The 2010 Polish local elections were held in two parts, with its first round on November 21 and second on December 5. The first round included elections of deputies to provincial voivodeship sejmiks, as well for gmina and powiat councilors. The second round of elections were marked for mayors, borough leaders, and other positions decided by runoff elections. The local elections were seen as a test to the ruling Civic Platform and Polish People's Party coalition government under Prime Minister Donald Tusk.
As the first polls since the July presidential elections, which saw Civic Platform candidate Bronisław Komorowski defeat Law and Justice MP and former Prime Minister Jarosław Kaczyński, the 2010 local elections were characterized as a test to the administration of Donald Tusk. In the weeks prior to the elections, polls conducted by the CBOS Institute showed the ruling Civic Platform party with a comfortable lead over its rivals. The opposition Law and Justice electoral campaign faced multiple challenges prior to the elections. Polls published in the days leading up to the first round indicated low support for the party. In a related addition, a severe internal party crisis regarding Kaczyński's leadership and the party's ideological direction, simmering among several of the party's more moderate MPs in the Sejm for several months prior, exploded into the open days before the election. The rebel MPs, led by expelled party member Joanna Kluzik-Rostkowska, formed the Poland Comes First parliamentary group on November 16. The party split further undermined confidence to the government's opposition.
