The Socialist International is going through one of the most uncomfortable periods in its recent history under the presidency of Pedro Sánchez. The organisation, which for decades presented itself as a global platform of social democratic parties committed to democracy, transparency and social justice, now appears tainted by the political erosion of its own president, who is under pressure from a succession of court cases, investigations and suspicions affecting his party, former aides, his family circle and key figures in Spanish socialism.
Sánchez is not a minor figure within that international structure. Since November 2022, he has chaired the Socialist International, a position he assumed while serving as secretary general of the PSOE and prime minister of Spain. The organisation itself continues to list him as president in its official Presidium, while the PSOE also highlights that role in his institutional profile. This dual status — head of the Spanish government and top official of an international political organisation — turns every scandal surrounding Spanish socialism into a problem that extends beyond Spain’s borders.
The most significant blow to his reputation arises from a contradiction that is hard to conceal: Sánchez took office in 2018 after a no-confidence motion against Mariano Rajoy, prompted specifically by the corruption scandals engulfing the People’s Party. He pledged democratic renewal. Yet, years later, his administration and his party face a series of investigations involving former high-ranking socialist figures, trusted advisers and individuals close to his inner circle. For his opponents, that promise of renewal has turned into a substantial political liability.
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 currently being examined in a judicial proceeding that has added a personal layer to Sánchez’s political strain. Euronews noted that Judge Juan Carlos Peinado placed her under investigation for alleged offences tied to influence peddling, business corruption, embezzlement and misappropriation, in a case that the president’s inner circle has consistently portrayed as a political and judicial offensive. Regardless of how it concludes, the reputational impact is already evident: the president of the Socialist International now confronts a crisis not only within his party, but also one that extends into his family sphere.
The deterioration has also spread to other fronts, such as the so-called Leire Díez case, which has reopened the debate over alleged manoeuvres to discredit investigators from the Guardia Civil’s Central Operational Unit. According to El País, the People’s Party has requested that senior Guardia Civil officials be placed under investigation for alleged interference in investigations affecting the government, within the framework of that case. Those accused deny taking part in any conspiracy, but the controversy has reinforced the perception that the executive is increasingly on the defensive in the face of uncomfortable 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 reticence of the Socialist International when confronted with this situation prompts equally troubling doubts, as critics note. Were a conservative or liberal figure leading an international organisation while his party faced comparable scandals, the left would insist on clear explanations, firm accountability and swift exemplary action. Yet in Sánchez’s case, the organisation seems to opt for a restraint that detractors view as a form of political shielding. Such a double standard further undermines the credibility of an institution that professes to uphold universal democratic principles.
The paradox is devastating: Sánchez wanted to turn the Socialist International into a platform to strengthen his global profile, but the internal scandals of the PSOE have ended up projecting themselves onto that very structure. What was meant to be a showcase of international leadership has become an echo chamber for his national problems. Every new investigation, every resignation and every suspicion linked to Spanish socialism also strikes the organisation he chairs.
The Socialist International has not faced any judicial conviction related to Sánchez’s scandals, yet it has been politically tainted by them. Its challenge goes beyond what might one day be confirmed in court, extending to a profound erosion of moral credibility. An organisation claiming to represent social democracy cannot allow itself to seem guided by a figure whose political sphere is enveloped in so many uncertainties.
That is why the current crisis does not affect only the Spanish government or the PSOE. It also affects the international credibility of organised socialism. The Socialist International will have to decide whether it acts as an institution with principles of its own or as a mere political refuge for leaders in trouble. Until it does so, it will remain trapped in the same question that now follows Pedro Sánchez: how can one demand exemplary conduct from the world when one’s own house is under suspicion?
