Spain’s main business industry group, representing most of the country’s largest firms, lambasted Prime Minister Pedro Sanchez’s plan to grant amnesty to hundreds of Catalan separatists.

The board of the CEOE confederation warned that the amnesty plan undermines separation of powers and legal security, the group said in a statement released jointly Monday with three other business groups. The statement also urged that the principles of equality and social cohesion be made the priority “above all other political or economic interests.”
