Definition of Political Parties
Political parties are indispensable instruments in a democratic system. They are formed with definite ideologies, and programme of action. They enlighten the general public on issues concerning the society and state and they also prescribe alternatives. Through propaganda they educate people on political issues and garner their support for their policies and programme. In legislative bodies they represent organized opinion of the voters. In parliamentary democracies the party or an alliance of parties can win a majority of seats in legislature and forms the ministry (executive) examples: UK, India. In presidential democracies, the chief executives (president) are elected on party basis (USA, France). In any system political parties function as intermediaries between the government and people.
There is consistent competition between the various political parties and this competition ensures the mature functioning of a democracy.
