New Delhi, May 11 (IANS) Expelled Rashtriya Janata Dal (RJD) member Rajesh Ranjan alias Pappu Yadav on Wednesday blasted Delhi Chief Minister Arvind Kejriwal for his alleged attempts to lower the prestige of the office of prime minister and "hurting the sentiments of 125 crore people" of India.

He also took a critical stand against the Aam Aadmi Party leadership for its comments on Congress president Sonia Gandhi.

"Kabhi Sonia Gandhi ko jail bhejo, Kabhi pradhan mantri ko jhuta kahata hae (Sometimes he says, Sonia Gandhi should be sent to jail. Sometimes he says prime minister is a liar)," the MP from Madhepura said in Lok Sabha during zero hour.

Without taking any name, he said the same person and the party themselves do not show decency to decorum and established norms.

"They have passed as many as 16 such bills which do not come under their domain," he said alluding to Delhi chief minister and the assembly.

He wanted to know whether such leaders should not be asked to tender apology to the nation. Should there be a CBI probe or not on how by "uttering all falsehood" they (AAP) have created an atmosphere of "satta-ka-mahol (power game)" for themselves.

Yadav, who was expelled from Lalu Prasad-led RJD on the eve of Bihar assembly elections last year, had also floated Jan Adhikar party.

He said such utterances and allegations like questioning the educational qualifications of the prime minister is irrelevant to Indian politics.

"....but all these only show the country in poor light as if India's prime minister is so weak that people are questioning his educational credentials," Yadav said.

At one point, Speaker Sumitra Mahajan asked the member not to take any names.

Kejriwal's AAP has four members in the Lok Sabha but none were present when the issue was raised.

On April 26 also, Pappu Yadav had flayed the Kejriwal regime in Delhi over the odd-even traffic scheme stating that the measure has only added to people's problems.
