A tax advisor has confessed to issuing false invoices to Acciona from a Pamplona restaurant, stating it was done to 'help' Koldo García, and expressed regret for his actions.

The Guardia Civil's UCO unit claims that Koldo García, former advisor to Ábalos, 'availed himself' of former Adif head Pardo de Vera to rig contracts, and that García 'conveyed issues related to the fulfillment' of these contracts.
