The largest opposition group, Civic Platform (PO), soundly defeated the ruling Law and Justice (PiS) party and its allies.Law and Justice's former minor coalition partners, the League of Polish Families and the Self-Defense of the Republic of Poland suffered an enormous voter backlash, failing to cross the 5% electoral threshold in order to enter the Sejm.Early elections were called after the Sejm voted for its dissolution, due to serious allegations of massive corruption on the part of Andrzej Lepper, leader of the Self-Defense of the Republic of Poland, whose party served as a junior coalition partner to the government of Prime Minister Jarosław Kaczyński.Civic Platform consequently formed a coalition majority government with the Polish People's Party.The Civic Platform formed a coalition majority government with the agrarian centrist Polish People's Party.
