Play Champion

As a result of working with Bridging the Policy Gap and Swansea's Play Stratergy - the next step has been to have a meeting to look at 'Play Champions' and whether or not there is a need for them, and if so, what is the role of the champion?
Would a play champion be someone to be the middle man as a voice for children, to pass their ideas, concerns etc onto the authorities or would it be someone that promotes play and raises awareness of the importance of play? We came up with many ideas of what kind of person a champion would be... but if you have any ideas or suggestions please leave your comments.
