Libyans went to the polls Saturday in the country's first free national election since the toppling of longtime dictator Moammar Gadhafi last year. Voters are electing a 200-member assembly whose first task will be naming a new government. Here are some details about the key parties vying for seats:

THE JUSTICE AND CONSTRUCTION PARTY (ISLAMIST):

This is the main political arm of Libya's Muslim Brotherhood, though party leaders have tried to distance themselves from the Brotherhood name by saying the party is only co-founded by some of the group's Islamists. High-level members of the party include non-Brotherhood people.

The party is led by Mohammed Sawan, who spent eight years in prison under Gadhafi because of his affiliation with the Brotherhood. He is also a former member of the Brotherhood's top decision-making council in Libya.

The party's leaders have also said that it is independent from other Brotherhood groups in the region, including in Egypt, where a Brotherhood candidate was recently sworn in as president.
