Northamptonshire Commissioners

I notice that the two Northamptonshire Commissioners are both to be paid by Northants itself, thus adding to the County's woes.  Sajid Javid writes as if they will automatically be more effective in their use of taxpayer money, although I can see no reason why they should be.  It seems to be a deeply entrenched prejudice in central government that it knows how to spend money better than local government does, although I can see no evidence of this.
