"The entire Yadav family is involved in the Yadav Singh case... I will raise this issue forcefully in the next Lok Sabha session," Rajbhar said here.
On the clean chit to Mulayam given by Finance Minister Arun Jaitley, Rajbhar said Jaitley was not aware of the facts of the case and that he had issued the statement because of some misunderstanding.
He was referring to Jaitley' efforts to distance Mulayam from the Noida case during the last session of Parliament.
The MP upped the attack on the Uttar Pradesh government, calling it a failure on all fronts. "Instead of rule of law, criminals and corrupt are ruling the roost," he accused.
Meanwhile, when contacted, senior Samajwadi Party leader C P Rai said that Rajbhar was in the habit of making such unfounded statements and termed it an example of BJP's "alag chaal, charitra aur chehra". People were watching and evaluating such remarks, Rai said.
