Plans to extend charges on migrants and short term visitors using the NHS is "impractical, uneconomic and inefficient", according to the British Medical Association (BMA).
Chair of the trade union, Dr Mark Porter, warned the NHS did not have the infrastructure or resources to implement the policy.
The BMA believes that anyone accessing NHS services should be eligible to do so, but the Government's plans for extending charging to migrants and short term visitors are impractical, uneconomic and inefficient.
The NHS does not have the infrastructure or resources to administrate a charging system that is not likely to produce enough revenue to cover the cost of setting up its own bureaucracy.
The NHS does not need more administrators - it should be spending its money on caring for patients.
