The Auditor General has warned that while funding for the NHS is set to deplete over the next three years, the financial pressures facing the health service are due to increase to £1bn.
The latest report by the Wales Audit Office shows that the NHS has met its financial targets for the past year. This, however, is not without help from the Welsh Government. A bailout in the region of £157m was given to support the health service, £24.4m of which was taken from next year's funding.
Huw Vaughan Thomas, the Auditor General, says that by breaking into next year's budget the financial burden felt by health boards over the next two years will intensify. But, he adds, it will also "reinforce the Welsh Government's tougher message about the importance of cost control."
In an attempt to secure the health care service, Mr Thomas says work is underway in a number of areas including reviewing the accounting regime, improving funding opportunities and engaging clinicians in financial decisions.
Mr Thomas concludes that this year's audit proves that the way the system is at the moment is 'simply unaffordable' and changes need to be made.
In response to the report, the Welsh Government says it accepts the recommendations made of which, it says, many are being addressed.
This week, all three opposition parties in the National Assembly united to table a motion of no-confidence in the Health Minister Lesley Griffiths.
