastic about the idea of invading Canada, and began testing the sovereign nation with escalating rhetoric about becoming the “51st state”, the King flew out for less than 24 hours to address the Canadian parliament as its King.
One senior diplomatic source likens the monarch’s role, historically, to helping put out small fires before they take hold.
King Charles, who is still having cancer treatment, will travel as and when the Government asks it of him, sources emphasise.
The Prince of Wales, too, will say yes if the Government makes a request. As yet, royal sources insist, there has been no official invitation for Kensington Palace.
If they do travel, it will be for events close to Independence Day, celebrated on July 4. The Prince, who is president of the Football Association and a fan of the sport, is likely to attend a World Cup match to support England while he is there.
The Princess’s attendance will depend on factors including her family’s schedule: the couple prioritise stability for their children and rarely travel overseas together for long without them.
All four senior members of the Royal family visiting America in one year would fulfil Trump’s desire for another “unprecedented” show of friendly force.
“His [positive] feelings about the Royal family trump – pun intended – his [negative] feelings about Starmer,” explains a source familiar with the US administration.
