(MENAFN) President Javier Milei’s ruling La Libertad Avanza party secured a decisive victory in Argentina’s parliamentary elections on Sunday, earning 40.8% of the vote, according to early results with nearly all ballots counted. The Peronist opposition coalition, Fuerza Patria, trailed behind with 24.5%, as reported by election authorities. Milei’s movement achieved success across several key provinces, including Buenos Aires, Córdoba, Santa Fe, and Mendoza.

The nationwide vote marked an important political moment for Argentina, as citizens chose nearly half of the Chamber of Deputies (127 out of 257 seats) and one-third of the Senate (24 out of 72 seats). Observers viewed the elections as a referendum on Milei’s leadership and a test of public confidence in his administration’s reform agenda.

La Libertad Avanza’s strong performance translated into 64 new seats in the lower house, bringing its total representation to 94 legislators starting December 10. Although the party still falls short of a full majority, analysts noted that the gains will allow Milei to protect his policies, uphold presidential vetoes, and resist impeachment attempts from the opposition.

Following the announcement of the results, Milei addressed supporters at his campaign headquarters, declaring, “Today has been a historic day. The Argentine people have left behind decadence and chosen progress. Today we have passed the tipping point. Today begins the construction of a great Argentina.”

He also highlighted the crucial role of the incoming legislature, saying that “the new Congress will be fundamental to ensuring the change of direction” and promised to continue advancing his economic and political reforms. “Over the next two years, we must advance the reformist path we have begun,” Milei stated, noting that his proposed projects aim to “consolidate Argentina's growth and takeoff.” He concluded by affirming, “Starting Dec. 10, we will, without a doubt, have the most reformist Congress in Argentine history.”

Despite the victory, voter participation reached record lows. The National Electoral Chamber reported that less than 68% of registered voters turned out, the lowest level since Argentina’s return to democracy in 1983, despite mandatory voting laws.

The results will considerably strengthen Milei’s hand in the Chamber of Deputies, though the Senate is expected to remain under opposition control.

In a post on Truth Social, U.S. President Donald Trump congratulated Milei on the outcome, writing, “He is doing a wonderful job! Our confidence in him was justified by the people of Argentina.” Trump had previously endorsed Milei and warned that U.S. aid could be reduced if the opposition prevailed, saying, “If he loses, we are not going to be generous with Argentina.”
