Lucknow, Jan 22 (UNI) After a long suspense and even reports of breaking the deal, the pre-poll alliance between ruling Samajwadi Party and Congress has been finalised for Uttar Pradesh assembly elections. The deal was finally happened after a capping hectic negotiations that reportedly went on till about 4.30 am this morning in New Delhi. The sources said the Samajwadi Party has now agreed to allot 105 of UP's 403 seats for the Congress to contest as its junior partner, up from the 99 offered yesterday. UP Congress president Raj Babbar and his SP counterpart Naresh Uttam would hold a joint press conference at the SP office this evening at 1730 hrs to close the deal. However, the first information about deal the was disclosed by Congress leader Ahmed Patel through his tweeter post. "Wrong to suggest lightweights were dealing on behalf of Congress party. Discussion was at highest level- b/w CM (UP),GS I/C & Priyanka Gandhi," tweeted Patel this morning. Ms Vadra was closely involved, reportedly holding detailed discussions with both Akhilesh Yadav and his wife Dimple. But when talks broke down yesterday, with both sides refusing to yield any more ground, Sonia Gandhi had to reportedly step in to salvage the alliance. Mrs Gandhi's intervention is however stoutly being denied by Congress leaders so that Priyanka Gandhi's role is not undermined. Late last night Ahmed Patel, who is a close aide of the Congress chief and is said to have worked the phones on her behalf, tweeted that he had not called any Samajwadi Party leader. However, a Samajwadi Party leader who was part of the negotiations told NDTV that if the alliance has happened, it is because of Sonia Gandhi's intervention. The Congress has considerably scaled down its demand from the 138 seats that it had asked to contest as negotiations began. It was not known yet whether the Samajwadi Party has thrown in seats for the Congress in Raebareli and Amethi, the parliamentary constituencies of Sonia Gandhi and her son and deputy Rahul Gandhi, as part of the new deal, a major prestige point for the Congress. There are 10 assembly seats in Raebareli and Amethi, seven of which were won by the Samajwadi Party in the last assembly election and two by the Congress. Till yesterday, the Samajwadi Party was clear it would not allot the seats it had won to the Congress just because of the alliance. A formal announcement of the alliance was expected on Friday, but hours before that Akhilesh Yadav had announced candidates for 207 constituencies which will vote in the first two phases of the UP election, including in his list nine seats that were won by the Congress in the last assembly elections in 2012. The Congress had called that "unfortunate" as the proposed alliance appeared to come undone. UP will vote in seven phases from February 11 next month and results will be announced on March 11.
