"We still believe the block might be formed on the basis of right-wing parties. Of course, it wouldn't be enough, therefore, we would need to look for other candidates, other partners, and the Labour Party or the Social Democrats are among potential partners," he told journalists after casting his vote in Vilnius on Sunday.
Masiulis also said he "sees no chance of cooperating with populist parties, including the Path of Courage party and the Order and Justice Party."
He said he wished all six candidates of the Liberal Movement were elected in single-member constituencies but, he added, four constituencies would be a good result.
The Labour Party won 19.82 percent of the vote in the first round of voting in the multi-member constituency and secured 17 seats in the Seimas, followed by the Social Democrats (18.37 percent and 15 seats), the conservatives (15.08 percent and 13 seats), the Liberal Movement (8.57 percent and 7 seats), the Path of Courage Party (7.99 percent and 7 seats), the Order and Justice Party (7.31 percent and 6 seats), and the Electoral Action of Poles in Lithuania (5.83 percent and 5 mandates).
Lithuanians are voting in the Seimas election run-off on Sunday, with 134 candidates running for parliament in 67 single-member constituencies.
