Conservative political newcomer Ivan Duque has been elected President of Colombia.
Mr Duque won 54 percent of the vote. At a victory rally in the capital Bogota, he pledged to unite the country following a divisive campaign.
Mr Duque said, he will overhaul the agreement that guaranteed the rebels seats in Congress and allowed them to contest elections.
He said, he will impose tougher punishments on crimes committed by the rebels during the brutal five-decade conflict with the government.
His running mate, Marta Lucía Ramirez, will become first female Vice-President of the country.
