Donald Trump has repeatedly attacked London mayor Sadiq Khan, calling him “horrible, vicious, disgusting,” “incompetent,” a “disaster,” a “nasty person,” and a “stone cold loser,” and claiming he has done a “terrible job” running London and that immigration is why he gets elected. He has also suggested, without evidence, that London under Khan is moving toward “sharia law” and described European leaders as “weak” and “decaying” while singling Khan out in that criticism.

Quick Scoop: Core remarks

  • Trump has branded Sadiq Khan a “horrible, vicious, disgusting mayor” and “incompetent,” saying London has become a “different place” and that Khan has done a “terrible job.”
  • He has called Khan a “nasty person,” a “stone cold loser,” and “one of the worst mayors in the world,” often linking those insults to claims about crime and migration in London.
  • Trump has argued that Khan “gets elected because so many people have come in” to the UK and now vote for him, tying Khan’s support to immigration.

Timeline of the feud

  • The clash began around 2015, when Khan criticised Trump’s proposed Muslim travel ban as “ignorant,” after which Trump escalated with personal attacks and even challenged him to an IQ test.
  • During and after Trump’s UK visits, he repeatedly tweeted and spoke against Khan, attacking his handling of the 2017 London Bridge attack and London’s violent crime, and insulting him as a “stone cold loser” during state visit protests (including the “Trump baby” blimp).
  • In newer interviews and speeches (including at the UN and in later media sit‑downs), Trump has kept returning to Khan, using him as an example when attacking European immigration policy and city governance.

Notable quotes and themes

  • On Khan personally: Trump has called him “a horrible mayor,” “a disaster,” “very dumb,” “nasty,” and “vicious,” insisting he is “not a fan” and that Khan has “done a terrible job” for London.
  • On London and immigration: Trump says London has “changed” for the worse, claims the UK is letting people in “unchecked and unvetted,” and argues that these “newcomers” are the reason Khan keeps winning elections.
  • On “Sharia law”: Trump has said London “wants to go to sharia law” or suggested Khan is pushing that direction, despite there being no evidence of such a policy; these remarks have drawn accusations of racism and Islamophobia.

How Sadiq Khan has responded

  • Khan has accused Trump of being “racist, sexist, misogynistic and Islamophobic,” and has said the US president is “obsessed” with him, questioning why a world leader spends so much time attacking a city mayor.
  • He has refused to “dignify” some of Trump’s more inflammatory claims (like the Sharia allegation), while arguing that such rhetoric can embolden extremists or radicalise people.

Wider political and forum discussion

  • UK and international media often frame the feud as part of a broader culture‑war clash: Trump using Khan as a symbol of liberal, pro‑immigration urban politics, and Khan casting Trump as a danger to pluralistic, diverse cities.
  • On forums and talk shows, commenters frequently debate whether Trump’s attacks reflect genuine concern about crime and migration or are mostly personal and racially charged; others note that when pressed for detailed evidence, Trump tends to repeat broad claims rather than specifics.
