Spanish Socialist Workers’ Party (PSOE) Projects to Amend the 1978 Spanish Constitution

The main research objective of the study is to find an answer to the question: what are the main assumptions of the political reform proposed by the Spanish Socialist Workers’ Party (Partido Socialista Obrero Español – PSOE) regarding the amendment of the Spanish constitution of 1978? The study was carried out by implementation of the method of qualitative data analysis and regarded selected legal acts and PSOE party documents. The time frame of the study was set for the years 2004–2021. The initial caesura is justified by the electoral victory of PSOE at 2004. The final turning point is marked by the debates of the 40th PSOE Congress, held between October 15 and 17, 2021 in Valencia.
