ISLAMABAD - After the failure of London round of talks between Pakistan People's Party and Pakistan Muslim League (Nawaz) and 'technical' lapse of the second deadline for the restoration of judges, the leadership of PPP back home is engaged in hectic backdoor contacts with the N-League to keep it on board in the coalition government. Sources in the PPP disclosed to TheNation that the leadership of the party was quite perturbed over the news of talks' failure pouring in from London and was engaged with the PML-N colleagues in the federal cabinet and in the Parliament to play their role in keeping the coalition boat afloat. PML-N Central Working Committee and Parliamentary Party joint meeting is called here on Monday (today), the D-day of second deadline given by Mian Nawaz Sharif for restoration of the judges after the Dubai parleys with PPP Co-Chairman Asif Ali Zardari. The PML-N leadership back home including Senior Federal Minister for Communications Ch Nisar Ali Khan, Makhdoom Javed Hashmi and others have made it loud and clear many a times if the judges are not restored by May 12, they would quit the federal cabinet. But at the same time, they said that they would not withdraw support to the coalition government. The PPP leadership is of the view that N-League should stay with them in government, as PPP was committed to restore the deposed judges in the light of Bhurban Summit Declaration signed in March this year. The point of difference was just on the modus operandi and it would be resolved in due course of time. Mian Nawaz Sharif, though committed to the judges' restoration without any pre-conditions and its linkage to constitutional package, had shown some flexibility by saying that they would not opt for the 80s and 90s style of politics of revenge and agitation. He candidly said that the PML-N went extra-mile to get the issue resolved but could not make it and now would decide about the future course in the CWC meeting scheduled to be held today. The sources in the PML-N informed that the PML-N was left with no option but to quit at least the federal cabinet and let the PPP go about the restoration of judges in its own way. However, some key persons in both PPP and PML-N are still optimistic about the future and fate of the coalition. They said that on Monday PML-N wouldn't announce resignation from the federal cabinet and at first stage its federal ministers would stop attending their offices to pressurise PPP on the issue. The PML-N could quit the federal cabinet at some later stage if the issue of judges would not be resolved by the PPP, they added. Political observers are of the view that though PML-N leadership is saying that they will quit the federal cabinet and continue extending support to the coalition government, but practically it would not be possible for them to stretch it for longer period, as in case of lingering of the judges' issues the lawyers and APDM component parties would come on streets and it would become almost impossible for PML-N to stay aloof from these developments. The political analysts see the prevailing political situation in the country fluid in which anything could happen and the smaller parties in the Parliament and independents could reap the benefits of this uncertainty. These analysts said that in case PML-N parted ways with the ruling alliance the non-entities in the Parliament would become active and once again the political dispensation would come under the thumb of the 'establishment'. In another major development, the US Assistant Secretary of State Richard Boucher separately met Mian Nawaz Sharif and Asif Ali Zardari in London on Sunday and ostensibly discussed regional issues with both these leaders. But political analysts term it a very significant development as United States did not want to see instability in Pakistan, as it would affect the ongoing international war on terror going on in Afghanistan and adjacent tribal areas of Pakistan.
