UCO recordings emerged overnight implicating PSOE secretary Santos Cerdán in commission payments from the Koldo corruption case, with intercepted conversations revealing discussions of 550,000 euros and contract arrangements. The party initially denied the evidence categorically, using the word "jamás" repeatedly.
By mid-morning, the Supreme Court offered Cerdán voluntary testimony on June 25th after finding "consistent evidence" against him. Eight audio recordings showed Cerdán allegedly managing construction company debts and kickbacks totaling 620,000 euros. The recordings also captured instructions to rig the 2014 PSOE primaries that Sánchez won: "without anyone seeing you, put in both ballots."
Coalition partners demanded Cerdán's resignation while Feijóo boycotted the EU anniversary celebration. By afternoon, Cerdán resigned from all positions. Sánchez held an emergency press conference apologizing to citizens, announcing an external audit, but ruling out early elections until 2027. The scandal escalated from the Koldo case to what opposition now calls "the Sánchez case."
