The article analyses the participation of nation-wide parties in the elections of local authorities: municipal councils and mayors. There is no empirical confirmation of the assumption that along with the democratic consolidation in Poland, political parties strengthen their presence in local governments. Between 2002 and 2018 the overall spread of national parties in local elections decreased, even though the national party system (at the parliamentary arena) was relatively consolidated. The level of political parties’ engagement in local authorities, despite the changes in the level of parties’ support, is relatively stable – and low: no more than one third of elected local officials in Poland are affiliated with political parties. Among parliamentary parties, only four: PO, PiS, PS and SLD, maintained their significant representation in local governments, but the share of power at the local level which they were able to win varied considerably. LPR and Samoobrona rapidly lost their significance after their defeat in the 2007 parliamentary elections. The “new parties” established later failed to secure representation at the local level. The analyses confirm a positive (and stable over time) relationship between the level of party politicisation of local governments and the size of the municipality.
