The hybrid role of the High Representative in the security and defence field: more in 10 months than in the 10 years?

Despite a growing “momentum” on European Union (EU) security and defence, there are no academic analyses that aim to systematically assess the role of the High Representative of the Union for Foreign Affairs and Security Policy and Vice President of the European Commission (HR/VP) in these strategic domains. This is surprising given that the HR/VP is one of the central actors in the complex institutional architecture of EU security and defence. To fill this gap in the scholarly literature and to contribute to a more fine-grained analysis of the two post-Lisbon Treaty HR/VPs, the article assesses Ashton and Mogherini’s mandates in these fields. This study is particularly relevant because the HR/VP’s hybrid institutional role may represent a unique analytical angle to investigate a formally intergovernmental sector, strongly shaped also by EU institutions’ authority over defence-industrial policy. Following these considerations, the article looks at how the two HR/VPs managed to navigate both the military and the defence-industrial dimensions of EU security and defence.
