New Delhi, Feb 15 (IANS): AAP leader and senior Supreme Court lawyer Prashant Bhushan said Saturday the party had no option but to quit after the Jan Lokpal bill was rejected in the Delhi assembly.

Bhushan said the bill was the first promise made to the public of Delhi.

"Our biggest responsibility was to form a corruption-free government and run it, but if the BJP and the Congress are not letting us pass the bill, then what is the point of us staying in power," he said.

He said that as the Bharatiya Janata Party (BJP) and the Congress were unlikely to form a coalition, Lt. Governor Najeeb Jung has no option but to dissolve the assembly.

On Kiran Bedi's statement that AAP was trying to hype the Jan Lokpal bill to ensure good results in Lok Sabha election, Bhushan said Bedi had become a mouthpiece of the BJP.

Arvind Kejriwal resigned as Delhi chief minister Friday after the Congress and the BJP combined did not allow the bill to introduced in the assembly.
