Gitanas Nauseda, a centre-right independent and political novice, won Lithuania's presidential runoff.
Vowing to build a "welfare state", Nauseda said he would bridge the gap between rich and poor in Lithuania, which is among the most pronounced in the 28-member EU, adding that he would also seek to bring urban and rural Lithuanians closer together.
"All people can live with dignity in this small country," the 55-year-old former bank advisor and economist told reporters as he claimed victory at his campaign headquarters in the capital Vilnius following Sunday's vote.
Nauseda also hinted he wanted to soften Lithuania's often sharp rhetoric towards Russia, but insisted that relations could only be improved if Moscow changes its policy towards Ukraine.
Nauseda scored 65.86 percent of the vote ahead of 32.86 percent for Simonyte based on full official results from all 1972 polling stations.
