Summary

Lithuania allegedly requested Hungary's exclusion from a 2019 NATO meeting over fears it leaked classified information to Moscow, as confirmed by Poland's PM Donald Tusk.

In 2019, Lithuania asked NATO to exclude Hungary from meetings due to fears it was passing classified NATO and EU information to Russia. Poland's Prime Minister Donald Tusk stated that Hungarian officials, including Foreign Minister Péter Szijjártó, had been regularly communicating with Russia's Sergey Lavrov during EU Council meetings, confirming long-held suspicions. Lithuania took special care to prevent Hungarian participation in discussions with sensitive content before the 2023 NATO summit in Vilnius. Hungary denies any wrongdoing, accusing their foreign minister of being wiretapped. This incident highlights ongoing concerns about infiltration and espionage affecting NATO unity and security.
