Polish Deputy Prime Minister and Minister of National Defense Wladyslaw Kosiniak-Kamysz has ordered the declassification of information on Warsaw's military assistance to Kyiv provided since the start of Russia's full-scale invasion of Ukraine.

He announced the decision in a post on X on Sunday, following the emergence in the Polish media of confidential information alleging that Poland transferred interceptor missiles for Patriot air defense systems to Ukraine earlier this year, Ukrinform reports.

"After consultations with Prime Minister Donald Tusk, acting out of responsibility to the public and in accordance with the law, I have ordered the declassification of information on all military aid deliveries to Ukraine in 2022-2026," Kosiniak-Kamysz wrote.

According to him, the process of transferring military equipment to Ukraine began under the government of the Law and Justice (PiS) party, when Mariusz Blaszczak served as defense minister. He stressed that the Polish president is informed about every such delivery – currently Karol Nawrocki, and previously Andrzej Duda.

Kosiniak-Kamysz also said he had instructed the country's Military Counterintelligence Service to investigate "who deliberately sought to disclose state secrets."
