Sadiq Khan has claimed Donald Trump is “obsessed” with him after the US President heavily criticised him once again in a new interview. The London Mayor hit back after the US President branded him “a horrible mayor” in the latest in a long line of attacks.

Speaking to POLITICO on Tuesday, the former Labour MP urged Mr Trump to explain his insinuation that migrants “coming in” to Britain were responsible for Sir Sadiq’s electoral successes. He said: “I think it’s for President Trump to explain what he means by that. I’m unclear.”

He emphasised London’s appeal, noting record numbers of Americans are “flocking” to the city to live, invest, study, or holiday, attributing this to its liberal, progressive values—the “antithesis” of Trump’s nativism, populism, and unilateralism.

Mr Trump’s remarks came during a Monday White House interview with POLITICO’s Dasha Burns for a special episode of The Conversation.

He lambasted European nations as “decaying” due to unchecked immigration, zeroing in on London: “You have a mayor named Khan. He’s a horrible mayor.

“He’s an incompetent mayor, but he’s a horrible, vicious, disgusting mayor. I think he’s done a terrible job. London’s a different place.”

Mr Trump claimed Sir Sadiq has “a totally different ideology” and gets elected because “so many people have come in. They vote for him now.”

This feud dates back to Khan’s 2016 election as the first Muslim mayor of a Western capital. Mr Trump has repeatedly attacked him, including in a September UN speech alleging London was heading toward “Sharia law.”

Sir Sadiq has countered by labelling Mr Trump racist, sexist, misogynistic, and Islamophobic.

Echoing the US National Security Strategy, Mr Trump’s comments warn of Europe’s “civilizational erasure” from migration and lost identity. Sir Sadiq retorted: “I’m very comfortable having friends who are Christian, Jewish, Muslim, Hindu, Buddhist, Sikh. Diversity is a strength, not a weakness.”
