WARSAW, August 15. /TASS/. Late Polish President Lech Kaczynski, who perished in the April 10, 2010 plane crash near Smolensk shoulders the blame for the disaster, Poland’s former second president, Lech Walesa, commented on his Facebook page.

"The captain (plane’s pilot - TASS) repeatedly asked the president about his decision. The situation on the ground (near Smolensk - TASS) should have been precisely that way. The president should not have allowed the plane to take off, let alone given it permission to land," Walesa said.

"Even here one sees the president’s (Lech Kaczynski’s - TASS) utter negligence. It’s worth finding out who helped the president to make such an irresponsible decision," Walesa quipped.

Local analysts believe that Walesa’s harsh criticism should be regarded as another spark in his conflict with the leader of the ruling Law and Justice party, Jaroslaw Kaczynski, the late president’s twin brother. In recent months, the Law and Justice party has stepped up accusations against Lech Walesa. The PiS alleges that in socialist-era Poland he was a secret agent of the security service operating under the nickname, Bolek.

The Interstate Aviation Committee in 2011 said that the crew’s erroneous decision to make a landing in bad weather was the main cause of the disaster. All 96 people on board the presidential Tupolev-154 liner, died in the crash.
