The fallout from the Health and Social Care Act is now believed to have cost in the region of between £1.5 billion and £1.6 billion. Originally, the reforms were estimated to total between £1.2bn and £1.3bn.
Ironically, the increase comes at a time when the NHS is tasked with making £20bn of efficiency savings.
Health Secretary Jeremy Hunt revealed the additional £300m reform costs in a written statement to the House of Commons.
The Act, which was passed through Parliament in March this year, has been formally opposed by a number of high profile organisations, unions, charities and royal colleges who argued it will increase privatisation within the health service and lower standards of care for patients.
