"The government I proposed is not perfect and was marred by some mistakes, so I changed it for the purpose of national unity," he said.
Independent lawmaker Nizar Kawan, who is aligned with the Muslim Brotherhood in Libya, said the Islamist group's party and a liberal coalition led by former rebel prime minister Mahmoud Jibril had been holding talks about replacing Abushagur with an independent figure who has no political background. The candidate would then be tasked with forming a government that is run by well-known professionals and is politically balanced and geographically representative.
Abushagur had taught engineering at the University of Alabama for about 17 years before leaving in 2002. He was active in the opposition abroad against Gadhafi prior to last year's uprising.
According to Libya's transition plan, after the formation of a government a new constitution is to be written and voted upon in a national referendum.
