Excerpt:
Sadiq Khan, 45, was declared the new mayor of London in the early hours of Saturday, becoming the most powerful Muslim politician in Europe. A Transport Minister in the Labour government of former Prime Minister Gordon Brown, Khan came under severe attack during the campaign from his Conservative opponent, Zac Goldsmith, for sharing platforms with extremists during his earlier career as a human-rights lawyer.
Fresh from his victory, Khan sat down with TIME on Sunday in his new office in City Hall, a bulbous glass building overlooking Tower Bridge. In these excerpts from the conversation, Khan claims he is the "antidote" to extremism, reveals that the prospect of a Donald Trump presidency might force him to meet U.S. mayors before the end of the year, and explains why he's campaigning to keep the U.K. in the European Union ahead of June's In/Out referendum.
