Controversies
The authorship of the bombings remains a controversial issue in Spain. Sectors of the Partido Popular (PP) and some of the PP-friendly media outlets (primarily El Mundo and the Cadena COPE radio station) claim that there are inconsistencies and contradictions in the Spanish judicial investigation.
As Spanish and international investigations continue to claim the unlikeliness of ETA's active implication, these claims have shifted from direct accusations involving the Basque terrorist organization to less specific insinuations and general skepticism. Additionally, there is controversy over the events that took place between the bombings and the general elections held three days later.
