Cases checked to exist. Read the judgment before quoting a holding.

Every case cited here has been checked to exist — the citation resolves and names the right parties. The propositions attributed to each case have not been verified line by line against the judgment. Case names link through to the full judgment: read it before quoting a holding in an examination answer, and never carry a proposition from notes into court on trust.

The examinable core. Definition, kinds, functions, merits and demerits. This is one of the most often set topics: “Define political parties. Explain its kinds, merits and demerits” was a 16-mark question in both June 2025 and January 2026; “kinds and functions of political parties” (January 2026), “merits and demerits of political parties” (June 2025) and “multi-party system” (January 2026) appeared in the 80-mark paper.

1. Meaning and definitions

A political party is an organised group of people who share broadly the same political principles and seek to win control of government by constitutional means, chiefly elections, in order to put those principles into effect.

Essentials: organisation and leadership; agreement on fundamental principles; the aim of capturing power; constitutional (peaceful) methods; and a national, not merely sectional, outlook. The last two distinguish a party from a revolutionary movement and from a pressure group.

2. Formation and manifestos

Parties form around several bases, often in combination: ideology and economic interest (socialist and liberal parties, labour and business); religion (Christian Democrats in Germany and Italy); region and language (regional parties in India, the Scottish National Party); caste and community; and the personality of a leader. Some writers also trace parties to human temperament: the conservative who prefers what exists, the radical who wants change.

Before an election a party issues a manifesto, a public statement of its programme and promises. It informs the voter, binds the party to a programme, and forms the basis of a mandate. In Britain the Salisbury convention gives manifesto bills special protection in the House of Lords. In India the Election Commission's Model Code of Conduct includes guidelines on manifestos.

3. Functions

  1. Formulating policies and programmes and putting them before the electorate.
  2. Contesting elections: selecting candidates and running campaigns.
  3. Forming the government: the majority party or coalition governs; in a parliamentary system party discipline keeps the government in office.
  4. Acting as the Opposition: criticising and checking the government and offering an alternative.
  5. Political education and the formation of public opinion.
  6. Linking people and government: conveying grievances upward and explaining policy downward.
  7. Aggregating interests (Almond): combining the demands of many groups into a general programme.
  8. Recruiting and training leaders.
  9. Making the constitution work: the American separation of powers is bridged by party; parliamentary government depends on it.

4. Merits and demerits of parties

Merits: democracy on a large scale is impossible without parties; they make elections meaningful by offering clear choices; they give stable government; they provide an Opposition; they educate the voter; they bring individual and group interests into a national programme. Bryce: parties are inevitable; no one has shown how representative government could be worked without them.

Demerits: they divide the nation and encourage factionalism (Washington's Farewell Address warned of “the baneful effects of the spirit of party”); party loyalty overrides conscience and the national interest; they suppress individual thinking; they spread false propaganda; they use money and muscle in elections; and they foster the spoils system. Robert Michels (Political Parties, 1911) argued that every party, however democratic, falls under the control of a small leadership, the “iron law of oligarchy”.

5. Kinds of party systems

Parties may be classified by ideology (reactionary, conservative, liberal, radical) or by the number that compete effectively for power.

Single-party system

Only one party is allowed: the Communist Party of the former USSR, the Communist Party of China, the Fascist party in Italy and the Nazi party in Germany. Merits: unity, discipline, quick decisions and long-range planning. Demerits: it is the negation of democracy; no Opposition, no free elections, no choice; it leads to dictatorship and suppression of liberty.

Two-party system

Two major parties alternate in power, though minor parties exist: Conservatives and Labour in Britain, Democrats and Republicans in the USA. Maurice Duverger linked the two-party system to the single-member plurality (first-past-the-post) electoral system, an association called Duverger's law. Merits: stable government with a clear majority; clear responsibility; a strong Opposition ready to govern; easy choice for the voter. Demerits: cabinet dictatorship; the voter's choice is limited to two; minority opinions go unrepresented; the two parties may differ little.

Multi-party system

Several parties compete, none usually winning a majority, so that governments are coalitions: France (especially under the Third and Fourth Republics), Italy, Switzerland, Israel, the Netherlands and India. It is associated with proportional representation. Merits: a wide range of opinion is represented; the voter has more choice; minorities and regions get a voice; government by consensus. Demerits: unstable coalitions (the Fourth Republic had more than twenty governments in twelve years); weak and indecisive government; small parties exercise disproportionate bargaining power; responsibility is blurred.

6. The Indian scenario: a brief reference

“Kinds” means party systems. When a question asks for the kinds of political parties, the examiner expects single, two and multi-party systems with examples and the merits and defects of each. A list of party ideologies alone will not do.

How this is examined

The standard 16-mark question (definition, kinds, merits and demerits) needs Burke and one other definition, the essentials, then the three systems with examples and merits and defects of each, and the merits and demerits of parties in general. Close with a paragraph on India. The 6-mark note on the multi-party system is the third of the three systems with French and Indian examples.
