President Donald Trump and First Lady Melania Trump took a carriage ride around the grounds of Windsor Castle in England while visiting King Charles III.

Thousands of protesters took to the streets of London on Wednesday to rally against the second state visit of Trump.

The U.K.'s largest military ceremony for a visiting foreign leader in living memory brought out the full weight of Britain’s ceremonial traditions to welcome the American president.

It's been nearly four decades since King Charles III traveled to Palm Beach to sip cocktails with socialites at Trump's Palm Beach estate.

Earlier on Tuesday, dozens of protesters gathered outside Windsor Castle as part of a demonstration organized by the Stop Trump Coalition. Attendees could be seen holding flags and banners, one of which read: “Go away. You are polluting Windsor.”

Donald Trump previously exchanged barbs with Sir Sadiq Khan on Twitter, accusing the London mayor of doing a "terrible job" with the city and that he was a "nasty person"
