Theresa May is resigning as prime minister of the United Kingdom after her latest attempt at a deal for Britain to leave the European Union failed.

“It is, and will always remain, a matter of deep regret to me that I have not been able to deliver Brexit,” May said Friday in front of 10 Downing Street. She urged her successor to do so. “To succeed, he or she will have to find consensus in Parliament where I have not. Such a consensus can only be reached if those on all sides of the debate are willing to compromise.”
