The European Parliament (EP) announced on Thursday it had created a "committee of enquiry" to look into use of "Pegasus and equivalent surveillance spyware," by member states, an issue which has caused a scandal in Poland.
Donald Tusk, leader of Poland's main opposition grouping, has lashed out at the government for its alleged use of the Pegasus software to spy on government opponents.
At a joint press conference, the signatories from opposition parliamentary groups and caucuses declared support for Paweł Kukiz's candidature as head of the commission.
The head of Poland's National Security Department has said there is no evidence employees of the Supreme Audit Office (NIK) were subject to mass surveillance after NIK told a Monday press conference use of the Pegasus spyware was a "working hypothesis."
Poland's Supreme Audit Office (NIK) has said it was hit by thousands of hacking incidents and was checking whether they were linked to the recent spyware scandal involving the Pegasus system.
Jarosław Kaczyński, the leader of Poland's ruling party Law and Justice (PiS), in an interview with PAP denied accusations made by the opposition that the government had abused a sophisticated spyware system to wiretap people opposing the government.
Roman Giertych, a lawyer who has represented Donald Tusk, a former president of the European Council and Polish prime minister, has told a Senate commission investigating a spyware case that his client was the main target of the surveillance.
A senior Polish security official has responded to fresh allegations that a further two people were victims of hacking with Pegasus spyware, saying that all surveillance operations were carried out in accordance with the law.
Senator Krzysztof Brejza has told a parliamentary body probing a spyware case that his phone had been digitally broken into multiple times when he was running the election campaign of the largest opposition bloc, Civic Platform.
The District Prosecutor's Office in the central Polish town of Ostrów Wielkopolski has launched an investigation into the alleged phone hacking of a senior opposition figure.
