María Jesús Montero, secretary general of PSOE Andalucía and former vice president of the government, will join the leadership of the Socialist Group in the Senate as deputy spokesperson from August 1. The appointment puts her at the center of PSOE’s parliamentary strategy in the upper chamber, following the Andalusian Parliament’s decision to designate her as a senator. The group leadership change and her formal accession to the Senate are separate procedural milestones: Demócrata reported that Montero took up her Senate seat on September 8, after the August 1 effective date for her group role.
Montero’s entry into the Senate leadership follows the regional parliament’s selection of her, Susana Díaz and Juan Espadas as senators during its July 23 session. The selection also included four senators from the PP and two from Vox, reflecting the results of the Andalusian elections held on May 17. Unlike senators elected in general-election constituencies, senators designated by an autonomous community are appointed through its regional legislature. Moncloa Política Española has also identified Montero, Díaz and Espadas as senators appointed by the Andalusian Parliament.
Montero’s new role is tied to her position as PSOE’s deputy secretary general, a post she assumed on January 18, 2025. The Socialist Group’s Senate leadership will include Juan Espadas as spokesperson, Alfonso Gil as secretary general and deputy spokesperson, and six deputy spokespersons: María Jesús Montero, César Mogo, María Fernández, Amparo Estructura, Inma Sánchez and María Teresa Macías. The group’s structure is intended to strengthen PSOE’s presence and coordination in the upper house. Montero’s senior party roles increase her political influence but do not, in themselves, change the statutory powers of a senator.
Montero, Díaz and Espadas are prominent figures in the Andalusian PSOE, with experience in the region’s leadership and opposition. Each has previously run as the party’s candidate for the presidency of the Junta de Andalucía against Juanma Moreno of the PP. Montero completed the formalities to become a senator at the Senate Registry earlier that week. The appointments to the Socialist Group’s leadership take effect on Saturday, August 1, as decided by the group’s leadership.
The appointment drew a response from political opponents. Alicia García, spokesperson for the PP in the Senate, posted a pointed message on X, referring to Montero’s previous government roles and the ongoing Senate investigations into alleged government corruption. García’s remarks reflect the political tensions surrounding Montero’s return to national prominence.
Montero’s move to the Senate leadership follows a period of impressive change for PSOE in Andalucía, where the party has faced electoral setbacks in recent years. Her career has included senior roles in healthcare administration, the Junta de Andalucía, the Ministry of Finance and the Spanish government’s vice presidency. She later left her seat in Congress to enter the Andalusian Parliament and become the Socialist group’s spokesperson. For additional context on Montero’s developing role within PSOE and the Senate, see the analysis of her appointment as deputy spokesperson in this related report.
The Senate’s political importance in Andalucía is also reflected in PSOE’s electoral arrangements with Frente Amplio for the November 29 general election. El Correo Web reported that PSOE would lead Senate lists in all eight Andalusian provinces, while Frente Amplio would take the second position in six, with Sevilla and Huelva as exceptions. In districts where previous results had yielded just one PSOE senator, the agreed list places Frente Amplio second and PSOE third, as Montero explained in remarks reported by Demócrata.
Political confrontation in the Andalusian Parliament has continued alongside Montero’s Senate and party responsibilities. El País reported that on October 22, Vox’s Andalusian vice president, Manuel Gavira, shouted an insult at her during a control session as Junta president Juanma Moreno responded to her question. The incident reflected the contentious political environment around Montero’s roles, without changing the institutional basis of her Senate designation or her appointment to the Socialist Group leadership.
In Spain’s parliamentary system, the Senate is the upper chamber, with members chosen through direct election and by designation from autonomous communities. Group leaders coordinate parliamentary work and help set political priorities; including experienced figures such as Montero also raises PSOE’s visibility and helps coordinate its national and regional activity. The Senate leadership’s composition offers a view of party strategy and internal balance as the political field in Andalucía and across Spain continues to evolve.
