They also were late when meeting Queen Elizabeth, causing her to check her watch, on camera, several times. With the queen in the middle, the Trumps seemed to tower over the monarch, who stands roughly 5-foot-3.
"If they're going somewhere or having a walk around, the Queen will actually walk slightly in front or alongside Mr Trump", Harrold said ahead of Trump's meeting.
Instead of holding his meetings in London, Trump will instead hold talks with Prime Minister Theresa May at her country retreat outside the city and take tea with the Queen at Windsor Castle, west of London.

The queen was forced to bob and weave as she caught up to walk alongside him.
"The Star-Spangled Banner" was then played and the Queen guided the president on a review of the honour guard in the castle courtyard. Trump and First Lady Melania Trump met Britain's longest-serving monarch at Windsor Castle as part of a four-day tour.
While Trump typically likes to take the lead, he appeared to follow the queen's direction, adjusting his pace to hers.
The Trumps and the queen were scheduled to spend about 30 minutes getting acquainted over tea inside the castle but the visit stretched past 45 minutes.

"No one really wants him to be in power ... he's not welcome in the United Kingdom, said Holly, a protester from London, who didn't give her last name". Perhaps so. But what you see in the photo is Parliament Square. "She is just an incredible woman".
"My mother loved the queen".
However, they do add: "But many people wish to observe the traditional forms". HRH has met with every sitting president since ascending to the throne in 1952, with the exception of Lyndon Johnson.
