Benazir Bhutto was so fearful for her life that she tried to hire British and American security experts to protect her, The Sunday Telegraph can reveal.
But the plans collapsed because President Pervez Musharraf refused to allow the foreign contractors to operate in Pakistan, according to senior aides.
"She asked to bring in trained security personnel from abroad," said Mark Siegel, her US representative. "In fact she and her husband repeatedly tried to get visas for such protection, but they were denied by the government of Pakistan."
Ms Bhutto's entourage discussed deals with the American Blackwater operation, this newspaper has learnt. Sources within the British private security industry said that she also had negotiations with the London-based firm Armor Group, which guards UK diplomats in the Middle East - last night the company said that it had no knowledge of any talks.
A Blackwater spokesman confirmed the negotiations. "We were approached to provide prime minister Bhutto's security, but an agreement was unfortunately never reached," she said. She declined to go into the precise details.
Ms Bhutto contacted officials, diplomats and friends in America, Europe and the Gulf to urge Gen Musharraf to improve her security following the suicide bomb attacks that killed more than 140 during her homecoming parade on Oct 19.
