3.1.2.2 Electoral systems Flashcards
what is an election
An election is a competitive process in which a designated group of people, known as the electorate, select individuals to serve in specified positions. Elections to public office are a central feature of the democratic process. Members of legislatures, and members of the executive in presidential systems, are chosen and held accountable through elections. Voting in an election is the main form of political activity for many people. For UK general elections, the electorate consists of almost all of the adult population.
Functions of elections in the UK
- Representation
- Choosing a government
- Participation
- Influnece over Policy
- Accountability
- Citizen education
- Legitimacy
- Elite recruitment
Representation
In a representative democracy, elections enable a
large group (the electorate) to select a smaller group (representatives) to act on their behalf.
Choosing a government
General elections determine the composition of the House of Commons, but as the majority party in parliament forms the government, elections also normally determine which party takes power.
Participation
Voting is the key act of political participation for most
citizens.
Influence over policy
Elections allow citizens to voice their policy
preferences. Political parties issue manifestos outlining the policies they would introduce in government. The victorious party then claims a mandate to deliver those policies.
Accountability
The government and individual MPs are held accountable and will be removed from power if the electorate is unhappy with their record.
Citizen education
Election campaigns provide citizens with information on major political issues and the policies of the main parties. In theory, this enables citizens to make an informed decision on how to vote, but in practice the information provided is imperfect.
Legitimacy
Elections give legitimacy to the winning party and to the political system as a whole. By voting, even for a losing party, citizens give their consent to the system.
Elite recruitment
Political parties nominate candidates for election and provide them with campaign resources — and, in return, expect loyalty from them if they become MPs.
Legitimacy
Rightfulness: a political system is legitimate when it is based on the consent of the people. Political actions are also legitimate if they follow from agreed laws and procedures.
Mandate
An authoritative instruction; the doctrine of the mandate gives the party that wins a general election the authority to implement its manifesto commitments.
Manifesto
A document in which a political party sets out its policy programme at an election
In a liberal democracy what should elections be
competitve, free and fair
what does a competitive election require
A competitive election requires that voters have a meaningful choice between different political parties. Free elections require basic civil liberties such as freedom of speech and association, the right to join and stand for a party of one’s choice, and a free press.
key criteria for a fair election
The maxim ‘one person, one vote, one value’ is a key criterion for a fair election: each citizen should have one vote that is worth the same as everyone else’s. Electoral law should be free from bias and overseen by an impartial judiciary.
What should the electoral system do
translate votes cast into seats won in the legislature in a reasonably accurate manner, but as we will see, the first-past-the-post electoral system used in the UK falls short on some of these criteria: not all votes are of equal value, and election outcomes are disproportional.
democractic theorists view
The former prioritise the role of the people in the political process. They focus on bottom-up functions such as policy influence, participation and accountability. In a representative democracy, the government should act in accordance with the wishes of the people.
elite theorists view
elections provide authority and stability for the political system, allowing elites to get on with the task of governing, with only limited recourse to the expressed wishes of the people. They highlight top-down functions such as legitimacy and elite recruitment. In a representative democracy, the political elite decides what is in the best interests of the people.
Different elections in the UK
- General Elections
- Elections to the devloved assemblies
- Local elections
- European parliament elections
- By-elections
General elections
hese elect all 650 MPs who make up the House
of Commons. The Fixed-term Parliaments Act 2011 introduced fixed 5-year terms for governments. Before 2011, the prime minister could call a general election at a time of his or her choosing within their 5-year term. Prime ministers must now seek a two- thirds majority in the Commons if they wish to trigger an early general election.
Elections to the devolved assemblies
Elections to the Scottish Parliament, Welsh Assembly and Northern Ireland Assembly are now held every 5 years.
Local elections
Local councillors are elected for fixed 4-year terms. In some local authorities, all councillors face the electorate at the same time; in others, only a proportion of members (normally a quarter) are elected each year. Some towns and cities also have directly elected mayors. In London, there is an elected mayor and assembly. Police and crime commissioners (PCCs) are also elected in England and Wales.
European Parliament elections
The UK has elected Members of the European Parliament (MEPs) every 5 years since 1979. However, the UK is unlikely to take part in the 2019 elections given the 2016 referendum vote to leave the European Union (EU).
By-Elections
A by-election is held to choose a new representative if a constituency seat in the House of Commons, devolved assembly or English local authority becomes vacant because of the death or resignation of an elected member.
By election
A one-off election that takes place in an individual constituency when a vacancy arises between scheduled elections.
Constituency
A geographical area that elects one or more representatives to a legislative assembly.
Three significant parts of the UK polity are not elected:
- the head of state - the hereditary monarch
- the upper chamber of parliament - the house of lords
- the judiciary
Different electoral systems
- Majoritarian system
- plurality system
- proportional representation
- mixed system
Majoritarain system
The winning candidate must secure an absolute majority of the vote (i.e. 50% + 1 vote). Candidates are usually elected in single-member constituencies. The first-past-the-post system used for UK general elections is often described as a majoritarian system but this is not strictly accurate because the term is being used to reflect the output of the system rather than its mechanics.
Plurality system
First-past-the-post is a single-member plurality system in which the winner needs only a plurality of votes cast (i.e. one more than their closest rival), not an absolute majority. Plurality systems share characteristics of majoritarian systems. MPs are elected in single-member constituencies and both systems are non-proportional.
Majoritarian system definition
An electoral system in which the winning candidate must achieve an absolute majority of votes cast in a single-member constituency.
Single-member plurality system
An electoral system in which the candidate with the most votes in a single-member constituency wins.
Proportional representation
Proportional representation (PR) covers many systems that produce a close fit between votes and seats, although no system can deliver perfect proportionality. The district magnitude (i.e. the number of legislative seats per constituency) is crucial — the larger the constituency, the more proportional the result. PR systems use multi-member constituencies and electoral formulas. Some (e.g. the single transferable vote) allow electors to vote for as many candidates as they wish in order of preference, whereas others (e.g. the closed list system) permit only a single vote.
Mixed system
A mixed system combines elements of the plurality or majoritarian systems with elements of proportional representation (e.g. in the additional member system, AMS). Some representatives are elected in single-member constituencies using first-past-the-post. The remainder are elected by proportional representation in multi-member constituencies — seats are allocated to parties on corrective lines to represent their share of the vote proportionally.
District magnitude
The number of representatives elected from a particular constituency.
Mixed system definition
An electoral system where a proportion of representatives are elected under a majoritarian/plurality system in single-member constituencies, and the others are elected as ‘additional members’ using a proportional system in multi- member constituencies.
Proportional representation definition
An electoral system using multi-member constituencies
in which an electoral formula is used to match the percentage of seats won by each party to the percentage of votes they won.
Majoritarian vs proportional representation
Majoritarian systems:
- A candidate must secure an absolute majority of the vote to win; in a plurality system, they need only win more votes than the second-placed candidate.
- Candidates are elected in single-member constituencies.
- The outcome is not proportional — large parties take a higher proportion of seats than their share of the vote merits, while smaller parties are often under-represented.
- The systems tend to produce single-party governments with working parliamentary majorities.
Proportional representation systems:
- Candidates are elected in multi-member constituencies.
- Electoral formulas are used to allocate seats in the legislative assembly.
- The outcome is proportional — there is a close fit between the share of the vote won by a party and the share of the seats it is allocated.
- The systems tend to produce coalition governments as no single party wins a majority of seats.
When is first-past-the-post used in the UK
General elections
When is supplementary vote used in the UK
Mayor of london, police and crime commissioners
When is regional list used in the UK
European Parliament elections in Great Britain; list seats for the Scottish Parliament, Welsh Assembly and London Assembly
When is single transferrable vote used in the UK
Assembly, local and European Parliament elections in Northern Ireland; local elections in Scotland and Northern Ireland
When is additional member system used in the UK

Key feature of first-past-the-post
Plurality system; single-member constituencies; disproportional outcome
Key feature of supplementary vote
Majoritarian system; used to elect individuals; voters record two preferences; winning candidate has a majority
Key feature of regional list
Proportional representation system; electors vote for a party in multi-member regions; proportional outcome
Key feature of single transferable vote
Proportional representation system; electors rank candidates in multi-member constituencies; proportional outcome
Key feature of additional member system
Mixed electoral system; electors cast two votes — one for
a constituency candidate elected by FPTP and one for a regional list candidate elected by closed list PR; list candidates are allocated to parties on a corrective basis to produce a proportional outcome
How does FPTP operate
- MPs are elected in single-member constituencies. Each constituency in the UK elects one representative to the House of Commons.
- Electors cast a single vote by writing a cross (X) on the ballot paper beside the name of their favoured candidate.
- A candidate requires a plurality of votes to win: that is, one more vote than the second-placed candidate. There is no requirement to obtain a majority of the votes cast. In contests involving three or more candidates, the winner may fall well short of an overall majority. Table 10.2 shows the extreme case of Belfast South in the 2015 general election where the victorious candidate secured fewer than one in four votes - 24.5 % was the winner with the social democrat and labour party
Constituencies
Constituency boundaries are determined by independent boundary commissions which review the size of the electorate in each constituency every 8–12 years. Differences in size are permitted if there are significant geographical factors. The most populous constituency at the 2015 general election, the Isle of Wight, had an electorate five times larger than the smallest constituency, Na h-Eileanan an Iar (the Western Isles) — 109,000 compared to 20,900. Urban constituencies tend to have fewer electors than suburban and rural seats. The geographical size of constituencies also varies. The smallest are inner city seats while the largest are rural seats in Scotland.
What did the conservatives do to the size of constituencies?
The Conservative government confirmed its plans to reduce the number of MPs from 650 to 600 and reduce disparities in constituency size. With the exception of two constituencies in Scotland (Orkney and Shetland, and the Western Isles) and two in England (the Isle of Wight will elect two MPs), all constituencies will have electorates that deviate by no more than five percentage points from the UK average of 74,769.
Safe seats
The competitiveness of elections varies significantly across constituencies. In safe seats, the same party wins at election after election because the incumbent party’s majority is so large. The safest seat in 2015 was Liverpool, Walton, where Steve Rotheram won 81% of the vote
Marginal seats
Marginal seats are the most competitive. Here, the incumbent party has a small majority which their nearest rival(s) has a realistic chance of overturning. Parties focus resources here as the results determine the overall election outcome. Turnout tends to be higher in marginal seats because votes are more likely to make a difference to the result. Gower in Wales was the most marginal constituency in 2015, although this was the first time in a century that Labour did not win the seat. Nuneaton was the first marginal seat to declare its result, with the swing to the Conservatives indicating that they were on course to win most seats.
Safe seat
A constituency in which the incumbent party has a large majority, and which is usually retained by the same political party at election after election.
Marginal seat
A constituency where the incumbent party has a small majority and which may thus be won by a different party at the next election.
Swing
The extent of change in support for one party to support for another party from one election to another.
What was the safest seat in the 2017 general election?
Liverpool Walton - Labour won a 77% majority
What was the most marginal seat in the 2017 general election?
East Dunbartonshire - where the then Liberal Democrat leader Jo Swinson lost the seat to the SNP by 149 votes (0.28%).
Features of the first past the post election
- a two-party system
- a winner’s bonus
- bias to a major party
- discrimination against third and smaller parties
- single-party government
two-party system
FPTP tends to foster a two-party system in which two major parties compete for office (see the case study). It favours major parties that have strong nationwide support, which gives them a good chance of securing a parliamentary majority. There is little incentive for a faction within a major party to split and form a new party because small parties find it very difficult to win seats. The Social Democratic Party (SDP) was formed by disaffected Labour MPs in 1981. It fought the 1983 general election in an Alliance with the Liberals, winning 25% of the vote but only 23 seats. New ‘outsider’ parties also find it difficult to break through. The UK Independence Party (UKIP) won its only seat at a general election in 2015 but this was poor reward for 12.6% of the national vote.
two party system since 2010
The UK’s two-party system has, however, been in failing health. Increasingly, the UK resembles a multiparty system. In 2010, the Conservatives and Labour together received only 65% of the vote — a postwar low. Although the total rose to 67% in 2015, this was still the second lowest in the postwar period. Support for parties other than the Conservatives, Labour and the Liberal Democrats reached a record 25%.
1955 General election
The 1955 general election was a contest between the incumbent Conservative government and the opposition Labour Party. Both scored more than 46% of the vote, but a 2% swing from Labour to the Conservatives saw the latter gain 23 seats. This gave the Conservatives a parliamentary majority of 60 seats. Voters rewarded the party in office for presiding over a healthy economy and endorsed the prime minister, Sir Anthony Eden, who had become Conservative leader the previous year. Labour’s credibility had been damaged by internal divisions.
Winner’s bonus definition
The share of seats that the first-placed party wins in excess of its share of the vote under FPTP. The system exaggerates the support received by the most popular party, giving it more seats than is proportional to the number of votes it received, thus boosting its majority in parliament.
Winner’s Bonus
FPTP tends to exaggerate the performance of the most popular party, producing a winner’s bonus or landslide effect. A relatively small lead over the second-placed party is often translated into a substantial lead
in parliamentary seats. The Conservatives won landslide victories in 1983 and 1987, with Labour doing likewise in 1997 and 2001
Bias to one major party
Rather than simply favouring the winning party, FPTP is biased towards one of the two major parties. The system favoured Labour from the 1990s until 2010. Between 1997 and 2005, the proportion of seats won by the Conservatives was lower than their share of the vote. Then in 2010, the Conservatives led Labour by 7% but fell 19 seats short of an overall majority.
Number of reasons for Bias
- Tactical voting
- Differences in constituency sizes
- Differential turnout
Tactical voting
Labour benefited from anti-Conservative tactical voting between 1997 and 2005.
