why there is need of poltical party

We need political parties on account of the functions they perform:

• They draw together people who have similar political philosophies and ideas.
• In the parliamentary arena, political parties provide the government and opposition
• They also lend organisational support. The party machine, also known as the extra-parliamentary wing of the party, is responsible for organising and financing election campaigns, developing policies and recruiting members.
• They articulate philosophies and develop policies. 
• They are an avenue for community groups to influence the decision-making process.
• They are one of the main avenues for political debate and discussion in the community
