A judge investigating Spain’s former Prime Minister José Luis Rodriguez Zapatero for alleged influence peddling has expanded his politically explosive probe to the Socialist’s daughters, a court said on Thursday.
The investigation into a titan of the Spanish left comes as a string of other graft probes into Socialist Prime Minister Pedro Sánchez’s family and former top political allies have threatened to topple the government.
Zapatero, who governed Spain from 2004-2011, was placed under formal investigation last month suspected of influence peddling in connection with the €53 million bailout of small airline Plus Ultra in 2021.
Investigating judge José Luis Calama has said evidence exists to suggest Zapatero headed a structure that used “opaque financial channels” to conceal the movement of money and obtain bribes for his manoeuvring to achieve the bailout.
Calama notified Alba and Laura Rodriguez Espinosa “to allow them to appear in the proceedings as persons under investigation and exercise their right of defence”, the Audiencia Nacional court said in a statement on Thursday.
The judge said both daughters ran a company “whose operations appear circumstantially to be linked to the scheme under investigation,” justifying their inclusion in the probe.
The company held “an instrumental role in the channelling, concealment or facilitation of relevant operations,” the statement added.
Police in May searched the offices of the company.
Zapatero’s secretary Gertrudis Alcazar was also placed under investigation.
The former premier defended his innocence during a three-hour hearing before Calama on Wednesday, becoming the first former or serving Spanish head of government to declare as a suspect in a corruption investigation.
He said he had always acted “with decency and honesty” and denied illicitly owning companies, money or financial products.
A police search of Zapatero’s office found jewellery and luxury watches valued at €1.3 million, leading Calama to probe additional alleged offences of tax fraud and smuggling.
Zapatero’s entourage attributes the hoard to a family inheritance.
Spanish media reported that the jewels were a gift from a former king of Saudi Arabia.
Clean up politics
Sánchez vowed to clean up Spanish politics when he took power in 2018 after the main conservative Popular Party was convicted in its own graft affair.
But the investigation into Zapatero imperils the reputation of a “moral beacon” for Sánchez and the Socialists, Astrid Barrio, a political science professor at the University of Valencia, told the AFP news agency.
A two-year-long investigation into Sánchez’s wife Begona Gomez for alleged influence peddling had already shaken the government, with a decision to send her to trial potentially imminent.
Verdicts are also due in separate corruption trials of Sánchez’s former right-hand man José Luis Abalos and his brother David Sánchez.
Recent revelations about an ongoing police probe into a former Socialist activist suspected of leading a plot to sabotage investigations into Sánchez’s entourage have piled further pressure on the government.
Amid the relentless stream of negative headlines, the Socialists have suffered four regional election drubbings since late 2025, in a possible precursor to next year’s national vote.
The conservative and far-right opposition have demanded Sánchez’s resignation and early elections, but the prime minister insists he will see out his term until 2027.
