Explanation:

A Political Party is a group of people who come together to contest elections and hold power in the government. They agree on some policies and programmes for the society with a view to promote the collective good. Parties reflect fundamental political divisions in a society. Thus, a party is known by which part it stands for, which policies it supports and whose interests it upholds. A political party has three components:

The leaders

The active members

The followers
