Not that it really matters any more but can any official or PPP office-bearer clarify whether PM's trip to Garhi Khuda Baksh on December 25 to pay homage to late Benazir Bhutto was an official or a private one? If it was an official visit, why was the taxpayer's money utilized for a private purpose. If it was a private visit, did the PM travel on a commercial flight or paid for all expenses from his own pocket? -DR IRFAN ZAFAR, Islamabad, via e-mail, January 2.
