Patna, May 21 (IANS) Attacking Bihar Chief Minister Nitish Kumar over rising crime in the state, RJD member of parliament Mohammad Taslimuddin on Saturday said his party should walk out of the ruling 'grand alliance' with the JD-U and the Congress.

"There is no justification for this grand alliance. The RJD should break it. I personally want it to be broken but the final decision has to be taken by RJD chief Lalu Prasad," Taslimuddin, a controversial former union minister, told reporters here.

Taslimuddin, who represents Bihar's Araria constituency in the Lok Sabha, said there was indeed "jungle raj" in the state and crime is increasing like never before.

"It is the duty of Nitish Kumar to maintain law and order. I will launch an agitation if law and order is not improved."

He said Nitish Kumar looked as if he was not fit to be a village head, let alone a chief minister.

"He is not fit for the post of mukhiya (village body head). He has been looting Bihar in the name of development," Taslimuddin said.

On Friday, Taslimuddin had demanded the resignation of Nitish Kumar for his failure to maintain law and order in the state.

Earlier, Rashtriya Janata Dal (RJD) Vice President Raghuvansh Prasad Singh and senior leader of the party Prabhunath Singh had trained their guns on Nitish Kumar.

Prabhunath Singh said: "If Shahabuddin (jailed criminal-politician of RJD) was holding Janata Darbars in jail, it only shows the administrative weakness of the government. If Darbars were being held regularly what were the officials doing."

Janata Dal-United (JD-U) leaders have been hitting back at RJD politicians, demanding that Lalu Prasad must rein in Taslimuddin, Prabhunath Singh and Raghuvansh Prasad Singh.
