ISLAMABAD - Intense talks between the ruling PPP and the opposition parties on Monday to evolve consensus over ratification of the 20th Constitutional (Amendment) Bill-2012 from the National Assembly remained inconclusive because the stakeholders kept sticking to their positions on the issue of future caretaker setup.The four-hour-long negotiations were held at the Chamber of Leader of Opposition in the National Assembly Ch Nisar Ali Khan and would continue today (Tuesday) in a bid to break the impasse.The PPP team included federal ministers Syed Khurshid Shah and Syed Naveed Qamar and Senator Raza Rabbani, while opposition parties including PML-N, JUI-F and PPP-(Sherpao) were represented by Ch Nisar Ali Khan, Khawaja Muhammad Asif, Senator Ishaq Dar, Aftab Ahmed Khan Sherpao, Maulana Fazlur Rehman and Maulana Ghafoor Haideri.Later in their separate interaction with the reporters, Syed Khurshid Shah and Ch Nisar Ali Khan conceded that deadlock persists over the issue of future caretaker setup.Syed Khurshid Shah was hopeful that both sides would evolve consensus when they resume talks here today. However, Ch. Nisar Ali Khan said it would be very difficult for the opposition parties to compromise on the crucial issue, adding it has become very difficult for the PPP-led ruling alliance to get the bill through without the support of the PML-N.“Now after suspension of membership of nine MNAs by the Supreme Court, it has become very difficult for the ruling alliance to get the draft bill passed from the national assembly without the support of the PML-N.Nisar went on that PML-N, JUI-F and PPP-S were united to drive maximum leverage from the ruling alliance if it wanted to get the draft bill ratified with the consensus of the house.Syed Khurshid Shah said that the government has accepted three demands of the opposition parities relating to appointment of Chief Election Commissioner (CEC) and service tenure of members of the Election Commission of Pakistan and implementation of 18th constitutional amendment.In a related development, parliamentary sources said that the ruling alliance would present the bill before the house on Wednesday but this will be subject to achievement of consensus by the government and opposition.Earlier, while talking to reporters, Khurshid Shah said that the 20th amendment would be unanimously passed from the parliament, claiming that they had won over the support of Pakistan Muslim League-Nawaz (PML-N) on it.Shah said that under the agreement the tenure of provincial members of the election commission was enhanced from two to five years and they would take oath of their offices.The sources aware of the negotiations said that it was also agreed that the incumbent Election Commissioner would not be given extension after the expiry of his term in coming March while the new head of the election commission would be made strictly in the line with the procedure laid down in the 18th amendment.Meanwhile, the 20th amendment bill was deferred for the fourth consecutive time in the national assembly and the treasury members requested the chair to defer the matter as they were trying to evolve consensus on it.
