Why political parties are needed in a democratic government :
1. Large scale representative democracy - Modern democracies cover a huge number of people over a large territory. Direct participation is impossible, so representatives must be chosen; parties make this possible.
2. Meaningful choice for voters - Without parties every candidate would be independent. No one would be able to promise any major policy change to the people, and the government would be uncertain about its own policies.
3. Accountability - Without parties, elected representatives would be accountable only to their own constituency and no one would be responsible for how the country is run. Parties make governments answerable as a whole.
4. Gathering different views - Parties gather different views on various issues and present them to the government, thus becoming the agency for aggregating and articulating interests.
5. Stable government and effective opposition - The party or alliance with a majority forms a stable government, while the others provide a check on it as the opposition.
Conclusion : The rise of political parties is directly linked to the emergence of representative democracies. That is why parties are a necessary condition, and not merely a convenient feature, of a democracy.
