Leftist politician Godah Abdel Khalek, meanwhile, declined an offer to return to the post of minister of supply in Egypt ' s interim government, citing personal reasons.
Two sources in Egypt ' s transitional administration had earlier said Interim Prime Minister Hazem El - Beblawi would ask Abdel Khalek to serve in the post.
" I was offered the post by Biblawi, but I declined for personal reasons, " he told Reuters over the phone.
Abdel Khalek had held the post before for a few months in 2011.
Biblawi, an economist and former finance minister, was named interim prime minister last Tuesday and Mohamed ElBaradei, a former UN diplomat, was named vice president for foreign affairs.
Biblawi is now assembling a government to lead Egypt under an army - backed " road map " to restore full civilian rule.
Biblawi began the task last Wednesday meeting ElBaradei and liberal politician Ziad Bahaa - Eldin.
Biblawi told Reuters last week he accepted that it would be difficult to win the unanimous support of Egyptians for his new government.
" Of course we respect the public opinion and we try to comply with the expectation of the people, but there is always a time of choice, there is more than one alternative, you cannot satisfy all of the people, " he said.
