⌨Following Santos Cerdán’s defiant Senate appearance regarding 'Caso Koldo,' editorial attention on December 18 shifted to the Extremadura regional elections. By mid-morning, Maria Guardiola and PP leadership denounced a 'theft of votes' after three post offices were burglarized, framing the incident as a democratic threat. By early afternoon, authorities confirmed 124 ballots were stolen but attributed the act to common crime, later recovering the burnt remains of the safe and voting papers. Despite the Civil Guard’s findings, the PP continued to suggest electoral interference, a narrative that dominated the evening’s televised debate, which Guardiola notably did not attend.
Simultaneously, the 'Caso Koldo' investigation expanded as the Senate summoned former Prime Minister Zapatero to testify. In Catalonia, the regional government approved new regulations on seasonal rentals, while in Brussels, massive farmer protests against the EU-Mercosur deal escalated into violent clashes with police.
