Britain’s ambassador to the U.S., Kim Darroch, resigned today following the fallout from leaked cables in which he called Trump “inept,” “insecure” and “incompetent.” In cables going back as far as 2017, Darroch questioned whether the Trump administration “will ever look competent.” He also said Trump’s presidency could “crash and burn,” and voiced fears that he may launch an attack on Iran. On Tuesday, Trump continued to lash out at Darroch, tweeting, “The wacky Ambassador that the U.K. foisted upon the United States is not someone we are thrilled with, a very stupid guy.” He also called the outgoing prime minister “foolish” and blamed her for creating a mess out of Brexit.

Prime Minister May, who said earlier this week she stood by Darroch, said in Parliament after his resignation today, “Sir Kim has given a lifetime of service to the United Kingdom and we owe him an enormous debt of gratitude. Good government depends on public servants being able to give full and frank advice. … I hope the House will reflect on the importance of defending our values and principles, particularly when they are under pressure.” Opposition Labour Leader Jeremy Corbyn also lamented Darroch’s resignation.
