The executive branch is the part of government which executes or enforces the law.
Function
The scope of executive power varies greatly depending on the political context in which it emerges, and it can change over time in a given country. In democratic countries, the executive often exercises broad influence over national politics, though limitations are often applied to the executive.
In
political systems based on the
separation of powers, government
authority is distributed between several branches to prevent power from being concentrated in the hands of a single person or group. To achieve this, each branch is subject to checks by the other two; in general, the role of the
legislature is to pass laws, which are then enforced by the executive, and interpreted by the
judiciary. The executive can also be the source of certain types of law or law-derived rules, such as a
decree or
executive order.

fusion of powers, typically

, the executive forms the government, and its members generally belong to the political party that controls the legislature. Since the executive requires the support and approval of the legislature, the two bodies are "fused" together, rather than being independent. The principle of
parliamentary sovereignty means powers possessed by the executive are solely dependent on those granted by the legislature, which can also subject its actions to judicial review. However, the executive often has wide-ranging powers stemming from the control of the government

Ministers

In
parliamentary systems, the executive is
responsible to the elected legislature, which must maintain the confidence of the legislature or one part of it, if bicameral. In certain circumstances (varying by state), the legislature can express its lack of confidence in the executive, which causes either a change in the governing party or group of parties or a general election. Parliamentary systems have a head of government (who leads the executive, often called
ministers) normally distinct from the head of state (who continues through governmental and electoral changes). In the
Westminster type of parliamentary system, the principle of separation of powers is not as entrenched as in some others. Members of the executive (
ministers), are also members of the legislature, and hence play an important part in both the writing and enforcing of law. In
presidential systems, the directly elected head of government appoints the ministers. The ministers can be directly elected by the voters.
In this context, the executive consists of a leader or leader of an office or multiple offices. Specifically, the top leadership roles of the executive branch may include:
