Sky News reported Wednesday that plans have not been formalized, but Trump will likely meet with the monarch on July 13 at Windsor Castle.

"Yes, I mean he has to see the head of state. Putting his foot on British soil, it's job one, it's very important, very symbolic," Johnson told the news outlet when asked if Trump would see the queen.

"Meeting Her Majesty is the most important thing, because she's the head of state, and from then on, it'll be what the president wants to do,” Johnson added.

The queen once compared Trump to a noisy helicopter, joking earlier this year that he goes “round and round when you want to talk.”

Trump is traveling to the U.K. for a “working visit” with Prime Minister Theresa May, the White House announced in April.

May was the first foreign leader to visit Trump after his inauguration last year.

The two leaders have recently clashed, however, over what May called “unjustified and deeply disappointing” tariffs on steel and aluminum imports.

The prime minister on Wednesday also condemned Trump’s policy of separating migrant families at the U.S.-Mexico border.

"This is wrong, this is not something that we agree with. This is not the U.K.'s approach," May said.
