ISLAMABAD - The Powerful Interior Minister Rehman Malik is presumably doing his last challenging task to restore peace in the restive Karachi city before he is relieved, sources said on Tuesday. Well-placed sources told TheNation that President Asif Ali Zardari has decided in principle to get rid of Rehman Malik as he has become a political baggage after serious allegations levelled against him by a senior party leader Dr Zulfikar Mirza. They were of the view that absence of Interior Minister in the crucial late night meeting chaired by President Zardari was clear indication that he would be relieved of his job after surmounting the challenging Karachi task. Sources said that President Zardari wanted to retain him in the government till conclusion of crucial Benazir Bhutto assassination case. But he had to change his mind following pleas from senior party colleagues especially from Sindh and above all his son Bilawal Bhutto Zardari. Sources said that the President was convinced that presence of Rehman Malik would be heaviest political baggage for the budding PPP new Chairperson Bilawal Bhutto Zardari slated to take reigns of the party next month. Sources were of the view Bilwal Bhutto Zardari who has been tipped to contest elections for Lyari seat in Karachi in future could win preferred election only when Rehman Malik had no role in the party decisions. Sources further said that fiascos created by Dr Zulfikar Mirza targeting Rehman Malik and MQM and their deep connections had left no moral ground for the party high command to retain him particularly when the party has to contest general elections with a new chairman in the near future. They were of the view that Dr Zulfikar Mirza had created diving lines within the part ranks and fold leaving the party leadership with no option but to get rid of Rehman Malik. Some sources believed that Dr Zulfikar Mirzas outburst against Rehman Malik might also delay President Zardaris plans to launch Bilawal Bhutto as fulltime party chief next month. This, they maintained could be because of preoccupation of Rehman Malik in Karachi operation and until and unless he successfully surmounts the given task he would not be relieved. As regards his future role, sources privy to these developments said that at the most he might be appointed as Pakistans ambassador to France or United Nations.
