Political parties are an inevitable part of a democratic system. They contest elections to win votes and power by mobilizing support and floating candidates. Key activities of political parties include preparing candidate lists, publishing manifestos, campaigning through posters, meetings and processions. Major political parties in India are the Indian National Congress, Bharatiya Janata Party, Communist Party of India (Marxist), Bahujan Samaj Party and Nationalist Congress Party. Proper election procedures include preparing voter lists and designating polling stations.
