ISLAMABAD: January 4, 2008. (AFP) - A Scotland Yard team that arrived in Pakistan on Friday to help investigate the assassination of opposition leader Benazir Bhutto will fail to shed any light on the murder, her party said. "This Scotland Yard team... what will it do here? It will work under the patronage of the government. It is going to be a meaningless exercise," said Farooq Naik He said the Pakistan People Party would not cooperate with any investigation other than one held under the auspices of the United Nations, such as the UN-led probe into the assassination of Lebanese Prime Minister Rafiq Hariri in 2005. "We reject it, we will not join it," Naik said. "An international investigation commission should be set up, appointed by the UN and answerable to the UN and nobody else." The government has already ruled out any UN-led inquiry into the assassination of Bhutto at an election campaign rally in Rawalpindi on December 27. Bhutto supporters have blamed President Pervez Musharraf for failing to provide adequate security for the two-time former prime minister, who had survived an earlier suicide bombing in October which left scores dead. It has also described the official version of her death -- from head wounds resulting from banging her head against her car as she tried to duck for safety -- as a farcical attempt to cover up the truth of what happened. Before her death, Bhutto had publicly accused senior government and intelligence officials of plotting to kill her after her return from self-imposed exile in October. Musharraf has angrily denied any government involvement in the murder. But he conceded to reporters Thursday that he was unhappy with the domestic investigation, amid questions over why the crime scene was washed clean immediately after the attack. Bhutto aides who were at the scene insist she died of gunshot wounds to the head, but the family refused to allow an official autopsy before her burial. Her assassination plunged Pakistan into political turmoil and forced the postponement of January 8 general elections until February 18.
