Question hour in Lok Sabha was stalled for more than an hour as irate Samajwadi Party members clashed with the BSP after Mulayam Singh Yadav alleged that Uttar Pradesh CM Mayawati — facing allegations of corruption — was threatening to arrest him under POTA for raising his voice against her corrupt practices.SP members stormed the well followed by BSP members who trooped into the well in retaliation, shouting slogans against the SP. Speaker Manohar Joshi intervened after question hour and ruled that the notices of breach of privilege given by SP member Ramjilal Suman and RJD leader Raghuvansh Prasad Singh against Mayawati for her reported statement that MPs were earning commissions from their constituency development funds was ‘‘under my consideration’’. It would be taken up ‘‘in due course of time’’, he informed the LS.Mulayam levelled harassment charges against the UP CM claiming that his brother’s house in UP was raided by police. Joshi has called a meeting of leaders of various political parties to discuss the matter. Rejecting the SP’s notices of adjournment motion, he asked the MPs squatting in the well to return to their seats and raise the issue under different rules.
