Executive Branch

The executive branch is the part of government that enforces or executes the law. In democratic countries, the executive often exercises broad influence over national politics, but its scope of power varies greatly depending on the political context. In separation of powers systems, the executive is subject to checks by the legislature and judiciary, while in parliamentary systems, the executive forms the government and is responsible to the legislature. The head of government in parliamentary systems is often distinct from the head of state, while in presidential systems, the head of government is also the head of state.learn more on wikipedia
