Executive Agency

An Executive Agency is a part of a government department that is treated as managerially and budgetarily separate in order to carry out some part of the executive functions of the United Kingdom government, Scottish Executive, Welsh Assembly and Northern Ireland Executive. The political aim underpinning the use of such agencies has been to distance ministers and the policy divisions of their departments from responsibility for day-to-day policy delivery but it is important to understand the fundamental differences between these "machinery of government" devices and both non-ministerial government departments, on the one hand, and non-departmental public bodies (or "quangos"), on the other, each of which enjoy a real legal and constitutional separation from ministerial control.
