The party got 7.28% of votes in the 1993 parliamentary elections, and had 41 representatives in Sejm. In 1997 it got only 4.74% of votes and not having passed the required 5% threshold, it did not get into the Sejm. In the 2001 elections, it started together with Sojusz Lewicy Demokratycznej and managed to get 16 members of parliament. Some of them have since left to join newly created Socjaldemokracja Polska.
