LAHORE-The PML (N) has opened up back-door channels with PML (Q) to explore the possibility of fielding a consensus candidate against PPP Co-Chairman Asif Ali Zardari in the Presidential elections. Sources privy to the latest developments in the political arena, revealed that the PML leader Chaudhry Nisar Ali Khan met PML (Q) Secretary General Mushahid Hussain Syed in Islamabad on Monday night to discuss the prospects of cooperation in the Presidential elections. The sources disclosed that cooperation on this count could lead to wider cooperation between the two parties and even alliance in days to come.  The meeting took place hours after the PML (N) top leader announced his separation from the ruling alliance and decision to sit in the Opposition. According to the insiders, a former adviser to ex-CM Chaudhry Pervaiz Elahi from Lahore played an important role in melting the ice and arranged the meeting of Mushahid Hussain Syed and Chaudhry Nisar Ali at the Federal Lodges Islamabad. Both the leaders met after getting the nod from their top leadership Mian Muhammad Nawaz Sharif and Chaudhry Shujaat Hussain respectively. 'There was one-point agenda of the meeting- to field a joint and non-controversial personality as the Presidential candidate', sources said. Nisar tried to convince Mushahid to join hands with PML (N) in supporting its Presidential candidate, Justice (Reted) Saeed-uz-Zaman Siddiqui. The sources disclosed that PML (Q) General Secretary asked PML (N) leader that cooperation between the two parties was possible if the latter was ready to accept Chaudhry Pervaiz Elahi as Opposition leader in the National Assembly. According to the PML (Q) sources, both parties would be required to take important decisions including the decision to cooperate in future with each other in the next 24 hours. The sources said that the PML (Q) leader also told PML (N) leader that their side had announced the name of Justice (reted) Saeed-uz-Zaman Siddiqui as PML (N) candidate for Presidential slot in hurry. Both the leaders also agreed to remain in contact in future to evolve a joint strategy on national issues including restoration of judges and war against terrorism. Meanwhile, the sources further said that though Mushahid Hussain Syed has been nominated as PML (Q) candidate for Presidential race but his name would be withdrawn from the election if the dialogue with PML (N) is successful. Mushahid has been nominated for the Presidential race only to press PML (N) to sit on the dialogue table with the PML (Q). S.M. Zafar also attended this meeting, the sources added.
