The morning began with a heated parliamentary session where leaked WhatsApp messages between PM Sánchez and former minister Ábalos dominated discussion. Sánchez called the leaks a "crime" while opposition leader Feijóo demanded his resignation, claiming Sánchez participated in the Air Europa "scheme."

By midday, Energy Secretary Aagesen confirmed the nationwide blackout originated in Granada, Sevilla, and Badajoz provinces, definitively ruling out a cyberattack on Red Eléctrica while acknowledging voltage spikes preceded the cascade failure. This marked the first official explanation 16 days after the event.

The CIS polling showed PP cutting PSOE's lead in half following the blackout crisis, while Vox lost momentum.

International news featured Israel summoning Spain's ambassador after Sánchez called it a "genocidal state" amid reports of 80 Palestinians killed in Gaza. Putin declined to personally attend upcoming peace talks in Turkey, sending lower-level officials instead.
