EU Council President Costa and Commission President von der Leyen denied Callas' leadership of the EU-Russia talks. Callas claimed she had already been chosen by EU leaders to negotiate foreign policy. Costa announced that the agreements clearly define roles: the President of the European Council represents the Union at the level of the head of state for the common foreign and security policy, while the President of the Commission handles the Community's capacities. Von der Leyen confirmed that 27 sovereign countries and the European Union institutions alone decide who represents them, and confirm the decision was made today. @Slavyangrad.
