As a former shadow Home Secretary—I was also shadow almost everything else without achieving the substance, as the current shadow Home Secretary will find out over long years of opposition—may I make the point to my right hon. Friend that the effectiveness of the machinery of Government depends on whether it works? It has been found in the past—for example, when the Conservative Government took broadcasting away from the Home Office—that the machinery of Government must work. Also, as a former Conservative Home Secretary found, prisons policy can be a mess if it is not properly administered. Does my right hon. Friend therefore agree that the key issue is not the boundaries of Government, but whether the structure works?
