Theresa May will step down as prime minister of the United Kingdom on June 7, she said Friday at No. 10 Downing St.
She came to the job in 2016 after U.K. voters backed plans to exit the European Union in a referendum. For the following three years, she attempted to navigate the difficult and complex process of making that happen.
"I feel as certain today as I did three years ago that in a democracy, if you give people a choice, you have a duty to implement what they decide," she said. "I have done my best to do that."
