Trump’s royal greeting: What happened?
Sky News US correspondent Mark Stone said the positioning of each guest around the table is also telling.
He said across from Mr Trump and the King, on the other side of the table, was the Queen, the first lady, the Prince of Wales and Treasury Secretary Scott Bessent, which, Stone said “gives you a hint of how much this is all about business”.
Among the guests of honour were, of course, Donald and Melania Trump, alongside King Charles, Queen Camilla and Prime Minister Sir Keir Starmer.
The Prince and Princess of Wales were in attendance, as were the Duke and Duchess of Gloucester, the Princess Royal and her husband, Vice Admiral Sir Tim Laurence.
