BJP said that Kejriwal has no moral right to speak on government formation in Delhi as he has lost his credibility after quitting from power in 49 days and leaving the government in the lurch.
"The Lt Governor's a constitutional post and to cast aspersions on it is very unfortunate and irresponsible," said BJP secretary Shrikant Sharma.
"Kejriwal has lost out after his drubbing in the last Lok Sabha polls and is now fighting for his survival," he added.
Delhi Lt Governor Najeeb Jung has come under fire from AAP over the issue of government formation with the party having accused him of "promoting horse-trading".
Meanwhile, regarding the party's own stand on government formation, BJP said it would decide on the matter only after the Lt Governor invites them to take a shot at the same.
