I appreciate that it is quite complicated and there seems to be a problem in co-ordinating the different elements of the European Union's architecture between the ECB, the Parliament, the Commission and so on, and perhaps that explains its complexity. In order to understand it, may I ask the following questions? Is it basically the case that the Parliament writes the rule book, the supervisory mechanism is provided by a smaller group of states, are they the eurozone states?
