The news framing of assisted death in Portugal and the United Kingdom from 2016 to 2024 was analyzed across two dimensions. The first examined the overall frames through source positions and occupations. The second observed argumentative structures by coding argument characteristics: manifestation, origin, level, and evaluation. A total of 7464 structures were identified from 1731 published stories in Expresso, Público, The Guardian, and The Telegraph. The research utilized a methodological framework based on framing theory, creating direct connections between frame analysis and argumentative structures to improve the validity of valence and thematic framing mechanisms. The findings indicated significant differences between countries. The Portuguese news media showed a marked inclination to present concentrated opposing arguments with a higher argumentative density. In contrast, British newspapers displayed a greater diversity of arguments in favor of assisted death, along with a more cohesive representation among pro-assisted death sources. Three distinct argumentative profiles were identified, each showing different divisions between Portugal and the UK. These results reveal that argumentative structures in assisted death coverage reflect deeper systemic values and news media structures, positioning these quality newspapers as influential actors in representing arguments about moral legitimacy around bioethical issues. The study makes a valuable contribution by offering a comprehensive understanding of how these four newspapers frame arguments about assisted death while proposing an innovative analytical model applicable to comparative studies of other news media.
