Spanish politics has transitioned through several phases of bipartisanship, moving from a failed two-party system to a current “blocista” stage. In this contemporary landscape, the two dominant parties, the PSOE and the PP, rely on their respective political extremes to maintain power, while parties like Vox gain support from disaffected voters.

Internal developments are also occurring within specific political entities. Catalunya en Comú has registered a new entity called Somos Partido Progresista (SPP), which leaders describe as an instrumental move to secure the brand name. Simultaneously, the PSOE is facing internal friction following primary elections for mayoral candidates in Madrid and Oviedo, leading to political tensions and a resignation in Oviedo.
