Egyptian Prime Minister Essam Sharaf appointed economist Hazem Beblawi as the new minister of finance on Sunday, dpa reported.
Beblawi, a former undersecretary of the United Nations's Economic and Social Commission for Western Asia, was also appointed as deputy prime minister for economic affairs.
His appointment came shortly after Samir Radwan resigned from the post.
Radwan was first appointed by former president Hosny Mubarak in early February in a cabinet reshuffle that aimed at calming nationwide demonstrations.
After Mubarak was forced to step down on February 11, few of those he appointed remained in the new cabinet.
Sharaf has been under pressure from thousands of protesters to remove ministers who served under Mubarak or had links with the formerly ruling National Democratic Party or because have not been quick enough with reforms in their departments.
Radwan was a member of the Mubarak's party's political committee.
Both Trade and Industry Minister Samir al-Sayyad and Foreign Minister Mohamed al-Orabi resigned ahead of an imminent cabinet reshuffle, expected to be announced Sunday or Monday.
