Even Theresa May’s opponents are taken aback by Trump’s Brexit attack

President Trump kicked off his visit to the U.K. by knifing his host, Prime Minister Theresa May, in the front. Metaphorically, of course. In an interview with the Sun, Trump said May’s long-awaited blueprint for Brexit, published this week, would “probably kill” any future trade deal between the U.S. and U.K. He also said May’s arch-rival, Boris Johnson -- who resigned as foreign secretary on Monday in protest at the blueprint -- would “make a great prime minister.”
