The NHS is the largest organization in the country with a staff of nearly 1 000 000 people. It consumes nearly six percent of the gross domestic product. The relationship with Government, which provides virtually all the finance required, is different in England, Scotland, Wales and Northern Ireland and the structures in each of these parts of the United Kingdom are, as a result, also somewhat different. In England, the NHS is divided into fourteen Regions comprising something in excess of one hundred Areas, many of which are further divided into Districts. Regions and Areas are statutory bodies, each with a controlling body of members, whilst Districts are subordinate. Ultimately the various Secretaries of State remain responsible to Parliament for the operation of the National Health Service, although the Officers and Members of each Area Authority are empowered to lay down local policies within nationally or regionally agreed guidelines. The cost of running the Health Service is currently in the region of £7500 million per annum. There are over 5000 hospitals in the United Kingdom.
