On June 17, former Spanish prime minister José Luis Rodriguez Zapatero, who served from 2004 to 2011, will enter the record books as the first ex-leader of comparable stature to testify at the National Court under summons from Judge José Luis Calama.

Zapatero's long-standing image as a neutral broker in Venezuela since 2015 has faded, revealing accusations that he helped shield the regime and may have bypassed standard procedures to secure a 2021 rescue package for the struggling Venezuelan carrier Plus Ultra amid the COVID-19 crisis.

Calama is probing claims that Zapatero directed a group that gained from advocacy work tied to Plus Ultra, based on findings reported by ABC News.

The magistrate has traced roughly 1.95 million euros routed through shell entities, altered records, and hidden financial paths, according to NBC News as cited by Quartz on May 20.

Pressure from France, Switzerland, and the United States has placed Zapatero under global scrutiny, with his court appearance now imminent.

Calama's 800-page filing claims Zapatero wielded decisive sway over Venezuelan oil deals, requiring foreign purchasers of crude to route their proposals directly through him.

The indictment further states that a scandal of this magnitude, centered on a former prime minister, could only arise amid significant political protection in Spain.

Shifting Details in Court Files Spark Daily Debate Across Spain

Fresh revelations from the case files appear in Spanish outlets each day and fuel ongoing conversations in public spaces.

Bailout funds for Plus Ultra reportedly served to move millions toward overseas networks active in Venezuelan gold and oil commerce. After the filing, the judge froze about 490,000 euros in accounts linked to Zapatero and those of his daughters' marketing firm, What the Fav.

UDEF, the National Police unit focused on money laundering and major graft, carried out searches, among them four coordinated operations last month at Zapatero-linked sites and other premises, after an earlier action at Plus Ultra headquarters at Adolfo Suárez Madrid-Barajas Airport.

Calama asserts that Zapatero and associates received 1.95 million euros, or about 2.11 million dollars, in improper gains connected to the airline rescue.

The judge has sought international arrest warrants for primary Plus Ultra shareholders Rodolfo Reyes and María Aurora López of Venezuela on charges including criminal organization membership, embezzlement, and laundering, as noted by Democrata media on May 25.

El País reported on May 19 that the Attorney-General's Office under Alejandro Luzón has examined the destination of the March 2021 bailout funds since 2024, prompted by queries from Swiss and French authorities over suspected laundering in their jurisdictions.

During a 12-hour operation on May 28 at the PSOE headquarters on Ferraz Street in Madrid, the Civil Guard's UCO unit, acting on court orders, uncovered an alleged network aimed at undermining judicial proceedings.

Media accounts indicate the UCO recovered substantial evidence, including luxury jewels valued near one million euros, from Zapatero properties. The former leader maintains the items represent inherited family property of his wife.

While serving as mediator in Venezuela, Zapatero persuaded Sánchez to approve a 53 million euro rescue for the small Venezuelan airline Plus Ultra during the pandemic, an amount well above the carrier's value. Judge Calama notes a Dubai shell company was formed to obscure the fund trail.

One direct outcome was a visit to Spain by Venezuelan vice president Delcy Rodriguez, Maduro's deputy, who landed at Barajas with numerous heavy suitcases and without standard checks. The contents remain under examination.

Portions of Zapatero's earnings from Venezuelan dealings may have passed through his daughters' marketing agency via the firm Analisis Relevante. The daughters face no charges so far. Reports suggest Zapatero might negotiate to protect them if needed, which could draw greater attention to Sánchez.

Sánchez Allies in Graft Cases Gain Public Recognition

Among ongoing graft matters involving Sánchez's inner circle, names such as Abalos, Koldo, and Aldama have grown familiar throughout Spain in recent years.

José Luis Abalos, formerly Sánchez's transport minister and a deputy, remains in custody awaiting sentencing this week after three years. Sánchez has distanced himself from Abalos.

Abalos and aide Koldo García are expected to receive extended terms for their roles in the Caso Koldo affair, which involved supplying substandard COVID masks to health services during the pandemic.

Víctor de Aldama is accused of enabling the mask dealings and has shared information with investigators. Aria media observed that recent hearings showed Aldama moved freely within the Transport Ministry complex as if part of the staff.

The matter has become a significant burden for Sánchez. Aldama's outcome may determine the direction for Zapatero and, by extension, the prime minister.

Should Aldama evade prison, a political analyst close to The Jerusalem Post indicated that Julio Martinez, Zapatero's close associate also under scrutiny, might choose to assist the court.

Analisis Relevante, the network that transferred funds to Zapatero's daughters, is run by Martinez and is now said to have been set up solely for laundering kickbacks from Plus Ultra. In 2020, as the airline sought Zapatero's help for a bailout, his daughters received an initial 25,400 euros from the firm.

On May 19, during a search of Zapatero's offices, UDEF found a concealed safe holding over 100 luxury watches, jewels, and items, plus Martinez's handwritten records of Venezuelan transactions.

Earlier, on December 11, UDEF officers searching Martinez's residence discovered 286,000 euros in cash concealed in boxes, radiators, and golf bags.

A broad effort to conceal evidence is alleged to have begun on the day Sánchez's wife, Begoña Gómez, was charged with corruption, influence peddling, and embezzlement following a two-year probe in an April 11 ruling made public two days later.

Sánchez then told the nation he would take four days to consider resigning. He is said to have convened his close aide Santos Cerdan, then PSOE organizational secretary who stepped down last year after a judge cited firm proof of kickbacks on public contracts, and directed interference in cases against him. Cerdan was occupied, so Leire Diez handled operations for him, according to the analyst.

When UCO agents raided Diez's home in December as part of a sealed National Court probe into judicial obstruction, they seized devices, notebooks, and diaries containing evidence of alleged efforts to block justice and derail PSOE or government-related graft cases. She was detained and later freed on bail.

In the Ferraz headquarters search last month, the UCO obtained material connecting Diez's activities and expenses to party leadership.

Records also covered operations at SEPI, Correos, Tragsa, and the state news agency EFE.

Diez's materials detail years of plans, contacts, meetings, and notes on suspected irregularities in public bodies she knew through her work or from former SEPI president Vicente Fernández, with whom she had a personal relationship and who also faces charges.

Her stored information points to direct attempts by then-transport minister Abalos, Sánchez's former number two, to alter evidence.

UCO Gathers Evidence of Efforts to Halt Inquiry

Media reports state the UCO has documented attempts at multiple administrative levels, including within the Civil Guard, to end the unit's work.

On Wednesday, Democrata media reported that the State Attorney-General's Office confirmed to National High Court Judge Santiago Pedraz, who oversees the Diez matter, the occurrence of two meetings involving Diez, Cerdan's lawyer, and a former senior official tied to ex-attorney-general Álvaro García Ortiz. Ortiz resigned in 2025 after the Supreme Court found him guilty of revealing secrets in an attack on Madrid President Isabel Díaz Ayuso, a vocal Sánchez critic.

Diez is another figure Sánchez claims not to know, repeating his familiar responses of ignorance.

The analyst told the Post that Diez represents the key breakthrough from which many connections will emerge.

At a moment when his career could be concluding, Sánchez sought to shift focus by commending Arab Barghouti, son of the convicted terrorist Marwan Barghouti, who addressed the crowd at Barcelona's Primavera Sound festival on June 6 ahead of the opening performance, an event that has drawn pro-Palestinian activism. Barghouti expressed thanks to Barcelona residents for backing the Palestinian cause.

Sánchez met him after the address and praised his resistance. The prime minister later shared a video of the speech on his official Instagram account, adding thanks for speaking out.

That same morning, Sánchez had welcomed Pope Leo XIV to Spain following his own recent trip to Rome. Critics in media and public noted his choice to skip additional papal events and instead use the government plane to attend the music festival with his wife.

The pope's visit, popular across Spain and drawing visitors nationwide to Madrid, was timed by Sánchez as one of his effective diversions from the legal proceedings, the analyst observed.

Sánchez is described by the analyst as merely an empty suit, the suitable European leader for the emerging order: opposed to America and Israel, quick to join trends and greet the son of a terrorist at a Barcelona festival in a region with notable antisemitism.

The analyst portrayed the head of the Socialist International as attractive and capable of playing the Western leader role against Trump and Israel, yet ultimately an empty suit.

According to Aldama's testimony to the judge, Zapatero allegedly arranged an oil deal for six million barrels of Venezuelan crude worth about 250 million euros to direct kickbacks to the PSOE and the International Socialist. This reportedly served as the means by which Zapatero secured Sánchez's position as head of the International Socialist.
