Political parties are a necessary condition for a democracy

Explanation:
A political party is a fundamental unit of democracy where a group of people comes together to contest elections and hold power to run the government.
Its primary function is to fill political offices and exercise political power.  On the basis of the agenda or policies put forward by political parties, the voters choose their representative from them.
The party plays an important role in making laws for the whole country.
 Those parties that lose in the elections play the role of opposition, by voicing different views and criticizing the government for its wrong policies in the legislative organ.
Parties shape public opinion. Parties help people to provide access to government machinery and welfare schemes.
Without political parties, democracy cannot exist. If we do not have political parties every candidate in the election will be independent.

Final Answer:
Democracy can not exist, without any political parties. As every candidate in the election will be independent. So no one will be able to fulfil any promises to the people and the utility of the government will remain uncertain.
