Modi, Congress and the ruling coalition will need to fend off an attempt by the BJP to form the next government.
The BJP and its allies have been seeking a new government to form a coalition to take the reins of the government after the 2019 general elections.
The Congress has said that it will contest from the alliance, but it is not clear if the party would be able to form one of the parties.
Congress has already lost three seats in the Lok Sabha polls, the third-worst tally in history for the party.
The party has failed to form any coalition since 2009.
Congress chief Sonia Gandhi has said she wants to form an alliance with the ruling BJP and has hinted at it in the past.
But she has yet to make a statement in this regard.
