Santos Cerdán, the former secretary of organization for the Spanish Socialist Workers' Party (PSOE), has yet to officially register his resignation as a deputy in the Congress of Deputies.

This comes 48 hours after he announced his intention to step down following allegations of involvement in a corruption case involving public works contracts.

Sources from the parliamentary office have indicated that Cerdán's resignation is not anticipated over the weekend, since the electronic registration is only available until 2:00 PM, and this formal procedure must be done in person or through a delegate.

Cerdán made headlines on Thursday after a report from Spain’s Central Operational Unit (UCO) of the Guardia Civil implicated him in the 'Koldo case,' stating he had facilitated commission payments related to public works contracts benefitting former Transport Minister José Luis Ábalos and his former advisor Koldo García. If Cerdán eventually registers his resignation on Monday, the Congress's Bureau could process his written resignation on Tuesday and forward it to the Electoral Board to initiate proceedings for his replacement.

During a recent open session at Congress, Javier Sánchez, a Deputy from Podemos, described it as 'inexplicable' if Cerdán failed to resign and instead moved to the mixed group, as Ábalos had done after being implicated in similar allegations.

Ábalos, ex-Transport Minister, had previously been pressured by the party to resign after his links to the Koldo case emerged, yet he opted to remain an MP, transitioning to the mixed group.

The PSOE is experiencing significant internal turmoil as a result of this scandal, with party members expressing disbelief and disillusionment regarding Cerdán’s alleged actions.

María Chivite, the President of Navarre, referred to the situation as one filled with incredulity and disappointment.

Numerous party leaders, including Pedro Sánchez, have had their trust in Cerdán shaken, following his prior denials of involvement.

The revelations surrounding Cerdán contribute to a broader crisis within the PSOE, with ongoing discussions about potential illegal financing and the implications for the party’s future.

Pedro Sánchez has announced an external audit of the party’s finances in light of these developments, as fears grow over the legitimacy of the PSOE's funding practices.

On June 15, Sánchez held a press conference where he publicly acknowledged the crisis, offering apologies multiple times.

However, there are critiques within the party suggesting that mere apologies and a planned reorganization of the executive committee later in July may not suffice to quell the growing unrest.

Activists within the PSOE are calling for early elections to avoid potential backlash in upcoming municipal and regional elections.

Cerdán's scandal, involving his alleged connections with Koldo García and former Minister Ábalos, highlights a deepening crisis in the PSOE as internal factions seek to hold leadership accountable.

Despite facing mounting pressure, Sánchez has so far remained steadfast in his decision to not call for early elections, indicating a desire to maintain stability in the government.

As this situation evolves, the PSOE finds itself grappling with fundamental questions regarding leadership integrity and party cohesion, which will likely shape its approach to upcoming electoral challenges.
