The "Double Hat"

The HR/VP Role

The High Representative wears two hats simultaneously — serving both the Council (on CFSP) and the Commission (as VP). This institutional bridge was designed to improve foreign policy coherence but can create tensions between intergovernmental and supranational logics.

AD5 Exam Tip

What the Exam Tests

  • →The EEAS was created by the Treaty of Lisbon (2009), operational from December 2010.
  • →The HR/VP "double hat": simultaneously chairs the Foreign Affairs Council AND is a VP of the Commission.
  • →EU Delegations replaced the old Commission delegations after Lisbon — they represent the entire EU, not just the Commission.
  • →CFSP is intergovernmental (unanimity in the Council) — the EEAS serves this but doesn't override member states' bilateral diplomacy.
  • →Kaja Kallas (Estonia) is HR/VP since December 2024 — first from a CEE/Baltic state.
