National Health Service
The NHS is made up of four systems: NHS England, Health and Social Care (Northern Ireland), NHS Scotland and NHS Wales. Each system is run by its government.  NHS England is run by the Department of Health and Social Care. The systems are run in different ways in each country within the United Kingdom. For instance, there are no charges for prescriptions in Scotland or Wales, but there are in England.  It is said to be "the most reorganised health system in western Europe".
