INDIA'S opposition parties decided today to jointly contest the 2024 national elections in their bid to unseat Prime Minister Narendra Modi and prevent his Hindu nationalist Bharatiya Janata Party (BJP) from achieving a third straight win.

The 26 opposition parties, including Congress and the Communist Party of India (Marxist), decided to work out seat-sharing arrangements in different states in "a collaborative spirit of give-and-take″ to avoid splitting votes against Mr Modi’s party.

India’s national elections are scheduled to be held around May next year.

Congress party leaders Sonia Gandhi and Rahul Gandhi joined other key opposition leaders, including Sharad Pawar, Arvind Kejriwal, the CPI-M’s Sitaram Yechury and Laloo Yadav at a two-day meeting in Mumbai.

Their goal is to set up a direct fight by putting one contestant against a BJP candidate in each voting district.

The opposition parties formed the Indian National Developmental Inclusive Alliance (Inida) in June and seek to challenging Mr Modi’s party on its economic record, rising unemployment and a host of other domestic problems.

Mallikarjun Kharge, the Congress party president, said that at stake is the future of India’s multiparty democracy and secular foundations that have seen assaults from Mr Modi’s Hindu nationalist government.

“Modi’s government is slowly taking the country toward a dictatorship,” Kharge told reporters after the meeting.

Sambit Patra, a BJP spokesman, slammed the opposition parties’ meeting and said their alliance was only a pretence at unity that will end in conflict during the 2024 elections.

Laloo Yadav, a former Bihar state chief minister, complained that the opposition leaders have been the targets of raids and investigations by federal agencies controlled by Mr Modi’s government.

Over a dozen of these instances have led to defections of opposition leaders to the BJP, which is sometimes followed by dropped charges or pressure otherwise being eased. The BJP denies its involvement in the cases.

Mr Modi’s rule has coincided with rising unemployment, attacks by Hindu nationalists against the country’s minorities, particularly Muslims, and a shrinking space for dissent and free media.

However, some analysts say the opposition’s effort to oust Mr Modi is a difficult task. His party directly controls 10 of the 28 states, is in coalition in four other states, and has more than 55 per cent of Parliament’s lower house 543 seats.

Mr Modi became India’s Prime Minister in 2014 and won a second term for his party in 2019 with an easy victory against a splintered opposition.
