Critics of the peace deal between the Colombian government and the FARC rebel group were the winners of the Congressional elections.
Ex Colombian President Alvaro Uribe's Democratic Center Party has won numerous seats in the Congressional Elections for the 106 members House of Representatives and 102 seat Senate, but not an overall majority.
The outcome of the lower house and Senate elections and primaries for left and right-wing parties, all held on Sunday, were keenly watched as the deeply polarized Andean country heads towards an election set for May 27.
The Farc, who kept their acronym when they transformed from an insurgency into a political party, took a meagre 0.33% of the vote.
"For many people it is hard to swallow Farc leaders campaigning on the streets", said Kristian Herbolzheimer, a Colombia specialist at Conciliation Resources, a London-based consultancy.
It is significant that in upper house victor has been Democratic center, conservative training of former president Álvaro Uribe, very critical of peace agreement reached with guerrilla.
The hardliners' victory raises questions about the future of the peace agreement signed with President Juan Manuel Santos in November 2016. His own Party of National Unity, which was the biggest political movement in the outgoing congress, finished fifth overall.
Ivan Duque, presidential candidate of the party Centro Democratico, gives a speech after finding out the results of the legislative election in Bogota, Colombia March 11, 2018.
Two candidates under pressure to join forces are Humberto de la Calle, who was the government's chief peace negotiator, and former Gov. Sergio Fajardo.
Colombian left-wingers advocate investment in education, as well as strong support for a recent peace deal with Marxist rebels, to combat profound inequality.
Investors have been uneasy over possibility of Petro, a former member of the disbanded M-19 guerrilla group and ex-mayor of Bogota, winning the presidency as he has been running neck and neck with Duque in opinion polls.
More than 6 million votes were cast in the three-way right-wing primary and 3.5 million in the two-way left-wing contest.
Santos suspended the talks after a three-month bilateral ceasefire expired in early January and the rebels immediately went on the offensive, launching a deadly attack on a police station in northern Colombia.
Duque has said that while he would not "thrash" the peace accord with the rebels, he would attempt to modify certain aspects, like a provision that allows the former rebels with drug-trafficking convictions to participate in politics.
"A true peace is built through the triumph of the rule of law not through the relativization of justice", he told his followers after election results came in. Voters who are critical of the peace deal will be able to choose between Duque and German Vargas Lleras, the conservative leader of the Radical Change party.
