The PSOE is set to hold primaries to choose its regional and municipal candidates. This process will take place over three periods: July, September, and November. The party's federations will have the flexibility to apply these time frames according to their interests.

Further information on the specifics of the primaries can be found through El País, as details of the process are still emerging. The primaries are part of the preparations for the elections scheduled for next year, and the party is introducing a new approach with the three-stage selection process.
