BOGOTA, Colombia (AP) — A polarized Colombia gave conservative political outsider Abelardo de la Espriella a razor-thin lead in a runoff election that will be challenged in the coming days by the ruling party’s progressive candidate.De la Espriella, a business owner and lawyer who earned U.S. President Donald Trump’s endorsement despite never having run for office, led progressive lawmaker Iván Cepeda taking 49.7% of the votes, with 99.9% of results released by electoral authorities. Cepeda, Petro’s ally, earned 48.7% support. Election officials have not formally announced a winner.A victory by de la Espriella is expected to usher in policies that will reverse the agenda of outgoing President Gustavo Petro, including a controversial plan to hold parallel peace negotiations with illegal armed groups. Petro’s protégé, lawmaker Ivan Cepeda, had pledged to push forward that strategy and other social reforms if he won Sunday’s vote.

The election was colored by people’s fears of a renewed internal conflict.“I will govern for all Colombians,” de la Espriella, nicknamed “The Tiger,” told thousands of supporters as he stood behind bulletproof glass in the northern city of Barranquilla on Sunday night. But his conciliatory tone changed as he spoke.
