 Senior Conservative ministers said in 2014 that the Health and Social Care Act 2012 was biggest mistake they have made in government and that it undermined public trust of their stewardship of the NHS.In 2016, Jeremy Corbyn repeatedly pledged that the Labour Party would re-establish "a modern health and social care service that is fully publicly provided and fully publicly funded".The reforms introduced by Simon Stevens are regarded as the official abandonment of the policy of competition in the English NHS, the establishment of integrated care systems effectively ending the purchaser-provider split, although there has not yet been any legislative acknowledgment of the change in policy.
