During the debate on the establishment of a preliminary investigative committee, Triantopoulos stated: “For me, politics is not a profession, and holding onto a position is not an end in itself. Today, I submit my resignation as Deputy Minister of Civil Protection and Climate Crisis.”

His resignation had been anticipated in recent days, as he had previously signaled his intent to step down following new developments in the Tempi railway disaster investigation, specifically regarding the alleged cover-up of the accident site. Triantopoulos had pledged to resign once the process for forming the investigative committee moved forward.
