Railway Minister Lalu Prasad Yadav on Tuesday maintained that Sangh Parivar activists were involved in the attack on him in Gujarat and reiterated his demanded for the dismissal of the Gujarat government.

"The Rashtriya Swayamsevak Sangh, Bajrang Dal and the Vishwa Hindu Parishad were behind the murderous attack on me," Lalu told Rajya Sabha after opposition National Democratic Alliance staged a walkout protesting the government's attitude towards it.

"Bajrang Dal and VHP activists attacked me from all sides. Ice bags were hurled on me from the hospital building. One of them [bags] scraped past me. The rear window of my car was damaged," he said.

Rejecting the demand for his resignation in the wake of the Sabarmati Express mishap, Lalu gave statistics of rail accidents during the previous NDA regime and asked why the then railway minister had not resigned.

"Thousands of people were killed in riots (in Gujarat). Why did (Atal Bihari) Vajpayee not remove Modi or seek his resignation? They are now teaching me lessons in morality," he said.

• Rajya Sabha adjourned over Lalu

On the opposition's demand for his resignation following the framing of charges against him in the fodder scam, Lalu quoted Vajpayee's statement of December 7, 1999 when the former prime minister had defended the continuation of Lal Kishenchand Advani, Murli Manohar Joshi and Uma Bharti as ministers after charge-sheets were filed against them in the Babri Masjid demolition case. Vajpayee had then said that filing of charge-sheets was not enough ground for removing them, Lalu said.

The railway minister alleged that the state government had failed to provide security to him during his Vadodara visit.

An affidavit by a senior police official on the role of Modi during the riots had exposed the state government, Lalu said. "Gujarat is a fit case for the imposition of President's rule," he added.
