"The no-confidence issue will be proposed in the first days of the fall session. The ruling coalition and the Social Democrats could have been more resolute in this respect. The good name of the Seimas and the rest of the political system does not benefit from the fact that one of the key posts in parliament is held by a person who has been found guilty in a large-scale corruption case by a court of first instance," Kubilius said in an interview to Lietuvos Žinios daily.
The parliament's fall session is to open on September 10.
Gapšys, parliament's first vice-speaker and the leader of the Labor Party (Laborists), has been found guilty of fraud and black bookkeeping.
He has been imposed a fine of 35,750 litas (EUR 10,400)
An appeal against the verdict has been filed with the Court of Appeals.
