Greater Manchester’s NHS devolution deal, which will see the region’s councils take control of a £6bn health budget, has been welcomed by local MPs, senior councillors and NHS chiefs, but has been met with caution elsewhere. Andy Burnham, the shadow health secretary, said it would create a “two-tier NHS” and warned he would not offer such a deal if he was in power. Clinical Commissioning Group leaders described it as a 'genuine opportunity' to improve healthcare, while two leading proponents of Greater Manchester devolution, Goldman Sachs economist Jim O'Neill and former government policy adviser Phillip Collins, both welcomed the deal. Mr O'Neill, who led a review into the growth of the country's cities calling for Manchester in particular to be first in line for new powers, said it was a “very impressive” deal. Mr Collins said: "This reform offers a complete transformation of the way the state works."
