"On July 17, 2024, the head of the SKW presented to the prosecutor's office a notice of suspicion about former Polish Defense Minister Mariusz Blaszczak committing a crime," the SKW said in a statement.
Blaszczak is accused of declassifying part of a document containing a Polish armed forces defense plan dubbed Warta. The document described how the Polish army would defend itself from a potential attack by Russia.
This part of the plan was declassified during the parliament election campaign in autumn 2023 and was used to accuse the opposition of being ready to give away a piece of Polish soil to the east of the Vistula River.
