Sadiq Khan

As immigration concerns were driving the push for Brexit, Londoners elected Sadiq Khan, the son of Pakistani immigrants, as their mayor in May 2016, making him the first Muslim to hold that position in a major European capital. I met with him a few weeks after his election and was impressed by his ambitious agenda. For instance: he has made tackling climate change a top priority, and he is showing how cities—on their own and by working together—can accelerate our progress.

He has also been a voice of reason on Brexit, recognizing that the U.K. will be stronger by maintaining a close relationship with Europe. And at a time of increasingly divisive political rhetoric, he has been an important voice for tolerance and unity. When President Trump retweeted videos from a British anti-Muslim group, Sadiq rightfully denounced it.

He’s a rising star who has a bright political future. Somewhere down the road, I wouldn’t be at all surprised to see him living at 10 Downing Street.
