レフ・ヴァウェンサ
In 2008 two IPN employees, Sławomir Cenckiewicz and Piotr Gontarczyk, published a book, "SB a Lech Wałęsa. Przyczynek do biografii" (The Security Service and Lech Wałęsa: A Contribution to a Biography) which caused a major controversy. The book's premise was that in the 1970s the Solidarity leader and later President of Poland Lech Wałęsa was a secret informant of the Polish communist Security Service.
