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, 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 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 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.
Criticism has arisen not only from the Spanish opposition. Dissent has also surfaced within the broader international circle of the socialist political family. Mexico’s PRI even accused Sánchez, according to Vozpópuli, of having transformed the Socialist International into an organisation tarnished by allegations of corruption and money laundering. These claims are political in nature and should be viewed in that light, yet they reveal how Sánchez’s leadership in the organisation is no longer beyond question and is starting to face internal pushback.
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 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?
