Donald Tusk must undo years of populist subversion in Poland

THE HANDOVER was just as bitter as the years-long political brawl that preceded it. After losing an election in October, Poland’s hard-right Law and Justice (PiS) party finally ceded power on December 12th to a coalition headed by Donald Tusk, a veteran former prime minister. After PiS lost a vote of confidence in parliament, the party’s leader, Jaroslaw Kaczynski, took to the lectern to call Mr Tusk “a German agent”—a puerile insult PiS used throughout the campaign, referring to Mr Tusk’s German ancestry and his experience as president of the European Council.
