LONDON - US President Donald Trump has attacked London Mayor Sadiq Khan as a "stone cold loser" who has done  "terrible job" as London Mayor ahead of the US President's three-day state visit to London. 

Khan on Sunday criticised Trump and compared him to fascist leaders in the 20th Century.

In a tweet, Donald Trump wrote that Khan "who by all accounts has done a terrible job as Mayor of London, has been foolishly "nasty" to the visiting President of the United States, by far the most important ally of the United Kingdom. He is a stone cold loser who should focus on crime in London, not me......

"Kahn [sic] reminds me very much of our very dumb and incompetent Mayor of NYC, de Blasio, who has also done a terrible job - only half his height. In any event, I look forward to being a great friend to the United Kingdom, and am looking very much forward to my visit. Landing now!"

In a piece for the Observer newspaper on Sunday, Khan wrote: "President Donald Trump is just one of the most egregious examples of a growing global threat. The far right is on the rise around the world, threatening our hard-won rights and freedoms and the values that have defined our liberal, democratic societies for more than 70 years."
