Akcja Wyborcza Solidarność
In the 2001 elections the SLD and UP won 216 of the 460 seats, and were able to form a government with the support of the Polish People's Party (PSL). The former ruling party, Solidarity Electoral Action (AWS) based on the Solidarity trade union, lost all its seats. In its place several new right-wing parties emerged, such as the PO and the PiS.
