BARRANQUILLA, Colombia: A flamboyant US-backed lawyer who has never held public office narrowly won Colombia's presidential runoff on Sunday (Jun 21), swinging the country hard right with a promise to wage war against drug-running guerrilla groups.With almost all polling centres reporting, Abelardo de la Espriella won 49.66 per cent of the vote versus left-wing Senator Ivan Cepeda's 48.70 per cent.The 47-year-old's victory is set to improve strained relations with Washington and extends a wave of rightist candidates who have swept to power across Latin America promising "iron fist" security policies."We are beginning a new era!" he told supporters in the Caribbean city of Barranquilla from behind bullet-proof glass.Show MoreShow Less"For those who have sown violence, terror, drug trafficking, and corruption all these years, their time is up!" he said.US President Donald Trump and a host of right-wing leaders from across the Americas have clamoured to offer congratulations and support.UNRESTAfter a campaign marred by guerrilla bomb attacks and the murder of a leading conservative presidential candidate, there was a quick sign of how tough it will be to unite the country.As he was speaking, thousands of protestors gathered in Colombia's third-largest city Cali.Some burned American flags, others wielded bricks and bars and clashed with riot police, who tried to disperse the crowd with teargas.But elsewhere there was elation. De la Espriella supporters poured onto the streets of several cities wearing the canary-yellow national football jersey he had adopted as a campaign uniform.They waved flags, blew horns and expressed hope that "The Tiger", as they call him, would bring security."I'm very happy," said 30-year-old supporter Daniela Oliveros in Barranquilla. "I believe a lot in the country, I believe a lot in freedom.""Abelardo, at this moment, is giving us above all a sense of security, employment, and dignity," she said.Demonstrators clash with riot police as they protest the preliminary results of the presidential runoff election in Cali, Colombia, on Jun 21, 2026.

But to win Cepeda would need hundreds of thousands of votes to be overturned.The margin of error for the first count is usually in the low thousands.De la Espriella warned Cepeda to respect the democracy, form the opposition and "don't even think about stoking violence.""The Tiger can still bite you harder than he has bitten you at the ballot box" he warned.Cepeda's campaign had appealed to many worse-off Colombians who wanted a more equal economy and fear a return to violence."I'm very worried about what Abelardo might do in a government," said 40-year-old bank worker Santiago Galindo, who voted for Cepeda.Galindo worried "how far his thirst for power could go and his willingness to trample over people without really caring about them."
