According to the data provided by the vote counting panel, Gentvilas was supported by 330 of the 659 votes, while Gailius secured 329 votes.
"The winner cannot turn his back on those who voted differently and thought differently. Therefore, I am not turning my back in light of this minimum advantage, I have no right to be irresponsible," Gentvilas said after the announcement of the results.
He told journalists he had wanted to win and felt well to be the winner, however, said the narrow advantage was a bit alarming.
"I have to feel even more responsibility, as it is clear how a single vote can be decisive. The minimum advantage should better be bigger. It gives me a feeling of uncertainty and a big responsibility," said Gentvilas.
The party, which is faced with corruption suspicions, had to pick a new leader after Vilnius Mayor Remigijus Šimašius resigned from the post in late October.
