Ahead of his meeting with Queen Elizabeth II at Windsor Castle this afternoon, protestors swamped Oxford Street bearing signs emblazoned with apt messages such as: "Feed him to the corgis".
There were handshakes all around, and then the threesome stood side-by-side as a military band played the American national anthem.
Mr Trump also displayed hand movements of "suppressed dominance" as he tried to steer the Queen.

US President Donald Trump was invited to inspect the Coldstream Guards at Windsor Castle, accompanied by Her Majesty the Queen.
The first lady wore a pale pink two-piece ensemble with her hair pulled back for the occasion; the queen was in a blue coat.
We may never know if Trump was actually late, or if the queen has a habit of checking her watch, but we should point out that it's interesting how no other members of the royal family appeared at the visit with the United States president.
While Trump typically likes to take the lead, he appeared to follow the queen's direction, adjusting his pace to hers.
Trump said May could not now walk away from negotiations with Brussels "because if she walks away she's stuck".

"Great progress being made", Trump tweeted on Thursday along with the letter, calling it a "very nice note from Chairman Kim". Trump himself has remained upbeat about the outcome of the first summit between the leaders of the USA and North Korea.
Queen Elizabeth's tea for the Trumps was due to last 25 minutes according to the White House's schedule, the last part of their official visit.
"Whatever anybody thinks of President Trump, America is our closest and most important ally in the world".
"He did literally eclipse her, but I don't think that was deliberate".
"You could see that suppressed dominance where he felt that he had to still motion to her. She is just an incredible woman", Trump told The Sun newspaper.
He also talked about how his mother, who was born in Scotland, loved the royal family and all things pomp and pageantry. HRH has met with every sitting president since ascending to the throne in 1952, with the exception of Lyndon Johnson.
