Madrid, May 22 (LaPresse) – The investigation into the rescue of Plus Ultra airline, which has former Spanish Socialist Prime Minister José Luis Rodriguez Zapatero under investigation, is causing strong tensions in Spanish politics. Pedro Sanchez's PSOE allies are demanding an explanation as new details of the investigation emerge every day. The affair dealt a severe blow to the socialists, both because Zapatero continued to be a point of reference for the PSOE and to actively participate in all the latest election campaigns, and because it was the Sanchez executive that gave the green light to 53 million in public aid to the carrier, which, according to investigations, could have been used to launder money from Venezuela. Deputy Prime Minister and Minister of Labor and founder of Sumar, Yolanda Diaz, called for Zapatero to explain, as did parties that voted in favor of Pedro Sanchez's investiture despite not being part of the government, such as ERC and Podemos. The government has tried to defuse tensions, arguing that there is no documentary evidence against Zapatero and that Plus Ultra's rescue was legal. The opposition rode the crisis with Vox calling for a motion of no confidence against Sanchez. The People's Party has currently rejected this option, believing it does not have enough votes in Parliament to succeed, but it has increased pressure on the Socialists, including at the European level. The People's Party called on the European Commission to investigate the public aid granted to the airline and then called the current governor of the Bank of Spain, José Luis Escriva, who was a minister at the time of Plus Ultra's bailout, as well as Zapatero's assistant, María Gertrudis Alcazar, to testify before the Senate Committee of Inquiry into Sepi, Spain's state-owned industrial company.
