Indian Prime Minister Modi and his allies are on course to a win a majority in parliament after a general election, according to exit polls.

The election was billed as a referendum on Modi’s government according to Indian media reports.

Indian Prime Minister Narendra Modi’s National Democratic Alliance (NDA) is likely to win at least 287 seats in the 545-member lower house of parliament, followed by 128 for the Congress party-led opposition alliance, exit polls showed on Sunday.

India’s Times Now television claimed that Modi’s alliance is likely to get 306 seats, a clear majority in parliament. One poll by Neta Newsx, however, forecast the NDA falling 30 seats short of a majority.

A total of 272 seats in parliament are required for a party to form a government.

Exit polls, though, are not completely accurate and have a mixed record in a country with an electorate of 900 million people. Official results are expected on Thursday.
