A coalition headed by former rebel leader Mahmoud Jibril is leading the polls in Libya’s first post-Gaddafi elections, according to preliminary polling results from the key constituencies of Tripoli and Benghazi.

Jibril, the former executive bureau chief of the ruling National Transitional Council (NTC), leads the National Forces Aliiance (NFA) bloc.

The preliminary results has the NFA leading in a number of constituencies, while the Islamist Union for Homeland bloc leads in the western city of Misrata, according to the Higher National Electoral Council (HNEC).

The HNEC is expected to release the final results on 11 July.

US-educated Jibril worked as an economic adviser to Saif al-Gaddafi, but resigned following the outbreak of fighting in February 2011, then led the NTC during the Libyan civil war from March to October 2011. He resigned from the NTC just three days after it declared victory.

The NFA is the second-largest bloc in the elections after the Justice & Construction Party, fielding 70 candidates across Libya. According to the Libya Herald, the NFA is widely considered liberal, but does not describe itself as secularist. Jibril himself has described the bloc as a moderate Islamic movement, favouring Sharia as the basis of law.
