IT is quite strange that Punjab Governor Salman Taseer and PPP legislator Qasim Zia should be turning a deaf ear to the instructions from the Prime Minister and the President on maintaining party discipline. Both Mr Taseer and Mr Zia have adopted a hostile attitude towards the PML-N, issuing provocative statements. The President and the PM, according to TV channels urged Mr Taseer and Mr Qasim to exercise caution and restraint. However their denial that they had received any instructions of the sort is quite odd, which indicates that the party lacks discipline. While talking to this paper, Mr Taseer clarified that they had not received any instructions from above. What is more. Mr Zia was bold enough to remark that no one could stop him from expressing his thoughts. The PPP's top leadership should see to it that none of its members is allowed to sabotage the party's policy on vital issues. And it bears repeating that it is not for the first time that the Punjab Governor has engaged in sabre-rattling. Ever since his assumption of office, he had been making provocative statements, which proved quite significant in messing up the political landscape. The sad part is that all along no one from the party's top stepped forward to tell him to stop. Given the low point the bilateral relations have reached, extreme caution is needed. Mudslinging from either side would exact a heavy toll on the country's stability. The ray of hope, however, is Prime Minister Gilani, who assured Punjab Chief Minister Mian Shahbaz Sharif in Islamabad on Monday that the PPP government would not be a party to any undemocratic move that tended to destabilize the government in Punjab. The Prime Minister, who wanted to have a heart-to-heart with Mr Sharif, himself arranged the meeting that speak volumes about his desire to strengthen the relationship. Nonetheless, it is obvious that relations between the centre and Punjab hinge on several factors. Foremost among them are the restoration of deposed Chief Justice Iftikhar Chaudhry and his brother judges, and the outcome of the Sharif brothers' electoral eligibility case, being heard in the Supreme Court. For his part, Mian Nawaz Sharif also seemed to be upping the ante a bit when he said the other day that he would, if required, take a step further than sit-in to have the judges restored. It is extremely necessary that the PPP leadership solves the problem in accordance with its commitment. Leaving everything to chance would be unwise.
