Ukraine’s new president, a comedian before he turned to statecraft, made a dramatic entrance to the political stage Monday by disbanding parliament minutes after his inauguration. Volodymyr Zelenskiy, who won 73% of the vote last month, justified his contentious decision on the grounds that the legislature, controlled by allies of the man he defeated, is riddled with self-enrichment. Elections to the Supreme Rada were scheduled for Oct. 27, which raised the prospect of Zelenskiy struggling to enact his agenda in the face of a hostile parliament over his first few months in power.
