Internal disputes within Colombia's Alianza Verde party have led to the threatened expulsion of Senator JP Hernández and a possible party split [1].
This instability threatens the cohesion of one of Colombia's key political movements. If Rep. Catherine Juvinao successfully leads a breakaway faction to form a new party, it could redistribute legislative power and weaken the current Alianza Verde platform [1, 2].
The crisis stems from deep-seated disagreements regarding the party's future direction. Some reports said the friction arose from efforts to reach a programmatic agreement with Iván Cepeda [3]. Other accounts said the turmoil was fueled by political maneuvers, specifically an attempt by Claudia López to seize control of a particular sector of the party, which reportedly damaged the potential for a clean split [2].
Senator Hernández is now at the center of these disciplinary tensions. His continued presence in the party remains uncertain as leadership navigates the internal rift [1]. Meanwhile, Rep. Juvinao is studying the possibility of a formal escission. Such a move would allow her to establish a separate political entity, moving away from the current Alianza Verde structure [1, 2].
These developments reflect a broader struggle for influence within the party. The conflicting narratives regarding whether the crisis is about specific policy alliances or leadership power grabs highlight the fragility of the party's internal consensus [2, 3].
“Senator JP Hernández faces potential expulsion.”
The potential fragmentation of Alianza Verde suggests a shift in the Colombian political landscape. A successful split by Catherine Juvinao would not only reduce the party's seat count in Congress but also create a new political vehicle that could alter coalition dynamics in future legislative cycles.
