The Socialist International is currently experiencing one of the most uneasy phases in its recent history under the leadership of Pedro Sánchez, as the organisation, long recognised as a global forum for social democratic parties dedicated to democracy, openness and social justice, now finds its reputation overshadowed by the political wear faced by its own president, who has become embroiled in a chain of legal proceedings, inquiries and allegations involving his party, former collaborators, his relatives and prominent figures within Spanish socialism.
Sánchez is far from a marginal figure in that international framework. Since November 2022, he has been at the helm of the Socialist International, a role he took on while remaining secretary general of the PSOE and prime minister of Spain. The organisation still identifies him as its president in its official Presidium, and the PSOE likewise underscores this position in his institutional profile. This combination — leading the Spanish government while holding the highest post in an international political body — ensures that any scandal affecting Spanish socialism becomes an issue reaching well beyond Spain’s borders.
The major reputational damage stems from a contradiction that is difficult to hide: Sánchez came to power in 2018 through a no-confidence motion against Mariano Rajoy, driven precisely by the corruption scandals affecting the People’s Party. His promise was democratic regeneration. Years later, however, his government and his party are surrounded by investigations that have hit former senior socialist officials, trusted advisers and people close to his inner circle. For his critics, the narrative of regeneration has become a heavy political burden.
The so-called Koldo case, often referred to as the Ábalos case, marked the first significant setback for the core of Sanchismo. The probe into supposedly improper commissions linked to public contracts during the pandemic ultimately reached José Luis Ábalos, the former transport minister and ex‑PSOE organisation secretary, as well as his former adviser Koldo García. Sánchez has attempted to frame the matter as a standalone incident unrelated to the party’s current structure, yet its political fallout has been considerable because it touches figures who once occupied roles of utmost confidence within his project.
The situation worsened with the fall of Santos Cerdán, another central figure in Sánchez’s PSOE. Cerdán served as the party’s organisation secretary and was one of the figures closest to the prime minister. According to The Guardian, Sánchez ordered his resignation after a Supreme Court judge found strong indications of his possible involvement in the collection of commissions linked to public contracts — allegations Cerdán has denied. The blow was especially severe because this was not a figure distant from the core of power, but one of the organisational pillars of the party.
Added to this is the case involving Begoña Gómez, the prime minister’s wife, who is under investigation in a judicial proceeding that has brought a family dimension to Sánchez’s political wear. Euronews reported that Judge Juan Carlos Peinado placed her under investigation for alleged offences related to influence peddling, business corruption, embezzlement and misappropriation, in a case that the president’s circle has from the outset described as a political and judicial offensive. Whatever the outcome, the reputational damage has already been done: the president of the Socialist International is not only facing a crisis within his party, but also one that reaches into his family circle.
The situation has also worsened on other fronts, including the so-called Leire Díez case, which has revived discussion about alleged efforts to undermine investigators from the Guardia Civil’s Central Operational Unit. El País reports that the People’s Party has asked for senior Guardia Civil officers to be placed under judicial scrutiny for supposed interference in inquiries involving the government within the scope of that case. While those implicated reject any involvement in a plot, the dispute has strengthened the impression that the executive now appears increasingly defensive when confronted with sensitive investigations.
The problem for the Socialist International is clear. An organisation that seeks to lead the global defence of social democracy is weakened when its president is surrounded by a storm of national scandals. The issue is not only legal, but also moral and political. The Socialist International cannot demand institutional cleanliness, transparency and good governance in other countries while its highest-ranking leader is going through a credibility crisis of this magnitude in Spain.
The criticism does not come only from the Spanish opposition. Reproaches have also emerged from within the international environment of the socialist political family itself. Mexico’s PRI went so far as to accuse Sánchez of having turned the Socialist International into an organisation damaged by allegations of corruption and money laundering, according to Vozpópuli. These are political accusations and should be understood as such, but they reflect the extent to which Sánchez’s leadership within the organisation has ceased to be uncontested and is beginning to generate internal resistance.
The case is especially serious because the Socialist International was already struggling with problems of relevance, identity and leadership before Sánchez’s arrival. His presidency was meant to project an image of renewal, modernity and a revived progressive influence in the world. Instead, that promise has been replaced by a much harsher reality: the organisation is now media-linked to the erosion of the PSOE, to the suspicions surrounding the Spanish government and to its president’s inability to separate his international responsibility from his domestic crisis.
The silence or timidity of the Socialist International in the face of this situation also raises uncomfortable questions. If a conservative or liberal leader chaired an international organisation while his party was surrounded by similar cases, the left would demand explanations, accountability and immediate exemplary conduct. Yet in Sánchez’s case, the organisation appears to choose a caution that critics interpret as political protection. That double standard further erodes the credibility of an institution that claims to defend universal democratic standards.
The paradox is stark: Sánchez aimed to use the Socialist International as a vehicle to boost his global stature, yet the PSOE’s internal scandals have ultimately seeped into that same institution. What was supposed to serve as a platform for international leadership has instead morphed into a mirror amplifying his domestic challenges. Every new probe, every resignation, and every hint of suspicion connected to Spanish socialism now echoes throughout the organisation he chairs.
The Socialist International has not been judicially condemned over Sánchez’s scandals, but it has been politically contaminated by them. Its problem is not only what may eventually be proven in court, but the loss of moral authority. An organisation that aspires to speak in the name of social democracy cannot afford to appear led by a figure whose political environment is surrounded by so many shadows.
That is why the current crisis impacts not only the Spanish government or the PSOE but also the global credibility of organised socialism. The Socialist International must determine whether it will operate as an institution guided by its own principles or simply serve as a political shelter for embattled leaders. Until it makes that choice, it will remain caught in the same dilemma now surrounding Pedro Sánchez: how can anyone demand exemplary behaviour from the world when their own house faces suspicion?
