New research suggests that artificial intelligence (AI) is increasingly being used in parliamentary motions, yet no politicians have openly disclosed its use. Two research teams have developed AI detection tools trained on thousands of political motions from Sweden and the UK. Their findings indicate that AI is being used to help draft these motions, but no members of parliament have acknowledged this. Minerva Suvanto, the lead author of the study and a Ph.D. student at Chalmers University of Technology, explains that AI-generated texts are often well-written and persuasive, which can make it difficult for the authors to detect any errors or inconsistencies. This raises concerns about the spread of misinformation, especially as a recent report by the SOM Institute found that 88% of Swedes are worried about AI-generated false information affecting democratic elections. The European Commission introduced new transparency rules in August 2026, requiring AI-generated content to be clearly labeled. However, the regulations allow for some ambiguity, as they exempt content that is only edited using AI. Suvanto suggests that politicians may need to reconsider how they report AI use to preserve public trust. To identify AI-assisted texts in parliamentary motions, the researchers created custom AI detectors for Swedish and English language texts. They analyzed 1,400 Swedish and 1,400 British motions written between 2014 and 2020, a time before widely used chatbots were available. They used a chatbot to summarize each original motion and generate new versions, which served as training data for the detectors. The method developed by researchers at Chalmers University of Technology uses interpretable AI, meaning users can follow the reasoning behind the AI detector through color-coded text. Mattias Wahde, a professor of applied artificial intelligence, notes that this approach is more sophisticated than simply identifying specific words typically used by AI. When the researchers tested their method on parliamentary motions from 2021, when current AI tools were not available, they found only one error in their assessment. However, when analyzing motions from 2022 to 2026, they observed a marked increase in AI-assisted texts. The use of AI in parliamentary motions was nearly nonexistent during the 2021–2022 parliamentary year but rose to almost one in 10 motions during the 2025–2026 year. No significant differences were found between British and Swedish parliamentarians or between different political parties.
