Longtime London Mayor Sadiq Khan quickly returned fire on Donald Trump after the American President attacked him as “nasty” while speaking with UK Prime Minister Keir Starmer.

“I’m not a fan of your mayor,” Trump told reporters in Scotland at his golf course during a lengthy sit-down with Starmer. “I think he’s done a terrible job, the mayor of London, but, uh, nasty person.”

“He’s a friend of mine, actually,” the Prime Minister interjected with a laugh.

“No, I think he’s done a terrible job, but, uh, but I would certainly visit London,” Trump added.

The President will be heading to the UK in September for a rare second state visit. He previously called Khan a “stone cold loser,” BBC News reported.

Trump also dangled an interest in addressing Parliament, while lamenting that it is in recess.

In response to the President’s “nasty” comment, a spokesperson for the London Mayor responded, according to The Guardian’s political editor.

“Sadiq is delighted that President Trump wants to come to the greatest city in the world,” the statement read. “He’d see how our diversity makes us stronger not weaker; richer, not poorer.”

“Perhaps these are the reasons why a record number of Americans have applied for British citizenship under his Presidency,” the spokesperson added.
