The fall of British Prime Minister Boris Johnson is one for the ages, a dramatic match for his personal charisma and the daring he showed in supporting Brexit that brought him to power. His failure in office is also a warning to the ruling Tories, and conservative parties around the world, that governing to the left on economics is a losing strategy.
Mr. Johnson led the Tories to an historic 80-seat majority in 2019 on a promise to get Brexit done after years of party vacillation and division. While wrangling continues with the European Union over Northern Ireland, the United Kingdom’s independence from the EU seems settled as a British political issue. He also saved Britain from the radical Labour Party of Jeremy Corbyn. This is no small achievement.
