The politicians presented the name and slogan of the future party at a press conference on Wednesday. The decision had been made to name it "Freedom and Justice" and run for parliament under a slogan "One for all, and all for Lithuania".
"People are true to say that three musketeers have gathered," Zemaitis, leader of the Order and Justice party, told the press conference.
The slogan is similar to the one used by characters in Alexander Duma's Three Musketeers " One for all, all for one".
The politicians plan to establish the new party in May.
On Nov 26, the Order and Justice party, the Lithuanian Freedom Union (Liberals) and the movement "Forward, Lithuania" signed cooperation agreement on the upcoming parliament election that will take place in October.
Led by Zuokas, the Freedom Union and Paulauskas' "Forward, Lithuania" currently have seats in the parliament, and the Order and Justice's political group in the Seimas collapsed after the majority of its members left and formed a new group and are now establishing a new party.
