Some 106 lawmakers voted to accept his resignation, none were against and none abstained.
Vaitekūnas cited his lack of fluency in foreign languages, which had prevented him from attending many important events abroad and meetings with foreign visitors, as the reason for leaving the post.
However, he admitted at Wednesday’s meeting of the Seimas Committee on Culture that his decision to step down was due to the Committee on National Security and Defense's (NSGK) findings in its probe into unlawful influence on political processes.
The business group allegedly sought to gain competitive advantage and influence for its media outlets by maintaining informal contacts with Vaitekūnas and receiving non-public information from him.
Vaitekūnas has dismissed all these allegations as untrue.
The Seimas Committee on Culture did not approve his resignation on Wednesday.
