Buenos Aires – A significant political shift has occurred in the Argentine Senate, with the ruling coalition, led by President Javier Milei’s La Libertad Avanza (LLA), successfully maneuvering to remove the Justicialist Party (Kirchnerismo) from key leadership positions. The move, spearheaded by Senate bloc president Patricia Bullrich, has been met with criticism from the opposition, who decry it as an overreach of power.
The changes, finalized during a recent session, saw the Vice Presidency of the Senate shift from Neuquén Senator Silvia Sapag, aligned with Kirchnerismo, to Jujuy Senator Carolina Moisés, representing the Convicción Federal bloc – a group of dialoguing Peronist governors. This marks the first time since the return to democracy that Kirchnerismo holds no representation in the Senate’s primary authorities, a development Bullrich publicly acknowledged with a pointed “Ups” on her X account, according to reports. The move is intended to solidify a majority of 47 senators supporting Milei’s reform agenda.
Consolidating Power: A New Senate Majority
The strategic realignment allows the government to bolster its control within the Senate. The coalition, comprised of LLA, the Unión Cívica Radical (UCR), the PRO, provincial blocs and now legislators from Convicción Federal, has secured a majority of 44 senators, further increased to 47 with the addition of support from Convicción Federal. The vote for authorities concluded with 45 affirmative votes, 24 negative votes, and one abstention. This new configuration brings the government within one vote of the two-thirds majority needed for certain legislative actions.
Bullrich defended the maneuver, stating it was designed to “strengthen a majority of 47 senators” that will back the government’s reformist plans. The shift in power dynamics comes as Milei pushes forward with a series of economic and political reforms, facing resistance from opposition parties. Formoseño Senator José Mayans, representing the Justicialist bloc, denounced the move as an “attack” and accused Bullrich of acting with “arrogance,” as reported by El Intransigente.
Broader Political Context and Recent Accusations
This latest development follows a pattern of assertive moves by Bullrich and the Milei administration. Earlier in January 2026, Bullrich accused Kirchnerismo of obstructing the investigation into the death of prosecutor Alberto Nisman, who was investigating the 2013 Memorandum of Understanding with Iran. Clarín reported that Bullrich stated, “Argentina deserves to grasp the truth,” and her post was subsequently shared by President Milei. Nisman’s death remains a contentious issue in Argentine politics, with accusations of cover-ups and political interference.
Bullrich has a long and varied career in Argentine politics, having held positions under multiple administrations. She previously served as Secretary of Criminal Policy (1999-2000), Minister of Labor (2000-2001), Minister of Security under Mauricio Macri (2015-2019), and again as Minister of Security under Javier Milei since 2023, according to Perfil. Her recent actions, including the Senate maneuver and the accusations regarding the Nisman case, demonstrate a willingness to confront the opposition directly.
The government’s actions in the Senate are also occurring alongside debates over labor reforms. Bullrich recently criticized the opposition for their response to the approval of the Labor Reform in the Chamber of Deputies, stating, “They are used to lying. Try to talk about reality and not the fiction you create,” as reported by Perfil. She further asserted that Argentina needs to grow and that the opposition should stop attempting to overthrow governments.
The political landscape in Argentina remains highly polarized, and these recent developments are likely to further intensify the conflict between the ruling coalition and the opposition. The coming weeks will be crucial as the government seeks to implement its reform agenda and the opposition attempts to challenge its authority.
What remains to be seen is how the opposition will respond to this shift in power within the Senate and whether they will be able to effectively counter the government’s legislative initiatives. The dynamic between the government and the Convicción Federal bloc will also be a key factor in determining the success of Milei’s agenda.
