The Oleksy tapes are tapes secretly recorded during a 2006 conversation between Józef Oleksy and Aleksander Gudzowaty. In the recordings, former Left Democratic Alliance (SLD) Prime Minister of Poland Józef Oleksy denounces his colleagues, and reveals shady aspects of Polish political life. The recordings were published by Polish media in 2007.
The tapes are considered one of the factors responsible for the decline in popularity of Polish post-communist parties (esp. SLD).
