A recording revealed Cerdán's connection to illegal commissions, according to various media reports
The PSOE has immediately denied the information and even Cerdán has said that it is not afraid because it has not participated in any illegal operation.
The recording, to which the UCO unit of the Civil Guard has had access, indicates that the PSOE's Secretary of Organization , Santos Cerdán, was involved in fraud in the award of public works. According to various media reports, in the recording Cerdán is heard talking about the money owed to them by various companies, with former Minister of Transport José Luis Ábalos and his former adviser Koldo García.
The Ser Chain, the eldiario.es portal and the media El Mundo have reported an interview detected in the 'Koldo' case in which Cerdán, Ábalos and García are heard talking about the debt owed to them by four construction companies.
In total, the debt would be around EUR 400 000, according to the researchers, for charging commissions to construction companies in exchange for awarding public works.
