A political party is an organized group of people who have the same ideology, or who otherwise have the same political positions, and who field candidates for elections, in an attempt to get them elected and thereby implement the party's agenda.

A political party has three components, :

(i) The Leaders: Who formulate policies and programs of the party and choose candidates for contesting elections.

(ii) The Active Members: Who are involved in different committees of the party and participate directly in their activity.

(iii) The Followers: Who believe in the party’s ideology and support the party by casting their votes in favor of the party at the time of the election.
