President Donald Trump is wading into the United Kingdom's political maelstrom days before he is set to embark on his first state visit there, saying Boris Johnson would make an "excellent" prime minister and calling Meghan, the Duchess of Sussex, "nasty."

In an interview on Friday with the British tabloid The Sun, Trump expressed support for the controversial ex-foreign secretary in his bid to replace Theresa May, saying, "I think Boris would do a very good job. I think he would be excellent."

May is to step down amid an impasse over Brexit on June 7, just days after Trump is set to be feted by Queen Elizabeth II at Buckingham Palace and after official observances of the 75th anniversary of D-Day are concluded.

Trump referred to the American-born as "nasty" over comments she made in 2016 threatening to move to Canada if Trump won the White House.

"I didn't know that she was nasty," he said of Meghan when read her prior criticism. The former Meghan Markle married Prince Harry, the Duke of Sussex, in 2018 and gave birth to their first child, Archie, in May.

During the state visit, the president, his wife, Melania, and his four adult children are expected to meet with Harry as well as his brother, Prince William, the Duke of Cambridge, and his wife, Kate, the Duchess of Cambridge. Meghan is expected to stay home with Archie.

Trump told the newspaper that he didn't know that he wouldn't be meeting Markle but predicted that she will make "a very good" American princess.

As for May, Trump criticized her handling of Brexit negotiations with the European Union, saying she "didn't give the European Union anything to lose." Trump's first visit to the UK as president was marred by similar critical comments he made to the same tabloid last year about May's handling of Brexit.

Trump is scheduled to arrive in London on Monday for a three-day visit.
