Eligijus Masiulis, the group's leader, met with Butkevičius on Wednesday and told reporters afterwards that Butkevičius gave him an impression of a person flouncing about.
"The candidate for prime minister today seems to be a hostage to the political situation. On the one hand, he has the president's very clear position over the formation of a Cabinet and is constantly urged to distance himself from the Labour Party. On the other hand, the Labour Party is the main coalition partner. Obviously, Butkevičius has to maneuver, and there's so much maneuvering, then there's a lack of clarity, certainty, and security," Masiulis said.
President Dalia Grybauskaitė has on numerous occasions spoken against the Labour Party's involvement in the new government.
According to Masiulis, his group is against the Social Democrats' plans to introduce VAT concessions for meat and hotel services, plans to cut state investments. The liberals also have doubts over the planned minimum wage increase and the impact it might have on the country's economy.
"There's another no less important issue. There are a lot of doubts as to how candidate for prime minister Butkevičius, as the Social Democratic leader, will act in the Labour Party's case," the liberal said.
Masiulis also has doubts whether the new ruling coalition will be able to establish and maintain dialogue with President Dalia Grybauskaitė.
Earlier this week, Lithuanian President Dalia Grybauskaitė nominated Butkevičius for prime minister.
The Seimas will vote on his candidacy on Thursday.
