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 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 deteriorated further after the fall of Santos Cerdán, another key figure within Sánchez’s PSOE. Cerdán, who had been the party’s organisation secretary and one of the prime minister’s closest allies, was asked to step down, according to The Guardian, after a Supreme Court judge identified substantial signs suggesting his possible involvement in collecting commissions tied to public contracts, accusations he has rejected. The impact was particularly heavy because he was not a peripheral actor but a central organisational pillar 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.
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 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?
