The day's focus remained firmly on the 'Caso Koldo' investigation, with Santos Cerdán's appearance before the Senate commission dominating headlines from morning through evening. Cerdán, newly released from prison, strongly defended his innocence, repeatedly denying any involvement in corruption or illegal PSOE financing. He characterized the investigation as a "persecution of the Inquisition" and a "judicial coup," refusing to answer specific questions while challenging the ethical standing of his critics within the PSOE.
Later in the day, a judge opened a secret investigation into alleged PSOE payments, further deepening the scandal. Throughout, Cerdán linked his judicial troubles to his photograph with Puigdemont in Brussels.
