It seems that former Sindh Home Minister will cause the MQM more grief. Its reaction to his presence in London, his impending address to the UKs House of Lords, and the presence of Sindh Information Minister Sharjeel Memon, has been to ask its senior ruling partner to explain. Dr Mirza has apparently created more waves after leaving the cabinet than within it, and his attacks on the MQM have created the impression that his address to the UKs Upper House will be directed against MQM chief Altaf Hussain, who has been there in exile since 1993. Mr Memons being with him lends credence to the belief that Dr Mirza is operating with the blessings of President Asif Zardari, and through the Sindh government. This has made Altaf Hussain call President Zardari by phone, and a ministerial MQM delegation met Prime Minister Yousuf Raza Gilani who assured them that an investigation into the matter would be held. Though the Gilani government would remain in office if the MQM was to leave, it would do so only because of the support of the PML-Q. The MQM has twice left the government before, and only PML-Q support prevented the collapse of the government. After the second return, which also included the resignation of Sindh Ministers and the Sindh Governor, it was generally thought the MQM would remain in the coalition until the time came for fresh elections, but the attacks on Altaf Hussains person had not been made, and the refusal of the PPP to take action against Dr Mirza had not raised suspicions within the MQM that he was acting within the blessings of a higher authority. The PPP must now count the cost of its clinging to both the MQM and Dr Mirza. It must not be forgotten that it was he who left the Sindh cabinet; he only had his portfolio changed. The MQM itself has been cautious in acting against Dr Mirza, who has accused it of involvement in the target killings which plagued its stronghold of Karachi, an accusation that cannot be dismissed because of the portfolio he held, but the PPP has found that the alliance also means that the commissionerate systems restoration was very much a bone of contention between the two allies. As a result, there were a number of flip-flops by the government over the issue, which added uncertainty to an already difficult situation. The PPP must adopt a clear policy, and if it indeed supports Dr Mirzas views, it should make this clear. The MQM should also make its own position clear, and it should take a decision whether or not it can continue in office. Whatever it decides, the government must respect it.
