The Popular Party has promoted in the Senate a total of six investigation committees in the current legislature, taking advantage of its absolute majority in the Upper House, to which a seventh could now be added on the management of Spanish Radio and Television (RTVE), after the announcement made this Monday by the party.
The future commission on the public corporation would join those already created or underway related to the management of the State Society of Industrial Participations (SEPI), the interruption of the electricity supply due to the blackout of April 28, 2025, the catastrophe caused by the DANA of October 2024, the situation of the railway network after the train accident in Adamuz (Córdoba), the Center for Sociological Research (CIS) and for the so-called 'Koldo case'.
In the case of the commission on SEPI, constituted in February 2026, the PP has already advanced the appearance of the First Vice President of the Government and Minister of Finance, María Jesús Montero, on a calendar that would coincide with the period prior to the Andalusian electoral campaign.
For its part, the commission on the state of the railway network was launched after the accident recorded in Adamuz (Córdoba) last January 18 and foresees the summons of the Minister of Transport, Óscar Puente, of former minister José Luis Ábalos and of former advisor Koldo García, among other officials.
Closed commissions on the blackout and the CIS
Likewise, the Senate recently concluded the work of the investigation committee on the energy blackout of April 2025 after the appearances of the third vice-president of the Government, Sara Aagesen, and of the president of Redeia, Beatriz Corredor, and will soon present their conclusions.
The investigation commission on the Center for Sociological Research (CIS) also concluded its work, which included the appearances of the institution's president, José Féliz Tezanos, and of the Minister of the Presidency, Justice and Relations with the Cortes, Félix Bolaños, among others.
In fact, and following the conclusions of that commission, the PP announced a week ago a lawsuit for possible electoral crime against Tezanos, whom they accuse of using his surveys to "systematically inflate" and "benefit" the PSOE to "alter" the will of the citizens, mobilize the socialist electorate and thereby "influence" the results of the polls.
Investigation into the DANA and development of the 'Koldo case'
The investigation committee on the DANA of October 29, 2024, and the management of the different administrations involved, in which the Government delegate in the Valencian Community, Pilar Bernabé, appeared, does continue to be active. In that committee of the Upper House, the former president of the Generalitat Carlos Mazón has not sat, who did attend the Congress's investigation committee on the floods.
These initiatives are joined by the commission on the ramifications of the so-called 'Koldo case', which accumulates two years of parliamentary work, more than a hundred of those appearing, and successive extensions of the list of those summoned by the Popular Group.
In the framework of this commission, political officials such as the president of the Generalitat, Salvador Illa, the former Secretary of Organization of the PSOE Santos Cerdán, the former socialist militant Paco Salazar, and the former President of the Government José Luis Rodríguez Zapatero have been called to appear at different times coinciding with regional electoral processes.
Lastly, if the announced commission on RTVE were approved in the Plenary of the Upper House, the PP would expand the number of investigations promoted in the Senate during the legislature in a context marked by the use of its absolute majority to promote parliamentary control initiatives on different areas of public management.
