Abstract
The article analyses the determinants of the selection of candidates for the European Parliament in Polish political parties and the relationship between the way candidates are selected and the personal stability of the Polish representation in the EP. The study is based on the analysis of party documents and data obtained in semi-structured interviews with MEPs elected in the period 2004–2019. The level of variability and stability of the personal composition of the Polish delegation is presented in terms of the four parties that have been part of the Polish representation in all previous terms. The stability of representation is not a leading motive in the intraparty selection of MEP candidates. The domination of informal criteria in creation of the electoral lists further weakens the link between selection process and personal stability of the Polish delegation in the EP.
