The parliament of the Netherlands as the "Staten-Generaal", literally States-General. It is bicameral, divided in two "Kamers" (Chambers). The First Chamber is also known as the Senate and its members as "senatoren", senators. The Second Chamber, "Tweede Kamer", is the most important one. The important debates take place here. Also, the Second Chamber can edit proposed laws with amendments and it can propose laws itself. The Senate doesn't have these capabilities. Its function is more a technical reviewing of laws. It can only pass a law or reject it. Both chambers are in The Hague which is the seat of parliament but not the official capital of The Netherlands, which is instead Amsterdam.

The members of the 12 provincial parlements elect the senators. The value of a vote of a member of a provincial parlement is relative to the population of the province. Provincial parlements, the States-Provincial, are elected by general elections every four years.

The Welsh Assembly is not empowered to make primary legislation and forms the Welsh Assembly Government, which unusually combines legislative and executive functions. The National Assembly consists of 60 elected members; they use the English title Assembly Member (AM) or the equivalent Welsh Aelod y Cynulliad (AC), the latter primarily used when referring to this role when conversing in the Welsh language, and is infrequently heard within English speaking discussions. It is increasingly common, however, to see the Welsh Assembly Government referred to as "the Welsh Government" and the Welsh Assembly is increasingly referred to as Senedd in Welsh, the same word as is used for the Westminster Parliament.
The Northern Ireland Assembly's 108 members are elected from 18 six-member constituencies on the basis of universal adult suffrage. The constituencies used are the same as those used for elections to the Westminster Parliament. Elected members are known as Members of the Legislative Assembly (MLA). The Assembly has authority to legislate in a field of competences known as "transferred matters". These matters are not enumerated in the Northern Ireland Act 1998. Rather, they include any competence not explicitly retained by the Parliament at Westminster. Uniquely, Assembly legislation is open to judicial review.
Between 1921 and 1973, Northern Ireland was governed by the Parliament of Northern Ireland, a devolved assembly whose members were known as Members of Parliament.

Members of the House of Lords are not MPs but Lords of Parliament, and sit either for life in the case of the Lords Temporal, or so long as they continue to occupy their ecclesiastical positions in the case of the Lords Spiritual. Hereditary peers may no longer pass on their seat and those remaining have been elected by themselves, following the House of Lords Act 1999. Their numbers remain at 92 by top-up voting ("by-election") when a member dies, however Lord Avebury’s House of Lords (Amendment) Bill (HL Bill 51) paves the way for their gradual extinction and this may be enacted before grand constitutional reform occurs. Such major reform is likely to be somewhat prolonged based on the Lords' resistance to suggested proposals in February 2007.
There are several special members of Parliament, including the Prime Minister, other government ministers in the Commons, the Chief Whip of each party, Privy Counsellors, and the Speaker of the House.
A candidate to become a Member of Parliament must be a British or Irish or Commonwealth citizen, must be over 18, and must not be a public official or officeholder, as set out in the schedule to the Electoral Administration Act 2006 http://www.opsi.gov.uk/acts/acts2006/20060022.htm (this was a reduction in the lower age limit, as candidates needed to be 21 until the law came into effect in 2006).
Members of Parliament are technically forbidden to resign their seats (though they are not forbidden from refusing to seek re-election). In order to leave the house between elections voluntarily, they must accept a "paid office under the Crown". Two nominally paid offices – the Chiltern Hundreds and the Manor of Northstead – exist to allow members to resign from the House. For more information, see the article Resignation from the British House of Commons.
