The Shadow Health Minister, Darren Millar says that the NHS in Wales "is on life support and in desperate need of a cash transfusion."
The Conservative AM says that the situation in A&E units in Wales "cannot continue in the way that it is without lives being lost."
His comments come following an open letter from a number of consultants to the Health Minister warning of a 'meltdown' at A&E units in Wales.
Darren Millar said a push by health boards in Wales to balance their budgets by the end of the financial year was putting added pressure on services.
We know that health boards will have to find tens of millions more in savings over the next 12 months. The way they have been meeting their savings targets to date has been to cut hospital in-patient beds, that's why we have got this crisis in our emergency care.
The budgets that the health service has are inadequate and the Welsh Government.
The Welsh Government needs to look at its spending priorities and its budgets to rejig sure that it gets the resources that it needs.
