This slightly amended diagram is a great overview of the structure of the NHS as from April 2013.
It is adapted from the brilliant publication produced by the NAPC and United Health "The Essential Guide to GP Commissioning". Though it was published before the "pause" to the health bill and therefore refers to GP commissioning rather than clinical commissioning it is still a fantastic easy-to-read document providing a birds eye view of commissioning.
