Alfredo Deluque and Honorio Henríquez are the primary candidates competing for the presidency of the Colombian Senate.

The outcome will determine which political faction controls the legislative agenda for the incoming administration of President-elect Abelardo de la Espriella. Because the Senate president wields significant influence over which bills reach the floor, the contest has become a proxy battle for power between the new executive and established political blocs.

To secure the presidency, a candidate must obtain more than 52 votes [1] from the 66 members of the legislative body [2]. The race is currently split between two distinct power centers. The government-elect of Abelardo de la Espriella supports Alfredo Deluque for the position [3]. Conversely, Honorio Henríquez has the backing of the Centro Democrático party, which is led by former President Álvaro Uribe [4].

Preliminary meetings among the 66 compromisarios were scheduled to begin as early as July 15 [2]. These negotiations, some of which took place at venues such as the Hotel Grand Hyatt in Bogotá, aim to solidify voting blocs before the formal session [5].

The official installation of the new Congress is set for July 20 [6]. This date marks the formal transition of legislative power and the finalization of the leadership vote. The high threshold for victory—requiring a supermajority of the 66 available votes [1, 2]—means that neither candidate can win without building a broad coalition of support across party lines.

Both candidates are maneuvering to align their platforms with the 2026-2030 government goals while maintaining their party bases [5]. The tension remains high as the July 20 deadline approaches, with both camps lobbying for the remaining undecided votes in the Cámara Alta.

“The government-elect of Abelardo de la Espriella supports Alfredo Deluque for the presidency of the Senate.”

The struggle for the Senate presidency is a critical early test for President-elect Abelardo de la Espriella. If Deluque wins, the administration will have a streamlined path to pass its legislative priorities. However, a victory for Henríquez would signal that the Centro Democrático and its allies still hold enough leverage to act as a check on the new executive's power, potentially leading to a period of legislative deadlock or forced compromise.
