The three-member panel, led by Chile's UN Ambassador Heraldo Munoz, has ruled out making any changes in the report, which was scheduled to be released on Mar 30 but was delayed following Pakistan President and Bhutto's husband, Asif Ali Zardari's request.
"The Commission of Inquiry that was formed to determine the facts in the 2007 assassination of former Pakistani Prime Minister Benazir Bhutto will formally present the report on its work to the Secretary-General (Ban Ki-moon) on Thursday afternoon," UN spokesperson Martin Nesirky told reporters.
"The Secretary-General then intends to transmit it to the Government of Pakistan, and he will also share it, for information purposes, with the members of the Security Council," he added.
Dissatisfied with the investigation carried out by then president Pervez Musharraf's government, Zardari asked for UN probe into the killing of his wife.
Bhutto was killed on Dec 27, 2007, in a gun and suicide attack after addressing an election rally in Rawalpindi.
Musharraf government had blamed Pakistani Taliban commander Baitullah Mehsud for the assassination.
The contents of the report will be revealed to the reporters at the UN headquarters after it is submitted to Secretary-General, Ban Ki-moon.
