AAP had launched a message campaign Tuesday evening to know if it should form a government after the Dec 4 elections resulted in a hung assembly.
The Bharatiya Janata Party (BJP), the single largest party with 31 seats in the 70-member house, had declined to form a government. The AAP netted 28 seats and was invited, but it sought time to reply.
The Congress party was routed in Delhi elections, winning only eight seats, and offered outside support to the AAP..
