In a major setback to Samajwadi Party ahead of the voting for 10 Rajya Sabha seats in Uttar Pradesh, its chief whip in the Assembly resigned this morning. The resignation of Manoj Kumar Pandey, MLA from Unchahar, came hours after as many as 8 MLAs skipped a dinner hosted by party chief Akhilesh Yadav - a cause for worry amid the cross-voting buzz in the election to the Upper House. Besides hitting the SP's prospects in this key election, cross-voting will compound the party's worries months ahead of the general election. The SP will be contesting 63 Lok Sabha seats in Uttar Pradesh as part of the INDIA alliance and a mutiny months before the polls will be a massive blow.
