New Delhi: January 2, 2017. (Reuters) India's top court on Monday prohibited politicians from using religion and caste to garner votes, a verdict that could force political parties to change their strategy in upcoming elections. "No politician can seek vote in the name of caste, creed or religion," said Chief Justice T.S. Thakur in an order, adding that election process must be a "secular exercise". India is officially secular but political parties have traditionally used religion and caste as the main criteria to select candidates and to appeal to voters. Prime Minister Narendra Modi's ruling Bharatiya Janata Party (BJP) has for years fought elections on a Hindu nationalist agenda, with party members in the past being accused of making anti-Muslim statements to polarize Hindu voters. The court ruling comes just weeks ahead of a state election in Uttar Pradesh, India's most populous state where the two issues of religion and caste generally dominate campaigns.
