There are three types of party system existed all over the world. (i) One-party system – There is no choice or competition in this system. The party nominate the candidate and the voters have two choices – Either not to vote or write Yes or No to the candidate. This kind of system existed in communist countries or in authoritarian regimes. Example – China, North Korea and Cuba. Supporters of one-party system claim that this system helps the government in mobilising the talents of all citizens towards a common goal. (ii) Two-party system – In this case, two parties are dominated in the system. The winner required maximum number of vote. The smaller party usually merge with bigger one or drop out from the competition. Example – Great Britain and Canada. Supporters of this system believe that this system help the Government to go smooth, it also prevents danger of fragmentation. (iii) Multi-party system – In this system, three or more parties are in the competition to gain control of the government separately or in coalition. When not any single party gain majority votes then several parties join and form a coalition government. Example-India.Supporters of this system point out that it allows more points of view to be presented in the government.
