India's triumphant right-wing opposition said Tuesday it was headed for a decisive majority in the world's biggest election after exit polls showed its hardline leader Narendra Modi closing in on victory.
Stock markets surged to record highs on hopes of a business-friendly government under Modi after a decade of rule by a left-leaning coalition, while US President Barack Obama said he looked forward to working with the new administration in New Delhi.
"Modi at Delhi Gate" said a headline in the Mail Today, while the Hindustan Times read simply "Exit Polls: Enter Modi" after a flurry of surveys released after voting ended Monday pointed to a big win.
All forecasts showed Modi's Bharatiya Janata Party (BJP) and its allies trouncing the Congress party which has been in power for a decade, and most indicated they would seal a narrow majority.
Results are due on Friday, with some still cautioning against over-confidence in a BJP victory given notorious forecasting errors at the last two general elections.
Modi was keeping a low profile, but senior BJP figures struck a bullish note by predicting the opposition would win more than 300 of the 543 seats in parliament although it was willing to work with additional partners.
"These elections have been fought on a hope that the country will get a good, stable government," V. K. Singh, a former army chief of staff who is now a senior BJP leader, told reporters at party headquarters.
"After May 16, we will be open to working with any, all entities that wish to work with us for the country's well being and development."
Asked about the exit polls predicting a majority for the BJP-led alliance, Singh replied: "We may perform even better than this."
Party spokesman Prakash Javadekar predicted that the BJP-led alliance would get more than 300, echoing Modi's chief lieutenant Amit Shah.
"My personal view is that we will get around 300 seats," Shah said.
"We will still be open to support and collaboration from any party that wants to work with a government that is committed to work for the nation," he told the Headlines Today network.
Reacting to the end of five weeks of voting that saw a record turnout of 551 million people, Obama said India had "set an example for the world".
"We look forward to the formation of a new government once election results are announced and to working closely with India's next administration to make the coming years equally transformative," he added.
Modi's election would present a headache for the US, which refused to deal with him for years in the aftermath of religious riots in the state of Gujarat in 2002 shortly after he became its chief minister.
More than 1,000 people, mostly Muslims, were killed in the violence, which critics say Modi did little to stop, even though a court-appointed investigation team cleared him of any wrongdoing.
Washington only ended its boycott of Modi in February when Nancy Powell, the outgoing US ambassador to India, met him for talks in Gujarat.
European countries also refused to deal with him for years in the wake of the 2002 riots, for which Modi has refused to apologise.
Stocks race higher
Foreign and domestic investors have few misgivings about his past, however, and appeared in no mood to heed the warnings about unreliable pollsters.
"The expectation is that (the BJP alliance) will get to form the government comfortably and even if they need more allies they will not present a stumbling block for reforms," Harendra Kumar, head of Mumbai-based brokerage Elara capital, told AFP.
The Bombay Stock Exchange index, also known as the Sensex, showed gains of nearly two percent at one stage, hitting a new record high before dipping slightly in early afternoon trade.
The Sensex has now gained around 22 percent since the BJP chose Modi as its prime ministerial candidate in September.
