London Mayor Sadiq Khan has expressed a willingness to meet Donald Trump, even as he warned that the US President could be “inadvertently radicalising people” and is “not a force for good”.The Labour politician dismissed the US President’s recent jibes, made during a visit to Scotland, where Trump labelled him “a nasty person” who has “done a terrible job”. Sir Sadiq stated such remarks were “water off a duck’s back”.However, speaking at the Edinburgh Festival Fringe, he admitted that the exchanges sometimes made him feel like he was “nine years old again” and “in the school playground”.But Sir Sadiq, speaking at the Political Party show with comedian Matt Forde, hit back at the US President, saying: “Somebody who has views like he does about black people, about women, about gays, about Muslims, about Mexicans, thinks I’m nasty.“Really. He is the leader of the free world, arguably the most powerful man in the world, and really.”He spoke out as he said that records showed since the middle of January this year – when Mr Trump began his second term in the White House – and July “there have never been more Americans applying to British citizenship and living in London”.The Mayor said: “So I think Americans have got good taste by and large.”He added that he hoped the President would come to London during his state visit to the UK next month, with Sir Sadiq stressing the “diversity” of the capital was a “strength, not a weakness”.Mayor of London Sir Sadiq Khan speaks with police officers during a walkabout in the West End of London More
