The European Union is a supranational polity, and is neither a country nor a federation; but as the EU wields political power it complies with the principle of separation of powers. There are seven institutions of the European Union. In intergovernmental matters, most power is concentrated in the Council of the European Union—giving it the characteristics of a normal international organization. Here, all power at the EU level is in one branch. In the latter there are four main actors. The European Commission acts as an independent executive which is appointed by the Council in conjunction with the European Parliament; but the Commission also has a legislative role as the sole initiator of EU legislation.
