An estimated 250,000 Czechs rallied in Prague’s Letna Park this week to demand the resignation of Prime Minister Andrej Babis, in the biggest show of public discontent since the 1989 Velvet Revolution that overthrew the Communist regime. Babis, the billionaire head of the anti- establishment ANO party, is facing a criminal investigation for allegedly fraudulently obtaining $2.3 million in European Union subsidies for a firm he once owned. He’s also under EU investigation for conflicts of interest, because he has influence over subsidies that may be directed to his vast agriculture, media, and chemical holdings. Babis says he won’t resign even if he is charged with fraud. “Most of those allegations are not even true,” he said.
