In Spain, a president of an Autonomous Community serves as the chief executive officer in each of the seventeen Autonomous communities and in the two Autonomous cities, where they receive the name of "Mayor-Presidents". As such, regional presidents are responsible for implementing regional laws and overseeing the operation of the state executive branch. As regional leaders, governors advance and pursue new and revised policies and programs using a variety of tools, among them executive laws, executive budgets, and legislative proposals.
