Poland's opposition Law and Justice party has called for an emergency meeting of the lower house of parliament to issue a resolution rejecting the findings of the Russian report on the Polish presidential plane crash.
The CIS Interstate Aviation Committee (MAK) released a report on Wednesday into its investigation of the crash in April which killed Polish President Lech Kaczynski and 95 top state officials.
The report said that pilot error was the main cause of the crash, along with the number of mistakes that could have contributed to the disaster, including the crew's decision not to land at another airport despite being informed of unfavorable weather conditions at their destination.
Poland's Aviation Committee Secretary, Tomasz Hypki said the report accurately stated the real causes of the Smolensk disaster.
Other Polish experts agreed with the main findings of the report but said they were dissatisfied with the documents provided by Russia.
"We totally reject the MAK report and consider it unreliable," opposition party member Mariusz Blaszczak said.
A Polish report on the tragedy will be ready in January, Poland's PAP news agency said, citing Interior Minister Jerzy Miller.
Russian Transport Minister Igor Levitin said Russia had handed all the transcripts of the air traffic controllers' conversations to the Polish side immediately after the plane crash.
"Our colleagues said they were going to disclose the air controllers' conversations. The records of these conversations in the air traffic control center were officially given to the Polish side just after the tragedy. There are no secrets being withheld from our Polish colleagues," Levitin said.
