Indian PM Modi casts his vote as giant election reaches half-way mark

• Modi is seeking a rare, third straight term.
• Hindu nationalist party is pit against two dozen parties' alliance.
• Modi casts his ballot where BJP's Amit Shah is candidate.

AHMEDABAD: Prime Minister Narendra Modi voted early as India held the third phase of a massive general election on Tuesday, and called for a strong turnout although he warned of the scorching summer heat.

The world's most populous nation began voting on April 19 in a seven-phase election in which nearly one billion people are eligible to vote, with ballots set to be counted on June 4.

Modi is seeking a rare, third straight term in a vote which pits his Hindu nationalist Bharatiya Janata Party (BJP) against an alliance of more than two dozen opposition parties. Surveys suggest he will win a comfortable majority.

"I urge all citizens to vote in large numbers and celebrate the festival of democracy... To all those working in the heat, I urge you to take care of your health and drink adequate water," he said shortly after voting in his home state of Gujarat.

Modi cast his ballot in the Gandhinagar constituency where his number two, Home Minister Amit Shah, is the BJP candidate.

Clad in saffron and white, Modi was surrounded by hundreds of supporters and party members, signing autographs and talking to children on the way to the polling booth.

He was received by Shah as people beat drums and rang bells.

Modi's campaign began by showcasing his economic record, welfare measures, national pride and personal popularity.

But it changed tack after the first phase of voting on April 19 and focused more on firing up BJP's Hindu base by attacking rivals as pro-Muslim, even as surveys say jobs and inflation are the main concerns of voters.

In an interview with broadcaster Times Now aired on Monday, Modi said he does not oppose Islam or Muslims and wants the community to think about their future growth as they vote.

Tuesday's polling covers 93 seats in 11 states and territories, with Gujarat and Maharashtra in the west and Karnataka in the south accounting for 50 seats. That would complete voting for 283 of parliament's 543 elected seats.

In the 2019 elections, the BJP won more than 70 of 93 seats up for grabs on Tuesday, but faces tougher contests this time as the main opposition Congress party has gained strength in Karnataka and a regional partner has split in Maharashtra.

Voter turnout of 66.14% and 66.71% respectively in the first two phases has been marginally lower than corresponding phases five years back, with analysts blaming the summer heat and the lack of a single strong issue to motivate voters.

The Election Commission has since stepped up a campaign to encourage people to vote while consulting with weather officials and health and disaster management agencies to deal with the impact of the heat wave on Tuesday's vote.

"Weather conditions are predicted to be within normal ranges," it said in a statement on the eve of the vote, calling on voters to "turn out in greater numbers at polling stations and vote with responsibility and pride".

It is also pushing voter awareness to raise participation through messages and songs during Indian Premier League cricket matches, Facebook alerts, announcements at train stations and on flights, messages on train tickets, milk pouches, at gas stations, and films and songs at cinema theatres, among others.

Music app Spotify has created an "election playlist" to motivate voters, and celebrities are being used to make appeals through radio and TV commercials, it said.
