Surely it is the same surgeons who do both NHS and private operations. So, it is queue jumping, as the time taken for private patients is time taken away from NHS ops.
Franbern, this was my concern, but as others have said, the surgeons that do both private and NHS operations will have employment contracts that stipulate their working hours. The detriment to NHS patients, as I see it, is that the surgeons earn far more privately than they would working overtime for the NHS.
There is another factor in the equation, part of my contract deal at work included private health insurance, that, like my company car, was classed as unearned income and attracted income tax. It has been a regular source of additional income for the taxman.
When we leave the EU you can expect VAT to be slapped on the cost of private medical care. The only reason it isn't so at the moment is because it wouldn't be accepted by other EU member states, particularly those (like France) where healthcare is not centrally provided and payments by patients are much more important.
