Newly-elected mayor of London Sadiq Khan has told the publication Time that he could not visit the United States because of his Muslim faith if Trump were elected president.

Khan became London's first Muslim mayor on Saturday. He told the publication that Trump's controversial policy stances could make it hard for him to visit the world's largest economy and one of the U.K.'s strongest international allies.

"If Donald Trump becomes the president I'll be stopped from going there by virtue of my faith, which means I can't engage with American mayors and swap ideas," Kahn told Time in an interview. "I'm confident that Donald Trump's approach to politics won't win in America."
