Colombia’s left also managed to prevail in the House of Representatives. The preliminary vote count from the legislative elections held on Sunday outlines a scenario similar to that of the Senate: the Historic Pact and its allies consolidate themselves as the largest individual force in the chamber, although the overall group of right-wing and center-right parties retains the ability to assemble parliamentary majorities.
The result reflects a fragmented Congress without any absolutely dominant blocs. The political map produced by the ballot boxes once again forces the construction of coalitions either to govern or to block initiatives. Within that unstable balance, the House will operate during the 2026–2030 legislative period, which will begin next July 20, when the 183 representatives elected in these elections take office.
On paper, and as is also the case in the Senate, the House presents two strong blocs: one on the left and another on the right, with a fragmentation of theoretically center-right small parties that, nevertheless, in the event of a progressive government could also align with the left-wing majority, as already happened in 2022, or instead consolidate the options further to the right if that camp manages to prevail in the presidential elections in May and June.

The left also wins in Colombia’s House of Representatives
According to the preliminary count by the National Registry and the early calculations released after the election day, the Historic Pact became the list with the largest individual representation in the House of Representatives. The left-wing coalition won between 40 and 41 seats, consolidating a result that reproduces the trend also recorded in the Senate, where it was likewise the most voted force.
The result confirms that the political bloc that brought Gustavo Petro to the presidency maintains significant support among the legislative electorate, even in a political context more adverse than that of 2022. The governing coalition thus manages to maintain a broad caucus in the lower chamber, with presence in numerous departments and special constituencies.
However, although the Historic Pact leads the list of parties with the largest number of representatives, its parliamentary weight is not enough to control the legislative agenda on its own. As also happens in the Senate, the arithmetic of Congress shows that the sum of right-wing and center-right forces continues to be decisive in defining majorities.
Behind the Historic Pact appears a group of traditional parties —currently in opposition— that retain a significant presence in the House. The Democratic Center (28 seats) ranks among the main caucuses and is one of the parties with the largest representation, closely followed by the Liberal Party (28 seats).
Liberalism achieves a robust caucus, remaining one of the key actors in Congress, while the uribismo of the Democratic Center recovers ground compared with recent electoral cycles and once again consolidates itself as one of the main opposition forces.
They are followed by the Conservative Party (19 seats) and the Party of the U (12 seats). Radical Change (19 seats) suffers a significant setback, as also happened to it in the Senate. These movements, together with the Democratic Center and liberal sectors that do not align with the government, constitute the core of a potential majority that could tilt the legislative balance toward right-wing or center-right positions.

Plurality in the ordinary bloc of 160 seats
To this bloc are added medium-sized or small parties and movements that complete the mosaic of the House. Among them are the Green Alliance (7 seats), the New Liberalism (3 seats), and Colombia Reborn (3 seats), as well as the We Believe movement, led by Medellín’s mayor Federico Gutiérrez, the Independent Social Alliance (ASI), and the Democrat Party of Afro roots, with two seats each.
Finally, Roy Barreras’s party The Force, National Salvation, the organization that supports presidential candidate Abelardo De la Espriella, the Mais party, and Putumayo is also Colombia each secured one seat.
The party diversity is also reflected in the special constituencies, which include representatives of Indigenous communities, Afro-descendants, Colombians living abroad, and the peace constituencies created after the agreement with the FARC, completing the 183 seats that make up the House of Representatives for the 2026–2030 term.
The final result leaves a House where no bloc has automatic control. Although the Historic Pact is the largest caucus, its ability to push reforms will depend on agreements with other sectors, especially with centrist parties or with factions of liberalism.
At the same time, the opposition does not have a homogeneous majority either. Right-wing and center-right forces can numerically surpass the governing bloc if they act in a coordinated manner, but the experience of the Colombian Congress shows that these alliances tend to be variable and depend on each legislative project.
This scenario opens the door to constant negotiations within the Capitol. The intermediate caucuses —such as liberal sectors, regional parties, or minority movements— could become key arbiters in decisive votes.
