ISLAMABAD - The PPP-led government is delaying implementation of the Supreme Court verdict on Asghar Khan case for political advantage, sources said on Thursday.Political leaders and analysts suggest that the PPP, which has been wailing during the past few years that the apex court is not taking up the crucial Asghar Khan case, is appeared to be in compromising mode to implement the verdict."The ruling party seems to have compromised with the PML-N", renowned lawyer and Senior Vice President of Pakistan Tehreek-e-Insaf  Hamid Khan said while commenting on the statement of PPP minister Syed Khursheed Shah in which he said that Asghar Khan case has been buried.Shah told the media on Wednesday that the government did not want to implicate PML-N President Nawaz Sharif through FIA in Asghar Khan Case."Basically, both the parties were under tacit understating to protect each other to perpetuate their interest", Khan said while talking to TheNation.Sources told TheNation that PML-N and the PPP leadership have been protecting each other's interest but for the public consumption they pretend to be enemies."This kind of politics should come to end now, it is too much", said another lawyer, saying the Asghar Khan case has serious legal implications.On the other hand, the political observers believe that as the verdict has also restrained PPP co-Chairman President Asif Ali Zardari to use the Presidency for political activities, the PPP has adopted a new approach to promote the party interest.However, a senior PML-N leader rejected the impression that party's top notch had any tacit understanding with the ruling party. "Nawaz Sharif had himself welcomed the Supreme Court decision and offered to join the investigation process", the PML-N leader said, adding the party was still waiting for the government move to implement the landmark judgment.Another PML-N leader says that actually PPP was shying away from implantation the case because it knows that allegations against PML-N chief are baseless. "There are other people who have been charged by the Supreme Court in the case and why the government is reluctant to initiate probe", he said, adding that there was something fishy about the PPP strategy.
