As ever, I am grateful to the hon. Gentleman for his gentle rebuke. However, I chose my words carefully. It is almost impossible to give a precise definition of any one federal system. The division of the functions, powers and duties that are transferred upwards and downwards, particularly having regard to the concept of subsidiarity—which we shall discuss later—creates the very confusion and contradiction to which I am referring. The problem was not created by me; it is inherent in the way in which the whole package has been put together.
