Donald Trump calls Meghan Markle 'nasty', supports Boris Johnson

Ahead of his visit to the United Kingdom next week, United States President Donald Trump has opened up about the Duchess of Sussex, Meghan Markle.

Trump will meet with several figures from the royal family while visiting England from June 3, including Queen Elizabeth, Prince Charles, Prince Harry, and Prince William.

But new mum Meghan Markle won't be heading along to meeting the man she once called "misogynistic" and "divisive" as she recovers from the birth of baby Archie and spends time with him.

That might be for the best. In an exclusive interview with The Sun, the US President was asked what he thought about her comments about him.

Trump said he hadn't heard the comments.

"What can I say? I didn’t know that she was nasty."

He did however admit that it's nice to have an "American princess" and is sure she will do "excellently" in the role.

"She will be very good. I hope she does [succeed]."

Trump's visit comes at a difficult time for the United Kingdom, with Prime Minister Theresa May set to step down as leader on June 7. Trump said he respects May but doesn't believe she has dealt with Brexit correctly.

He expressed his support for Boris Johnson, saying he would do excellent if he was to take over as Prime Minister, and said he may meet with him during his visit.
