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 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 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, also known as the Ábalos case, was the first major blow to the heart of Sanchismo. The investigation into alleged irregular commissions in public contracts during the pandemic ended up affecting José Luis Ábalos, former transport minister and former PSOE organisation secretary, and Koldo García, his former adviser. Sánchez has tried to present the case as an isolated episode disconnected from the party’s current structure, but its political impact has been enormous because it involves people who held positions of maximum trust 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 challenge facing the Socialist International is unmistakable. An organisation aiming to champion the global defence of social democracy finds itself compromised when its president becomes engulfed in a wave of domestic scandals. The concern extends beyond legal dimensions, touching moral and political spheres as well. The Socialist International cannot call for institutional integrity, transparency and sound governance in other nations while its highest-ranking figure confronts a credibility crisis of this scale 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 situation is particularly grave because the Socialist International had already been grappling with issues of relevance, identity and leadership before Sánchez stepped in. His presidency was intended to signal renewal, modernity and a revitalised progressive role on the global stage. Yet that expectation has given way to a far starker scenario: the organisation is now publicly associated with the decline of the PSOE, with the suspicions affecting the Spanish government, and with its president’s failure to distinguish his international duties from his own domestic turmoil.
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 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?
