The judge of the National Court investigating the hydrocarbons case has summoned Marc Pons, from Menorca, and Juan Ignacio Díaz Bidart, former chiefs of staff to ex-ministers Teresa Ribera and Reyes Maroto, respectively, to testify as witnesses on January 28. This is stated in a court order, to which Europa Press had access, from Judge Santiago Pedraz. The judge has also summoned businessman Claudio Rivas, whom investigators consider the alleged leader of the hydrocarbons network linked to the company Villafuel, to appear on the same day as a suspect. Furthermore, the judge summoned businessman Víctor de Aldama again as a defendant on January 29. On January 30, the businesswomen Carmen Pano, who claims to have delivered 90,000 euros at the PSOE headquarters on Ferraz Street, and her daughter, Leonor González, will testify. Judge Pedraz has summoned the Director General of Energy Policy and Mines, Manuel García, and Manuel Salles, a company administrator, to testify as witnesses on the 29th. On the 30th, it will be Álvaro Gallego's turn; he may be linked to €108,500 withdrawn in cash, according to investigators.
