The People's Party (PP) in Spain has initiated a Senate investigation into the State Industrial Participation Society (SEPI), a government-owned holding company encompassing several major public enterprises. One of the key figures being summoned to testify is María Jesús Montero, the Deputy Prime Minister and Minister of Finance. This move comes as part of the PP's efforts to probe alleged corruption cases that have surfaced surrounding SEPI, raising concerns over the management and accountability of state-owned companies.
