The NHS is currently funded by general taxation and National Insurance contributions, and is being challenged more than ever this winter due to the flu crisis.
It remains the largest and oldest single-payer healthcare system in the world.
Last year the government pledged that the NHS will remain free for patients to use after suggestions there might be changes to the system.
According to the latest figures, NHS England expect to spend £123.7bn on the nation’s health for 2017/18.

But how much have you contributed to the NHS so far? What have you cost them?
A quiz has been created by GoCompare to enable you to calculate just how much of a burden your health has been – or not been – on NHS coffers.
It works this out by totalling up your operations, doctors appointments and visits to A&E.
The amount the NHS has spent on you might be higher than you think.
For example, a kidney transplant costs the health service £17,000, while a liver transplant is worth £70,000.
Of the 842 liver transplants performed between 2014 and 2015, 236 were due to alcohol abuse.
Suffering from a broken arm costs £500, while a pair of crutches sets them back £9.50.
One of the most common operations on the NHS is a hip replacement – 62,000 are carried out each year – with just one costing £8,925.
Treatments on the relatively less costly end of the scale are diabetes treatment at £608.16, a vasectomy at £275, and a chest x-ray at £25.
But it’s not just the treatments themselves that cost the NHS.
A GP appointment sets them back £45, simply calling 999 is £64.59 and and a missed outpatient appointment is £108.
Having a baby is an additional cost – a natural birth is £1985 while a caesarean section is £3781.
The test also works out how much you have contributed to the NHS from your earnings.
For example, if you earn £30,000, you will hand over £1222.23 through taxes to them.
