Parliamentary system

This is in contrast to a presidential system, which features a president who is not fully accountable to the legislature, and cannot be replaced by a simple majority vote.

Parliamentary democracy is the dominant form of government in the European Union, Oceania, and throughout the former British Empire, with other users scattered throughout Africa and Asia.

[citation needed] Significant developments Kingdom of Great Britain, in particular in the period 1707 to 1800 and its contemporary, the Parliamentary System in Sweden between 1721 and 1772, and later in Europe and elsewhere in the 19th and 20th centuries, with the expansion of like institutions, and beyond In England, Simon de Montfort is remembered as one of the figures relevant later for convening two famous parliaments.

[7] Later, in the 17th century, the Parliament of England pioneered some of the ideas and systems of liberal democracy culminating in the Glorious Revolution and passage of the Bill of Rights 1689.

By the 19th century, the Great Reform Act 1832 led to parliamentary dominance, with its choice invariably deciding who was prime minister and the complexion of the government.

Many of these countries such as Trinidad and Tobago and Barbados have severed institutional ties to Great Britain by becoming republics with their own ceremonial presidents, but retain the Westminster system of government.

[17] Democracy and parliamentarianism became increasingly prevalent in Europe in the years after World War I, partially imposed by the democratic victors,[how?]

Nineteenth-century urbanisation, the Industrial Revolution and modernism had already made the parliamentarist demands of the Radicals and the emerging movement of social democrats increasingly impossible to ignore; these forces came to dominate many states that transitioned to parliamentarism, particularly in the French Third Republic where the Radical Party and its centre-left allies dominated the government for several decades.

The devolved nations of the United Kingdom are also parliamentary and which, as with the UK Parliament, may hold early elections – this has only occurred with regards to the Northern Ireland Assembly in 2017 and 2022.

A few parliamentary democratic nations such as India, Pakistan and Bangladesh have enacted laws that prohibit floor crossing or switching parties after the election.

All laws are equally unentrenched, wherein judicial review may not outright annul nor amend them, as frequently occurs in other parliamentary systems like Germany.

[34] Parliamentary systems like that found in the United Kingdom are widely considered to be more flexible, allowing a rapid change in legislation and policy as long as there is a stable majority or coalition in parliament, allowing the government to have 'few legal limits on what it can do'[35] When combined with first-past-the-post voting, this system produces the classic "Westminster model" with the twin virtues of strong but responsive party government.

[37] Furthermore, ministers of the U.K. cabinet are subject to weekly Question Periods in which their actions/policies are scrutinised; no such regular check on the government exists in the U.S. system.

[39] Once Orbán's party got two-thirds of the seats in Parliament in a single election, a supermajority large enough to amend the Hungarian constitution, there was no institution that was able to balance the concentration of power.

Safeguards against this situation implementable in both systems include the establishment of an upper house or a requirement for external ratification of constitutional amendments such as a referendum.

[39] The ability for strong parliamentary governments to push legislation through with the ease of fused power systems such as in the United Kingdom, whilst positive in allowing rapid adaptation when necessary e.g. the nationalisation of services during the world wars, in the opinion of some commentators does have its drawbacks.

He states that because "legislators are not compelled to vote against their constituents on matters of local concern, parties can serve as organizational and roll-call cuing vehicles without forcing out dissidents.
