Age: 60
Occupation: Chairman, National Transitional Council of Libya
Having found himself propelled into the leadership of Libya's rebellion against his old boss Muammar Gaddafi, former Justice Minister Abdel-Jalil is now serving as the acting President of a country in transition — and in danger of collapse. With limited leverage of his own, Abdel-Jalil's prospects of success — and Libya's for avoiding a descent into chaos — depend entirely on his ability to forge a consensus among the country's fractious militias.
