Patna, Nov 28 (IANS): A day after RJD leader Tejashwi Yadav took a dig at Nitish Kumar and provoked him enough to angrily hit back, Tejashwi's mother Rabri Devi on Saturday dubbed the Bihar Chief Minister as a "warrior of sophistry".

"He is a 'kutark ke yoddha' (warrior of sophistry). He claims that he made Tejashwi the Deputy CM of Bihar. It is absolute rubbish. He doesn't have any shame left. In the 2015 Assembly elections, we won 80 seats and the Janata Dal-United got only 69 seats. Tejashwi was the leader of 80 MLAs and Nitish did not oblige him by offering the post of Deputy CM. You (Nitish) have to thank Lalu Prasad ji for extending a political lifeline to you in 2015," Rabri told the media at her residence here.

"When a person becomes weak, he generally becomes angry and blows his fuse. Nitish Kumar is losing his cool these days and using unparliamentary language against the Leader of Opposition (Tejashwi). The CM is using highly objectionable words for him," said Rabri Devi, a former Chief Minister of Bihar.

Nitish Kumar on Friday lost his cool after a personal attack by Tejashwi, who said in the Assembly that Nitish Kumar did not become father to a second child as he was probably scared of girl child.

Tejashwi also alleged that Nitish Kumar was facing actions in a murder case of 1991 and that the case was closed recently.

An angry Nitish Kumar in his speech later in the Bihar Assembly accused Tejashwi of lying and indulging in idle chatter.

He also clarified that he had made the remarks about 8-9 children of people just to inject some humour during an election rally.

Meanwhile, Hindustani Awam Morcha (Secular) President Jitan Ram Manjhi said: "Tejashwi crossed the limit in the Assembly and used unparliamentary language to personally attack the Chief Minister. He should apologise. Nitish Kumar had made the remark at a political rally and not in the Assembly."
