(CNN)-For many Czechs, Sunday’s anniversary of the Velvet Revolution will be a bittersweet moment. Three decades after the collapse of the Communist regime, people will mark a dramatic moment in history amid allegations, confirmed by a court decision, that their prime minister collaborated with the StB, the Communist-era secret police.
Police said 250,000 attended anti-government demonstrations in Prague on Saturday, one day before the anniversary, when a non-violent demonstration led by students emboldened the nation to rise up against Communism.
They are demanding the resignation of PM Andrej Babis, a business tycoon who is listed as an StB agent in its official archives. Babis has consistently denied cooperating with the StB knowingly, saying he has been wrongly identified in the documents.
