I`d add two more:
1. Increase prison staff and estate.
In order to ensure safety for all those in prison, including prison staff and to enable inmates to have the degree of "freedom" from prison gangs that would allow those with genuine motivation who want to rehabilitate and better themselves a route and space to do just that.
2. Create a National Police Service in England & Wales , along the lines of Police Scotland. As well as enhancing training, logistics, IT, procurement and much more, it would save a huge amount of money wasted daily by the 43 police forces in E & W. The amount of money saved could be used to improve the Prison system as well as enhance CPS and other sectors you mentioned. (wouldn`t need to adversly effect London Waiting btw
)
