Virtually every Government programme for children and every Government Department in the UK is expected to involve children and young people in its policy development and service delivery (Children and Young People's Unit, 2001). It is the new orthodoxy. Yet, hard questions are often avoided when reciting the mantra of participation. Why bother? What has changed as a result? This paper first seeks to explore the constraints and limitations of this drive in public policy in England. Secondly, by looking at one specific example, it considers elements of practice to enable participation to be effective as a catalyst for change. Third, it proposes a framework that sets out an agenda for social inclusion that is itself influenced by children and young people and not reliant on the changing and often clashing fashions in Government.
