Court issues arrest warrant for Pakistani PM nominee ISLAMABAD (Reuters) - A court has issued an arrest warrant for the ruling party veteran poised to replace Pakistan's ousted prime minister, local television stations reported on Thursday, deepening political uncertainty in the strategic U.S. ally. Pakistan's president had nominated Makhdoom Shahabuddin as the Pakistan People's Party (PPP) candidate in an apparent bid for continuity ahead of elections due early next year. Shahabuddin, the textiles minister, filed his nomination papers on Thursday. In an unexpected twist to Pakistan's latest political saga, an anti-narcotics court issued an arrest warrant for Shahabuddin in connection with a case of violated quota limits for the export of ephedrine while he was health minister. That case allegedly involved Gilani's son, Ali Musa Gilani, who is accused by anti-narcotics investigators of violating the quotas. Gilani and Shahabuddin have denied any wrongdoing. Shahabuddin's nomination papers were approved by parliamentary authorities, but his bid for premiership could be undermined by the court orders. He avoided questions from reporters about the court orders after filing his nomination papers, responding with only a line of poetry about adversity. The PPP nominated two other candidates, former information minister Qamar Zaman Kaira and former water and power minister Raja Pervez Ashraf, as candidates for prime minister as well. Leaders of the ruling coalition parties are meeting in Islamabad to further deliberate on their pick for prime minister after the warrant for Shahabuddin, adding to the drama in the build-up to Friday's vote in parliament. At the time, a senior aide to Gilani said only parliament could dismiss the prime minister, raising the possibility of a confrontation between the judiciary and government, but by nominating a new man the president has accepted the ruling and backed away from a fight. The new prime minister will face mounting public frustrations over a staggering range of problems, and a Supreme Court chief justice who prides himself on standing up to Pakistan's most powerful players. Gilani's removal is likely to further heat up the Pakistani political arena, where the civilian leadership, the powerful military and the Supreme Court square off against each other at the expense of a public longing for stability and a stronger economy. Shahabuddin's warrants were sought by Pakistan's Anti-Narcotics Force, a government body run by the military, and headed by a senior serving army officer. Analysts say the timing of the move is suspicious. To have so much movement so quickly on this case in one day is unusual. You don't usually see such efficiency in Pakistan, and the (Anti-Narcotics Force) is controlled by the army," said political analyst Hasan Askari Rizvi. It appears to a message that the army is also watching the process closely.
