Parties are necessary to represent the people of a country. They help to conduct elections in an organized functioning of the legislature.
A political party is a group of people with a definite agenda and who intend to acquire power in the government. Political parties reflect political divisions in a society; so parties are a part of the society and thus involve Partisanship. A political party has three components: The Leaders, the active members and the keen followers.
Political parties play an important role in making laws for a country. Though laws are debated and passed by the legislature, they go by the direction of the ruling party leader irrespective of personal agenda. Political parties are necessary in a democracy as they unite like-minded people from diverse background. Political parties form a two-way link between government and people bringing them close to each other.
