(27.1) Main feature of multi-party system (1 mark): In a multi-party system several parties compete for power, and more than two parties have a reasonable chance of coming to power either on their own strength or in alliance with others; it allows a variety of interests and opinions to enjoy political representation. (27.2) One-party system and democracy (1 mark): In a one-party system only one party is allowed to control and run the government, so there is no competition and the citizens have no freedom to choose among various contenders for power. Since a democratic system must allow at least two parties to compete in elections and provide a fair chance for the competing parties to come to power, the one-party system is not a democratic option. (27.3) Characteristics of a coalition government (2 marks): (i) It is formed when no single party is able to secure a clear majority of seats on its own; (ii) Two or more parties come together, often on the basis of a common minimum programme, to form the government; (iii) Ministerial berths, portfolios and power are shared among the alliance partners, and decisions are taken through consultation and consensus; (iv) Such a government accommodates diverse regional, social and ideological interests, though it may be comparatively less stable if partners withdraw support. (India has had coalition governments at the Centre since 1989.)
