Transforming Britain's school

What challenges does Great Britain face as regards education policy? Why are things the way they are? What are the dilemmas? Who participates in the development of education policy? Is political power evenly distributed in this policy area? Are some participants more legitimate or authoritative than others, or is there equality in this area? How can we (in a very preliminary way) characterize the British policy process ? Is it opaque or transparent, inclusive or exclusive, easy to follow or complicated, multi-layered? What adjectives would you use to describe the process and why, what did you read?
How does this illuminate the whole of the British political system,  can we find traces of each element (political culture, actors etc.) in our framework  which add to our overall understanding, or only some of them?
