The BJP-led NDA was ahead with leads in 296 seats and the opposition INDIA bloc not far behind in 227 seats as votes were counted for the Lok Sabha elections on Tuesday, setting the course for a third consecutive term as prime minister for Narendra Modi but with a stronger opposition.

While the BJP was ahead in 236 of 542 seats, the Congress had leads in 97, signalling a dip for the ruling party from the 303 score in 2019 and a spike for the opposition party's 52 from the last election. An election marked by acridity and acrimony could end with the treasury benches in reduced numbers and an opposition with more teeth.
