Parliamentary system

A parliamentary system is a system of democratic governance of a state in which the executive branch derives its democratic legitimacy from, and is held accountable to, the legislature (parliament); the executive and legislative branches are thus interconnected. In a parliamentary system, the head of state is normally a different person from the head of government. This is in contrast to a presidential system in a democracy, where the head of state often is also the head of government, and most importantly, the executive branch does not derive its democratic legitimacy from the legislature.

Countries with parliamentary systems may be constitutional monarchies, where a monarch is the ceremonial head of state while the head of government is almost always a member of the legislature (such as the United Kingdom, Sweden and Japan), or parliamentary republics, where a mostly ceremonial president is the head of state while the head of government is regularly from the legislature (such as Ireland, Germany, India and Italy). In a few parliamentary republics, such as Botswana, South Africa and Suriname, as well as German states, the head of government is also head of state, but is elected by and is answerable to the legislature.

Parliament of the United Kingdom

The Parliament of the United Kingdom of Great Britain and Northern Ireland, commonly known as the UK Parliament or the British Parliament, is the supreme legislative body in the United Kingdom, British Crown dependencies and British overseas territories. It alone possesses legislative supremacy and thereby ultimate power over all other political bodies in the UK and its territories. Its head is the Sovereign of the United Kingdom (currently Queen Elizabeth II) and its seat is the Palace of Westminster in Westminster, London.

The parliament is bicameral, consisting of an upper house (the House of Lords) and a lower house (the House of Commons). The Sovereign forms the third component of the legislature (the Queen-in-Parliament). The House of Lords includes two different types of members: the Lords Spiritual, consisting of the most senior bishops of the Church of England, and the Lords Temporal, consisting of members of the peerage and life peers who are appointed by the Sovereign on the advice of the Prime Minister. Prior to the opening of the Supreme Court in October 2009, the House of Lords also performed a judicial role through the Law Lords.

Parliament

In modern politics and history, a parliament is a legislative, elected body of government. Generally a modern parliament has three functions: representing the electorate, making laws, and overseeing the government (i.e., hearings, inquiries).

Although some restrict the use of the word parliament to parliamentary systems, it is also commonly used to describe the legislature in presidential systems (i.e. the French parliament), even where it is not in the official name.

Historically, parliaments included various kinds of deliberative, consultative, and judicial assemblies (i.e. the mediaeval parlements).

Etymology

The term is derived from Anglo-Norman parlement, from the verb parler 'talk'. The meaning evolved over time: originally any discussion, conversation, or negotiation (attested around 1100), through various kinds of deliberative or judicial groups, often summoned by the monarch. By 1400, it had come to mean in Britain specifically the British supreme legislature.
