BJP on Friday accused Arvind Kejriwal of forming a government in Delhi by "deceit" without a mandate of the poeple and resigning to cover up his failure to deliver on his commitments.
BJP also charged him with forming an "immoral" alliance and a government which showed "utter disrespect" to constitutional systems and institutions.
"This was one government which was not having a mandate.
It came by deceit. They formed an alliance which was immoral and full of internal contradictions.
"In their short regime, they displayed anarchy on several occasions and utter disrespect to Constitutional system and institutions," said BJP spokesperson Sudhanshu Trivedi.
He said finally when he realised that he was unable to fulfil his commitments made to people, he decided to resign to "cover up his failures".
Criticising him for recommending dissolution of the assembly while resigning, Trivedi said he did not enjoy the confidence of the House and thus he cannot recommend so.
"After his government virtually lost the vote of confidence, they recommended that the House be dissolved, which only that government can recommend which enjoys the confidence of the House," he said.
Kejriwal's Aam Aadmi Party emerged with a stunning debut by winning 28 of 70 assembly seats in Delhi and was given support by Congress to form a government.
He took over as Chief Minister on December 28 with outside support of eight Congress MLAs after the assembly polls in Delhi threw up a hung verdict with no party getting majority.
