India: United opposition parties have a uphill task to stop Modi winning a third time

The world’s largest democratic election could also be one of its most consequential.

With a population of over 1.4 billion people and close to 970 million voters, India’s general election pits Prime Minister Narendra Modi against a broad alliance of opposition parties that are struggling to play catch up.

The 73-year-old Modi first swept to power in 2014 on promises of economic development, presenting himself as an outsider cracking down on corruption. Since then, he has fused religion with politics in a formula that has attracted wide support from the country's majority Hindu population.

The six-week-long general election starts on April 19 and results will be announced on June 4. The voters, who comprise over 10 per cent of the world's population, will elect 543 members for the lower house of Parliament for a five-year term.

The polls will be held in seven phases and ballots cast at more than a million polling stations. Each phase will last a single day with several constituencies across multiple states voting that day. The staggered polling allows the government to deploy tens of thousands of troops to prevent violence and transport election officials and voting machines.

India has a first-past-the-post multiparty electoral system in which the candidate who receives the most votes wins. To secure a majority, a party or coalition must breach the mark of 272 seats.

While voters in the United States and elsewhere use paper ballots, India uses electronic voting machines.

Modi’s Bharatiya Janata Party and his main challenger, Rahul Gandhi of the Indian National Congress, represent Parliament’s two largest factions. Several other important regional parties are part of an opposition bloc.

Opposition parties, which have been previously fractured, have united under a front called INDIA, or Indian National Developmental Inclusive Alliance, to deny Modi a third straight election victory.

The alliance has fielded a single primary candidate in most constituencies. But it has been roiled by ideological differences and personality clashes, and has not yet decided on its candidate for prime minister.

Most surveys suggest Modi is likely to win comfortably, especially after he opened a Hindu temple in northern Ayodhya city in January, which fulfilled his party’s long-held Hindu nationalist pledge.

Another victory would cement Modi as one of the country's most popular and important leaders. It would follow a thumping win in 2019, when the BJP clinched an absolute majority by sweeping 303 parliamentary seats. The Congress party managed only 52 seats.
