My other comment is in response to Arnold's point about strangers on the floor. As I recall, Sheila Copps was the first MP to have her child with her on the floor of the House of Commons. The order they used to try to stop it was to say that you shouldn't eat on the floor of the House of Commons, which I thought was a rather obscure way of putting it.
What power do we as PROC have to make changes? What are the limits of our own ability to effect change?
