Early trends show Delhi's governing Aam Aadmi Party (AAP) heading for a big win in the Indian capital.
The party is leading in more than two-thirds of the state's 70 seats.
Delhi voted on 8 February after an aggressive campaign that saw BJP heavyweights such as Home Minister Amit Shah take to the streets to woo voters.
But exit polls predicted a big win for AAP, led by charismatic politician Arvind Kejriwal, who has campaigned on education and healthcare.
The two-term chief minister has been credited with turning around Delhi's government-run schools, establishing affordable neighbourhood clinics, and providing cheap water and electricity.
