Colombia Elects Fragmented Congress as Petro’s Pacto Histórico Leads Without a Majority

Overview

• Preliminary tallies show Pacto Histórico winning the largest share of seats in both chambers but short of an absolute majority.
• Centro Democrático finished second across Senate and House, leaving no single party in control and forcing cross-party bargaining.
• Abstention exceeded 50% of the 41.2 million eligible voters, according to official preliminary figures.
• In party primaries, Paloma Valencia won the right’s contest, Claudia López took the center, and Roy Barreras prevailed on the center-left, while Iván Cepeda and Abelardo de la Espriella stayed out and remain in the race.
• Álvaro Uribe did not secure a Senate seat, and President Gustavo Petro questioned the vote‑counting software as the national registrar defended the process’s transparency.
