The ongoing investigation into former Spanish Prime Minister José Luis Rodríguez Zapatero has raised serious concerns about the stability of the current left-wing government led by Prime Minister Pedro Sánchez. Zapatero, who served from 2004 to 2011, is formally under investigation for allegedly orchestrating a scheme to secure a €53 million government bailout for Plus Ultra airline, benefiting from influence peddling. Allegations suggest that he received significant commissions, including €250,000 funneled into a company owned by his daughters. This marks a historic moment as it is the first time a former prime minister in Spain faces such criminal scrutiny. As the investigation unfolds, political support for Zapatero is waning, with even his allies calling for explanations. Sánchez, already under scrutiny due to other legal issues involving his close associates, has defended Zapatero but may face pressure to resign or call elections if the situation escalates. The outcome of this investigation could be pivotal, potentially leading to the collapse of Sánchez's minority government, which relies on support from various parliamentary partners.
