In a society of social media and civic journalism, people have the opportunity to discover as many information from across the globe, thus with the help of their social media accounts, they are able to share and comment particular news they consider relevant. However, with this kind of freedom, media and communications experts pose a concerning question: how to differentiate trustworthy and ethical news from fake news? This paper will present the function of fake news in 2018, specifically how the news sites narod.hr and tportal.hr have written and commented the Istanbul convention: from its preparation for its ratification until its final ratification process in October 2018. In order to analyze with detail the content of the Istanbul convention, the work will foremost focus on the theoretical aspects of propaganda and fake news, covering the definition of propaganda and fake news, the role of fake news in the digital era, thus the core characteristics of both terms. In addition to this, the work will use qualitative and quantitative research, in which the articles will be analyzed with the help of selected variables. Moreover, in order to understand the phenomenon of fake news and media scepticism on ideological subjects such as the Istanbul convention, there are also an in-depth interview included with the editors of the news sites and with Croatian political commentators. One of the issues faced during the research was when conducting in-depth interviews, where some commentators could not meet in person, thus it was difficult to comment or ask additional questions, while some had limited time to fully participate in the interview. All in all, the research shows how the selected sites intensively followed the Istanbul convention, thus the political commentators concluded how each site has its own purpose in writing about the Istanbul convention.
