It also said Egyptian authorities had asked Al-Mahdi, who resides in Egypt, not to attend the conference. Egypt airport officials said in a statement Sunday that processing procedures had simply taken a long time and that Al-Mahdi later headed to London. They spoke on condition of anonymity because they were not authorized to brief the media. Egypt"s Foreign Ministry couldn"t be immediately reached for comment. Al-Mahdi, 82, was Sudan"s last democratically elected prime minister and was overthrown in a 1989 Islamist-backed coup.
