The People's Party (PP) released the video across its social media channels, using AI to manipulate the likenesses of several individuals linked to the Socialist party. In the video, an AI-generated version of Begoña Gómez appears to say she received a university post due to her husband's role, while a deepfake of former president Zapatero speaks about hiding jewellery in a safe. Both scenarios nod to separate investigations in which Gómez and Zapatero have denied any wrongdoing.
Óscar López, Spain's digital transformation minister, denounced the video on public broadcaster TVE. 'It's telling people a colossal lie, and for a party to do it on its official accounts seems intolerable to me,' he said, warning that viewers unfamiliar with AI could easily mistake the deepfakes for reality. The video carries a small, nearly transparent note indicating it was AI-generated.
Leire Díez, a former Socialist party member whose likeness appeared in the video, filed a legal challenge on Friday accusing the PP of defamation and digital identity theft and demanding the advert be taken down. However, a majority of nine legal experts consulted by El País concluded the video was likely legal because it was labelled as AI-generated and had a tone of political satire. Íñigo Navarro, a former law dean at Madrid's Comillas Pontifical University, said: 'Given the context, everyone knows those people didn't say those things.'
But criminal law professor Juan Antonio Lascuraín of the Autonomous University of Madrid noted the distinction between legality and ethics. 'It's quite another matter to ask whether it's appropriate, exemplary or ethically and politically correct.' José Javier Olivas, a researcher at Spain's National University for Distance Education, called the video a 'red line' for campaign conduct, adding: 'You're using the images of other people, putting words in their mouths that they're not saying, and this qualifies for disinformation.'
The PP has defended the ad. Borja Sémper told reporters: 'If there had been malicious intent to make people believe that the characters who appear there are real, then we'd have a problem. But everyone can see that this is a way of using digital tools to highlight the hypocrisy in which the Socialist party operates.'
Most polls suggest the PP will win the 29 November election but will need support from the far-right Vox party to govern.
The use of AI in political ads is also a growing issue in the United States ahead of its midterm elections. A report from the Wesleyan Media Project identified more than 200 such ads, the vast majority Republican-linked. Co-director Erika Franklin Fowler noted the trend is accelerating: 'For comparison, we identified less than $50,000 in spending on AI-generated ads in the 2024 cycle.'
