NEW DELHI- Indian Prime Minister Narendra Modi suffered the first major setback as exit polls showed his party had been defeated in elections to Delhi's state assembly.

Five exit polls released indicated that the capital's former chief minister Arvind Kejriwal's Aam Aadmi Party had comfortably beaten Modi's Hindu nationalist Bharatiya Janata Party.

A steady stream of voters was seen outside polling booths throughout the day and the electoral commission put the provisional figure for final turnout at an impressive 67 percent.

"People want a corruption free Delhi and I'm hopeful they will vote accordingly,” Kejriwal told journalists.
