A blogger's publication of documents from a probe into a wiretapping scandal that rocked the Polish government in 2014 has been described as 'the biggest leak from an investigation in Polish history.'

Jacek Cichocki, chief of the prime minister's chancellery and a former interior minister told RMF FM on Tuesday morning that the leak is unprecedented.

“I asked the head of the Internal Security Agency for a very urgent analysis of the situation, [to clarify] if information disclosed about [intelligence] officers, including their addresses, their names, threatens the work of the service today,” he said.

Businessman and blogger Zbigniew Stonoga released the material on Monday evening, and the documents consist of case files from the Attorney General's investigation into the illegal wire-tapping of public figures in a Warsaw restaurant.

The initial scandal, which broke in the summer of 2014, saw expletive-laden recordings of figures including then Foreign Minister Radosław Sikorski and then Interior Minister Bartłomiej Sienkiewicz published by the Wprost weekly.

In one recording, Sikorski said that the US-Polish relationship was “worthless” and amounted to Poland giving the US oral sex. He also said that Prime Minister of the UK David Cameron had “f****d up” by trying to veto the last European treaty.

Two businessmen and two restaurant employees were charged as a result of the affair.

Meanwhile, Stonoga has claimed in an interview with Polish Radio that the leak “certainly prevents this matter from being further swept under the carpet.”

He also claimed that many staff in the Attorney General's office are “furious” because they have allegedly not been allowed to work “normally” on the case. (nh)
