Parliamentary Speaker Irena Degutienė is also of the opinion that law enforcement and the election panel should look into violations of election procedures.
"Law enforcement institutions and the Central Electoral Commission must evaluate reported violations of the election procedure. They have effective and still unused leverage and measures. All political parties should assume political responsibility for allegedly nontransparent actions of their representatives," Grybauskaitė said.
The Press Service of the President communicated Grybauskaitė's position to BNS.
"In this case, it seems to me that significantly more responsibility falls on the Central Electoral Commission, the Prosecutor General's Office and the police which have launched pre-trial investigations for them to be finished as soon as possible, and the Central Electoral Commission has all instruments to make decisions," Degutienė told BNS.
Earlier on Wednesday, the Committee on National Security and Defense of the Lithuanian Seimas decided to propose discussing election violations at the State Defense Council.
"Incidents of vote buying during the Seimas elections can have serious negative consequences," the committee said.
"Having taken this into account, the committee unanimously agreed to draw the Parliamentary Speaker's attention that such incidents might pose threat to national security, therefore, it is worth discussing the issue at the State Defense Council with the participation of representatives from competent state institutions," the committee said in a statement.
"[It is] a mere call to hold a formal meeting of the State Defense Council and once again hold a meeting with heads of institutions. Perhaps we have other ways to solve the issue and call on the institutions to do their job as soon and qualitatively as possible," Degutienė said.
The Lithuanian police have launched over a dozen of pre-trial investigations into alleged vote buying cases during the first round of Seimas elections.
Zenonas Vaigauskas, chairman of the Central Electoral Commission, has acknowledged that the majority of the cases involve candidates of the Labour Party. He also said at a press conference on Monday that it was too early to say whether the violations could change the election results before the investigations were finished.
