At the June 1999 European Council meeting in Cologne (Germany), EU heads of state and government agreed that ‘the Union must have the capacity for autonomous action, backed up by credible military forces, the means to decide to use them, and a readiness to do so, in order to respond to international crises without prejudice to actions by NATO.’ The agreement was preceded by a bilateral meeting between then President Jacques Chirac of France and UK Prime Minister Tony Blair in Saint-Malo (France), in December 1998. The resulting declaration indicated for the first time a Franco-British consensus on the evolution of a defence component for the European Union: its wording constituted the basis for the agreement at EU level in Cologne.

The deployable forces would be drawn either from NATO assets [see Berlin Plus] or from a pool of national or multinational contributions by EU Member States. At the Cologne meeting, five principles were also outlined that were deemed essential for the successful creation of the CSDP:
The European Council also anticipated the incorporation of the functions of the WEU into the EU. The Council declaration states that in the event of the EU fulfilling its responsibility in the area of the Petersberg tasks, ‘the WEU as an organisation would have completed its purpose’. At the Cologne meeting, Member States also appointed Javier Solana, from Spain, as High Representative for the Common Foreign and Security Policy (CFSP), a post that had been created by the Treaty of Amsterdam.
