The role of political parties are mentioned below: 

i. It makes the working of parliamentary government possible. A parliament consists of the representatives of the people. The political parties organize these representatives on party lines. The electorate chooses their representatives on the basis of their party affiliation. The party which gets the majority of votes forms the government and runs the state and the other parties in the legislature constitute the opposition and try to find fault with the government, thus making it more responsible.

ii. Political Parties formulate public policies. Each political party fights the election to achieve its objectives incorporated in their political manifesto. Soon after the election the majority party forming the government seeks to formulate its policies of administration on the basis of promises made in the election manifesto. These policies are made keeping in mind the interest of general public.

iii. Education: The political parties educate public opinion through their propaganda. They publish newspapers, magazines, journals and other printed literature for popularizing their programmes and politics. Moreover, they have a host of speakers who explain and defend party programmes through Press and Platform.

iv. Link between the Government and the People: The political party belonging to the majority group in the legislature serves to maintain a link between the government and the people. Its rank and file explain and popularize the policies, pursued by the government. The political organization maintains a continuous connection between the elected representatives and thus makes the government really representative.

v. Monitor the Opposing Party in Power. Parties also serve as critical watchdogs for the public. The adversarial relationship between the major parties ensures that the party out of power will keep a close eye on its opponent and notify the public of any wrongdoing or policy misstep.

vi. Political parties provide political stability. The political parties in more than one way unite, simplify and stabilized the political process of the country. The destabilizing forces of localism, regionalism, section, interests and geographical situations are tackled by political parties by making these parts of their party ideology thus pacifying the disintegrating forces and inducing cohesion.
