(CNN) -- A former guerrilla fighter jailed for 14 years and an ex-president will meet next month in a runoff for the presidency of Uruguay, after neither captured more than 50 percent of the vote in Sunday's election.
Jose Mujica, a former Marxist Tupamaro guerrilla who was the top vote-getter Sunday, will be challenged by Luis Alberto Lacalle, who served as president from 1990-1995. The runoff will be held November 29.
With 60 percent of the vote counted, Mujica was leading Sunday with 47.4 percent of the vote to 29.2 percent for Lacalle, news reports said. Another two candidates trailed with 17.8 percent and 2.5 percent of the vote. Only the top two vote-getters advance to the runoff.
Mujica acknowledged the runoff at a boisterous rally in the capital, Montevideo, telling supporters they would triumph next month.
"We have ahead of us 30 days that are a fight but are not filled with hate for anyone," he said.
Third-place candidate Pedro Bordaberry conceded defeat, saying he called Mujica and Lacalle to congratulate them.
