Choosing Health and Social Care locally

So htere's a plan for Local Government to work with NHS to choose services that are right for patients.
Right now, local government chooses how to meet our social care needs (which it does with limited central guidance), and NHS chooses our health needs (with a lot of central guidance in the form of national targets etc). The result - as the budget gets squeezed, each side tries to fob chunks of budget onto the other.
Actually this might just work - single point of commissioning, informed by national expertise (Royal Colleges of health professionals, over-arching national targets for population health, etc)
