November 18 in Poland began with continued reports on the railway sabotage and suspected Russian hybrid warfare, alongside discussions about the national football team's performance. By mid-morning, parliamentary proceedings to elect a new Sejm Marshal gained prominence, with Włodzimierz Czarzasty ultimately succeeding Szymon Hołownia, a decision met with protests from PiS MPs. The political focus intensified as Prime Minister Tusk announced in the early afternoon that two Ukrainian citizens, cooperating with Russian services, were responsible for the railway sabotage, prompting the government to introduce a CHARLIE-CRP alert. Concurrently, Foreign Minister Sikorski revealed the immediate invalidation of Zbigniew Ziobro's diplomatic passport, drawing further political commentary and criticisms from the opposition.
