can i say that we are now organising quite tightly the business of street collections, and i think if committee are minded to reduce the number of collections that we allow, we should decide that before we come to this meeting, because i think it's very difficult in practical terms to do it at this stage, and therefore i would suggest that we do agree twenty-one, not withstanding what graham said, we can take on board some of what he said, and maybe the month before we are asked to take this decision, we have an item on the agenda where we discuss the principle before we get down to the practicalities.
