Mr Kaminski gave details of what he claimed was inside a file on Mr Walesa, covering the period 1970-6: "Inside the personal file there is an envelope and inside, a hand written commitment to cooperate with the secret police signed 'Lech Walesa - Bolek'," he said. Mr Kaminski said that among the documents in this folder were some "hand-written confirmations of receiving funds", signed with the pseudonym 'Bolek'. "In the work folder... are many reports by a secret informant with the pseudonym 'Bolek' and notes by secret police officers from meetings with the secret informant," the director added.
