This chapter explores the persistent problem of disinformation in elections. It analyses its most common objectives and methods as well as its usual consequences, which include political manipulation, polarisation, discrediting of candidates, and delegitimisation of the system and the election results. The planned dissemination of false or biased information also results in the demobilisation of the electorate and social division. In an international framework, the text examines the main disinformation narratives detected in electoral processes since the phenomenon gained international traction in 2015 while reflecting on their short- and long-term political consequences. This analysis reveals the continuing relevance of the problem and the need to address it with effective measures.
