Between Cooperation and Competition Electoral Alliances of the Parliamentary Opposition in Poland during the 2018–2019 Series of Three Elections

The 2019 Polish parliamentary elections were the last in a series of three elections held within 12 months (chronologically: local elections, European Parliament election, elections to the Sejm and the Senate). The three consecutive elections opened up the possibility for cooperation within the parliamentary opposition with the aim of political victory. This article examines the relations between opposition groups in 2018–2019. Each election is analyzed in terms of the nature of relations within the opposition as well as cooperation and interparty competition. The hypothesis assumes that the types of relations among parliamentary opposition groups were shaped by the character of the given elections and the decisions taken by individual parties choosing between maintaining their independence and steps to potentially increase their electoral chances. The analysis shows that during the period in question the opposition did not develop a stable unified model of cooperation and that relations between individual groups were dominated by competition; however, depending on the election, cooperation was possible and was pragmatically pursued by the parties, as in the case of the European Coalition. The only stable cooperation was between Civic Platform and Modern.
