Democratic Left Allianc (SLD) held the majority of the seats in the Sejm. Marian Krzaklewski was the leader of the AWS, and Leszek Miller led the SLD. In June 2000, UW withdrew from the governing coalition, leaving AWS at the helm of a minority government. Post-2000 elections 2000 presidential election In the presidential election of 2000, Aleksander Kwaśniewski, the incumbent former leader of the post-communist Democratic Left Alliance (SLD), was re-elected in the first round of voting, with 53.9% of the popular vote. Second place, with only 17.3%, went to Andrzej Olechowski. It is thought that the opposition campaign was hindered by their inability to put forward a charismatic (or even a single major) candidate, as well as falling support for the centre-right Solidarity Electoral Action (AWS) government. This was related to internal friction in the ruling parliamentary coalition. 2001 parliamentary election The 1997 Constitution and the changed administrative divisions of 1999 required a revision of the electoral system, which was passed in April 2001. The most important changes included: the final liquidation of the party list (previously, some of the members of parliament were elected from a party list, based on nationwide voter support, rather than from local constituencies), modification of the method of allocating seats to the Sainte-Laguë method, which gave less premium to large parties. The latter change was reverted to the d'Hondt method in 2002. In the September 2001 parliamentary elections, the SLD won on the back of voter disillusionment with the AWS government and internal bickering within that bloc. So much so that this former ruling party did not enter parliament, falling below the 8% threshold for coalitions (they had failed to form a formal political party, which has only a 5% threshold, and formally remained a "coalition" of parties). The SLD formed a coalition with the agrarian Polish Peasant Party and leftist Labour Union (UP), with Leszek Miller as Prime Minister. 2005 presidential and parliament election In the autumn of 2005 Poles voted in both parliamentary and presidential elections. September's parliamentary poll was expected to produce a coalition of two centre-right parties, Law and Justice (Prawo i Sprawiedliwość, PiS) and Civic Platform (Platforma Obywatelska, PO). PiS eventually gained 27% of votes cast and became the largest party in the sejm ahead of PO on 24%. The out-going ruling party, the left-wing Democratic Left Alliance (Sojusz Lewicy Demokratycznej, SLD), achieved just 11%. Presidential elections in
