Libya's election on Saturday could well bring Islamists to power, but liberals under the leadership of the architects of the revolt that ousted Moammar Gadhafi say they too are confident of a win.

Libya's outgoing National Transitional Council said on Thursday that Islamic law (sharia) should be the "main" source of legislation and that this should not be subject to a referendum.

Libyans vote on Saturday for a constituent assembly, the first body elected since the ouster of dictator Moammar Gadhafi, tasked with steering the country through its critical transition.

Moammar Gadhafi’s last premier, Baghdadi al-Mahmoudi, who was controversially extradited from Tunisia to Libya to face justice, said on Tuesday that he was innocent.
