Thanks, however, to his incendiary comments about immigrants and Muslims, Mr. Trump has moved from being a buffoonish figure on the margins of British consciousness to the center of political debate. After Mr. Trump said that he, if president, would stop Muslims entering the United States, more than half a million people signed a parliamentary petition, thus requiring a debate in Parliament on whether to bar him entry to Britain.
