He also said his party would consider if the Social Democrats invited his party to jointly form a government.
"I consider the president's statement totally rational. We, the Homeland Union, have repeated since the first round of voting in the Seimas elections that responsible political parties should not form a coalition with parties that use dirty methods, including voter bribery and buying votes in prisons. In this respect, to my mind, the president's statement is absolutely logical, rational and it shows a responsible political attitude," Kubilius told journalists on Monday.
The head of the outgoing government also expressed regret that the Social Democrats "failed to make conclusions" after the first round.
According to Kubilius, the Constitution and laws say the president has "a right, obligation, and responsibility to ask someone to form a government", and judging from her Monday's statement, she will approach Social Democratic leader Algirdas Butkevičius with the task.
"If Butkevičius is asked, if Butkevičius starts thinking about who they should talk to, then it will be time for further considerations and answers," Kubilius said.
Following the second round of voting in the Seimas elections, leaders of Lithuania's three opposition parties – Algirdas Butkevičius, leader of the Social Democratic Party of Lithuania, Viktor Uspaskich, leader of the Labour Party, and Rolandas Paksas, leader of the Order and Justice Party – agreed early on Monday on the formation of the ruling majority.
But Lithuania's President Dalia Grybauskaite stated on Monday morning the Labour Party must not participate in the new government.
"In my opinion, forming the government should not involve a party which is suspected of the highest number of gross violations of election procedures, which is suspected of black bookkeeping and leaders of which are charged with fraudulent bookkeeping," Grybauskaitė told journalists after meeting with Butkevičius.
According to preliminary results published by the Central Electoral Commission, the Social Democrats will have the largest group of 38 members in the new 141-seat parliament. The Homeland Union – Lithuanian Christian Democrats should be second with 33 members, followed by the Labour Party with 29.
The Order and Justice party should have 11 seats in the new parliament, the Liberal Movement should have 10, the Electoral Action of Poles in Lithuania should have eight, the Path of Courage should have seven and the Peasants and Greens Union should have one seat.
