The AAP also said that it was the responsibility of the BJP, which is the single largest party, to form the government in Delhi.

After a meeting of top party leaders at party chief Arvind Kejriwal's residence, AAP leader Yogendra Yadav said, even if Lt Governor Najeeb Jung invites the party to form the government it will decline such an offer citing lack of majority.

"We are not going to form the government. We will sit in the opposition and play the role of a constructive opposition. As per the Constitution the largest party has to take the responsibility of forming government," Yadav said.

"We have not got majority so it is very surprising that the number one party (BJP) is not ready to form the government and telling us to do so," he said.

Yadav also strongly ruled out taking support of Congress to form government.

The BJP has also expressed its reluctance to stake claim, saying it did not have the numbers to provide a stable government.
