A parliamentary system is a form of democratic governance in which the executive branch derives its legitimacy from, and is held accountable to, the legislature (parliament). In such systems, the head of government (often referred to as the prime minister) is typically a member of the legislature and is chosen by a vote of the legislature or its members. This is in contrast to a presidential system, where the executive is separately elected and independent of the legislature. The parliamentary system is prevalent in many countries, including the United Kingdom, Canada, India, and Germany. The Hebrew translation for "parliamentary system" is מערכת פרלמנטרית (mishpat parlamntari). In other languages, it is known as Sistema parlamentario in Spanish, Système parlementaire in French, and Parlamentssystem in German. Key contextual information includes the principle of collective responsibility, where the executive branch must maintain the confidence of the legislature to stay in power, and the fusion of powers, where the executive is drawn from the legislature.
