Since 1950, every constituency has been represented by a single Member of Parliament. There remains a technical distinction between
county and
borough constituencies; its only effects are on the amount of money candidates are allowed to spend during campaigns and the rank of the local authority co-opted Returning Officer who presides over the count. Geographic boundaries are determined by four permanent and independent
Boundary Commissions, one each for England, Wales, Scotland, and
Northern Ireland. The commissions conduct general reviews of electoral boundaries once every 8 to 12 years, and interim reviews. In drawing boundaries, they are required to prefer local government boundaries, but may deviate from these to prevent great disparities in electorate; such disparities are given the formal term
malapportionment. The proposals of the Boundary Commissions are subject to parliamentary approval, but may not be amended. After their next Periodic Reviews, the Boundary Commissions will be absorbed into the
Electoral Commission, which was established in 2000. As of 2024, the UK is divided into
650 constituencies, with 543 in England, 32 in Wales, 57 in Scotland, and 18 in Northern Ireland. There are no seats allocated to the fourteen
British Overseas Territories or the three
Crown Dependencies, and there is mixed opinion from the local territorial governments about representation in Westminster from the local governments.
General elections occur whenever
Parliament is dissolved, an action which is part of the
royal prerogative. By
convention the timing of the dissolution is chosen by the Prime Minister (see
relationship with the Government above). Under the
Dissolution and Calling of Parliament Act 2022, if no early election is called, dissolution is automatic on the fifth year after its first meeting day. A candidate for a seat must submit nomination papers signed by ten registered voters from that area, and pay £500, which is refunded if the candidate wins at least five per cent of the vote. Such a
deposit seeks to discourage frivolity and very long ballot papers which would cause
vote splitting (and arguably voter confusion). Each constituency is also called a seat (as it was
in 1885), as it returns one member, using the
first-past-the-post electoral system, under which the candidate with a
plurality of votes wins, that is greatest number of votes. Minors (that is, anyone under the age of 18), members of the House of Lords, and prisoners are not qualified to become members of the House of Commons. To vote, one must be a UK resident and a citizen of either Britain, a
British overseas territory,
Ireland, or a member of the
Commonwealth of Nations. British citizens living abroad are allowed to vote for 15 years after leaving. It is a criminal offence for a person to vote in the ballot of more than one seat which is vacant at any election. This has not always been the case: before 1948
plural voting was permitted as voters qualified by home ownership or residence and could vote under both entitlements simultaneously, as well as for a
university constituency if a university graduate. Once elected, Members of Parliament normally continue to serve until the next dissolution of Parliament. But if a member dies or ceases to be qualified (see
qualifications below), their seat falls vacant. It is also possible for the House of Commons to expel a member, a power exercised only in cases of serious misconduct or criminal activity. In each case, the vacancy is filled by a
by-election in the constituency, with the same electoral system as in general elections. The term "Member of Parliament" by modern convention means a member of the House of Commons. These members may, and almost invariably do, use the
post-nominal letters "MP". The annual salary of each member is £86,584 effective from 1 April 2023. Members may also receive additional salaries for other offices they hold (for instance, the Speakership). Most members also claim for various office expenses (staff costs, postage, travelling, etc.) and, in the case of members for seats outside London, for the costs of maintaining a home in the capital.
Qualifications }} There are numerous qualifications that apply to Members of Parliament. One must be aged at least 18 (the minimum age was 21 until s.17 of the
Electoral Administration Act 2006 came into force), and must be a citizen of the United Kingdom, of a British overseas territory, of the
Republic of Ireland, or of a member state of the
Commonwealth of Nations. These restrictions were introduced by the
British Nationality Act 1981, but were previously far more stringent: under the
Act of Settlement 1701, only natural-born subjects were qualified. Members of the House of Lords may not serve in the House of Commons, or even vote in parliamentary elections; however, they are permitted to sit in the chamber during debates (unlike the King, who cannot enter the chamber). A person may not sit in the Commons if they are the subject of a
Bankruptcy Restrictions Order (applicable in England and Wales only), or if they are adjudged bankrupt (in Northern Ireland), or if their estate is
sequestered (in Scotland). Previously, MPs detained under the
Mental Health Act 1983 for six months or more would have their seat vacated if two specialists reported to the Speaker that the member was suffering from a mental disorder. However, this disqualification was removed by the
Mental Health (Discrimination) Act 2013. There also exists a
common law precedent from the 18th century that the
deaf-mute are ineligible to sit in the Lower House; this precedent, however, has not been tested in recent years. Anyone found guilty of
high treason may not sit in Parliament until she or he has either completed the term of imprisonment or received a full pardon from the Crown. Moreover, anyone serving a prison sentence of one year or more is ineligible, per
Representation of the People Act 1981. Finally, members of the
Senedd (Welsh Parliament) and
Northern Ireland Assembly are disqualified since 2014. Article 159, Section 2 of the
Representation of the People Act 1983 formerly disqualified for ten years those found guilty of certain election-related offences, until this section was repealed in 2001. Several other disqualifications are codified in the
House of Commons Disqualification Act 1975: holders of high
judicial offices, civil servants, members of the regular armed forces, members of foreign legislatures (excluding the Republic of Ireland and Commonwealth countries), and holders of several Crown offices. Ministers, even though they are paid officers of the Crown, are not disqualified. The rule that precludes certain Crown officers from serving in the House of Commons is used to circumvent a resolution adopted by the House of Commons in 1623, under which members are not permitted to resign their seats. In practice, however, they always can. Should a member wish to
resign from the Commons, she or he may request appointment to one of two ceremonial Crown offices: that of
Crown Steward and Bailiff of the Chiltern Hundreds, or that of
Crown Steward and Bailiff of the Manor of Northstead. These offices are
sinecures (that is, they involve no actual duties); they are retained solely to permit the "resignation" of members of the House of Commons. The
Chancellor of the Exchequer is responsible for making the appointment, and, by convention, never refuses to do so when asked by a member who desires to leave the House of Commons.
Officers At the beginning of each new parliamentary term, the House of Commons elects one of its members as a presiding officer, known as the Speaker. If the incumbent Speaker seeks a new term, then the house may re-elect them merely by passing a motion; otherwise, a secret ballot is held. A Speaker-elect cannot take office until they have been approved by the Sovereign; the granting of the royal approbation, however, is a formality. The Speaker is assisted by three Deputy Speakers, the most senior of whom holds the title of Chairman of Ways and Means. The two other Deputy Speakers are known as the First and Second Deputy Chairman of Ways and Means. These titles derive from the Committee of Ways and Means, a body over which the chairman once used to preside; even though the committee was abolished in 1967, the traditional titles of the Deputy Speakers are still retained. The Speaker and the Deputy Speakers are always members of the House of Commons. Whilst presiding, the Speaker or Deputy Speaker traditionally wears ceremonial dress. The presiding officer may also wear a wig, but this tradition was abandoned by Speaker
Betty Boothroyd. Her successor,
Michael Martin, also did not wear a wig while in the chamber. His successor,
John Bercow, chose to wear a gown over a lounge suit, a decision that sparked much debate and opposition; he also did not wear a wig, and his successor
Lindsay Hoyle has continued this tradition by not wearing a wig. The Speaker or deputy presides from a chair at the front of the house. This chair was designed by
Augustus Pugin, who initially built a prototype of the chair at
King Edward's School, Birmingham: that chair is called Sapientia (Latin for "wisdom") and is where the chief master sits. The Speaker is also chairman of the
House of Commons Commission, which oversees the running of the house, and controls debates by calling on members to speak. A member who believes that a rule (or Standing Order) has been breached may raise a "point of order", on which the Speaker makes a ruling not subject to any appeal. The Speaker may discipline members who fail to observe the rules of the house. The Speaker also decides which proposed amendments to a motion are to be debated. Thus, the Speaker is far more powerful than their Lords counterpart, the
Lord Speaker, who has no disciplinary powers. Customarily, the Speaker and the deputies are non-partisan; they do not vote (with the notable exception of tied votes, where the Speaker votes in accordance with
Denison's rule), or participate in the affairs of any political party. By convention, a Speaker seeking re-election to parliament is not opposed in their constituency by any of the major parties. The lack of partisanship continues even after the Speaker leaves the House of Commons. The
Clerk of the House of Commons is both the house's chief adviser on matters of procedure and chief executive of the House of Commons. They are a permanent official, not a member of the house itself. The Clerk advises the Speaker on the rules and procedure of the house, signs orders and official communications, and signs and endorses bills. The Clerk also chairs the Board of Management, which consists of the heads of the six departments of the house. The Clerk's deputy is known as the Clerk Assistant. Another officer of the house is the
Serjeant-at-arms, whose duties include the maintenance of law, order, and security on the house's premises. The Serjeant-at-Arms carries the
ceremonial mace, a symbol of the authority of the Crown and of the House of Commons, into the house each day before the Speaker, and the mace is laid upon the
table of the house during sittings. The Librarian is head of the
House of Commons Library, the house's research and information arm. ==Procedure==
