LAHORE - While paying rich tributes to PPP founder Z A Bhutto on the occasion of his 81st birth anniversary on Monday, party leaders demanded of the government to immediately start investigations into Benazir Bhutto's murder case without waiting for the UN probe. They were addressing different seminars organised in this connection here in the City. They renewed their pledge to complete the mission of Z A Bhutto and Mohtarma Benazir Bhutto Shaheed who struggled for the rights of down trodden people and sacrificed their lives for democracy. Three different functions had been organised in the City to mark the day; one at PPP's Faisal Town secretariat, another one at party's Baghbanpura office, while a third one was held under the aegis of Muslim-Christian Muslim Federation. Local party organisations also arranged similar functions in various Punjab districts. No cake-cutting ceremony was held this year due to Ashura-e-Moharram and in grief of Mohtarma Benazir Bhutto. The speakers in their speeches threw light on philosophy and political struggle of Z.A Bhutto with special emphasis on his services he rendered for the country in respect of making it a nuclear power and uniting Islamic countries on single platform. The PPP secretary general Jehangir Badr, Aitzaz Ahsan, Senator Dr. Safdar Abbasi, Naheed Khan, Rana Aftab, Altaf Qureshi, Dr Mehdi Hassan, Aslam Gurdaspuri, Raja Riaz, Samiulla Khan, Azma Bukhari, Munir Ahmad Khan, Azizur Rehman Chan, Abdul Qadeer Khamosh and Zekria Butt were the main speakers, who, in their speeches, remembered their leader as a great statesman, politician, orator and a firm believer in democracy and civil rights. Senior party leaders including Aitzaz Ahsan, Dr. Safdar Abbasi and Naheed Khan demanded of the government to start investigations into BB's murder case without any further delay to uncover the real culprits behind her assassination. Speaking on the occasion, Aitzaz Ahsan said that it was a matter of grave concern that despite lapse of one year, no headway had been made to uncover the murderers of Mohtarma Shaheed. He said it was not difficult to know as to who was responsible for removal of evidences from the crime scene at Liaqatbagh. Aitzaz said President Zardari was his leader and he may have differences with him on certain issues, but it was party's internal matter. He said he wanted to see PPP and Parliament stronger than before. "We will not do anything which destabilises the government, parliament and democracy", Aitzaz affirmed. Safdar Abbasi also called for initiation of inquiry into BB's murder case setting aside all expediencies and without caring for any body. He reiterated that leadership should bridge the gap between it and the party workers. Senator Abbasi vowed to work for the masses without caring for security following the footsteps of BB Shaheed. Naheed Khan, in her speech, said that issue of Justice Iftikhar Chaudhry's restoration should be brought to the parliament. "Justice Iftikhar is as loyal to the country as we are", she observed. Naheed was of the view that country's borders had become insecure and the situation in FATA was deteriorating day by day. She believed that solution to country's problems lay in complete implementation of Charter of Democracy, which was the brainchild of Shaheed Benazir Bhutto. She also demanded investigation into BB's murder case without waiting for UN probe, and added that nations who forget their leaders don't live longer. Jehangir Badr said democracy was the fruit of sacrifices rendered by Z.A Bhutto and Shaheed BB. He vowed to continue struggle for democracy till final triumph. Meanwhile, talking to media at party's Faisal Town secretariat, PPP's Punjab President, Rana Aftab said that ongoing energy crisis in the country was being politicised by certain political parties. To a question, he said that President Zardari was running party matters in accordance with BB's will. He belied the impression that gap between party workers and leadership was widening, saying that workers were supporting government policies. He said a meeting of Punjab PPP's general council has been convened on January 14 in Lahore to get feed back on party policies from party's office bearers. Replying to a question, he said that whosoever betrayed the party in the past, he was eliminated politically. He narrated names of former President Farooq Leghari, former Punjab Governor Mustafa Khar and Mustafa Jatoi in this regard to substantiate his point. Earlier, while addressing a seminar, PPP MPA, Azma Bukhari said that party leadership should take action against those party men who were issuing statements in violating of party policy.
