This study focuses on Catalan cabinet ministers in democratic Spain with a view to understanding what function they perform in the central government: regional ambassador or state agent? To this end, this analysis draws on a sub-dataset comprised of 22 Catalan cabinet ministers taken from a general pool of 220 cabinet ministers and 371 ministerial appointments from 1977 to 2021. Our findings demonstrate, first, that no Catalan cabinet minister has ever reached the position of Prime Minister and Catalans constitute a kind of ministerial “middle class” occupying intermediate positions in the cabinet. Second, the examination of career paths and publications of Catalan ministers shows that their role varied according to circumstances. Third, in this article we argue that those variations can be best interpreted as a delegation between principal and agent relying on two main variables, namely the type of party they belong to in Catalonia and the parliamentarian majority sustaining the party controlling the Spanish cabinet.
