When European Union leaders gather in Brussels on Thursday they will have a guilty secret: among them will sit the leader of a member state that is no longer a democracy. Viktor Orbán, Hungary’s prime minister and de facto supreme leader, will sit there smiling as a democrat among democrats, but in reality he has demolished liberal democracy in his country over the last decade. Adding insult to injury, he has used EU taxpayers’ money to consolidate his illiberal regime.
