Early results from Libya's first national elections in nearly five decades show moderate Mahmoud Jabril holding an impressive lead.

Jabril, who served as interim prime minister in Libya's National Transitional Council, may carry as much as 80 percent of the vote in Tripoli and 60 percent in Benghazi, plus strong leads in the south, Britain's The Guardian reported.

In stark contrast to governments elected in Tunisia (Salafist Reform Front) and Egypt (Muslim  Brotherhood's Freedom and Justice Party and the Salfist al-Nour Party), a win by Jibril would defy expectations by Islamist groups.

Though final results from Saturday's parliamentary election may be days away, Jibril extended a hand to other parties in Libya.

"We extend an invitation continued as before, to other political forces to come together in one coalition under one banner," Jabril said Sunday evening from his party headquarters in western Tripoli. "This is a sincere call for all political parties to come together. There are no extremists."

Many Libyan voters oppose the Muslim Brotherhood because it had cooperated with the nation's dictator, Moammar Gadhafi.
