Abstract How has the topic of representation been studied empirically in Portugal? Which main results have been reached? This chapter focuses on the party-voter linkage and aims at mapping the study of party representation in Portugal. On the one hand, we systematize the most relevant research contributions on the topic; on the other hand, we update and consolidate the findings on the most important trends that have been identified so far. The analysis comprises four main lines of research studies on the subject in Portugal: on political and ideological congruence; on promises fulfilment; on political agendas; and on roles of representation. The general conclusion, aligned with the findings of the international research, is that there is a prevalence of reasonable and quite stable levels of correspondence between parties and electorates.
