MUMBAI: Exit polls have predicted that the Bharatiya Janata Party (BJP) will emerge the largest political group in Maharashtra and Haryana states.

Tens of millions voted in Indian state elections Wednesday in the first major test of Prime Minister Narendra Modi’s popularity since he stormed to power in May on a pledge to reform the economy.

Modi has campaigned extensively, particularly in Maharashtra, aware that an endorsement in state polls and especially in India’s financial capital could help him push through his promised economic reforms.

“Urging the people of Haryana & Maharashtra to go out & cast their votes. Youngsters must show the way & ensure record turnout,” Modi tweeted early Wednesday.

The BJP is expected to benefit from anger and fatigue toward the Congress Party, which was kicked out of central government in May and has held power in Maharashtra for 15 years and in Haryana for a decade. The BJP has taken a gamble on its popularity and is campaigning alone in both states after severing ties with its allies, including the far-right Shiv Sena, its partner in Maharashtra for 25 years.

Modi came to power promising to wipe out widespread corruption and revive the flagging economy, but he is yet to bring in much-needed major reforms to revive growth.

Instead, the nationalist leader has focused on smaller initiatives including bank accounts for the poor. The “big-bang” reforms such as changes in goods and services taxes could prove unpopular and need state support to succeed.

Success for the BJP would also strengthen its power in the national upper house of Parliament, crucial for the passing of contentious laws. The BJP currently lacks a majority in that chamber whose composition is based on seats won in regional assemblies.

Modi, a fiery orator who dominated the national election, addressed 27 rallies during the campaign across Maharashtra, where the BJP lacks a regional party figurehead. He accused his opponents of “destroying” the state during their rule.

“He has to once again prove he is a vote-getter. There’s a lot at stake for him,” said Sudheendra Kulkarni, a political analyst at the Observer Research Foundation think-tank.

In Maharashtra, India’s second most populous state, Wednesday’s newspapers were covered in advertisements for the BJP with large pictures of Modi, calling on the electorate to choose “an honest and stable government.”

Despite the appeals, turnout in the first seven hours of voting was subdued in Maharashtra, at just over 30 percent of the electorate, while Haryana saw 50 percent.

Various Bollywood actors were seen heading to the ballot box in Mumbai such as Salman Khan and Shah Rukh Khan, along with cricket legend Sachin Tendulkar.

“All of us must exercise our right to vote. It’s really important for our nation.” Tendulkar told reporters.
