Egyptian Prime Minister Essam Sharaf has been taken to hospital after suffering a drop in blood circulation, state TV reported late Monday.
He is in stable condition, medical sources told the German Press Agency dpa.
This is the second time Sharaf has been taken to hospital since he was appointed in late March.
Sharaf has been in the process of reshuffling his cabinet for almost a week. He has been under pressure from Egyptian protesters to replace members of his government who served under ousted president Hosny Mubarak or had links with the formerly ruling National Democratic Party.
The reshuffled cabinet was scheduled to be sworn on Monday.
But the swearing-in ceremony had been delayed until Tuesday, official television reports said. It gave no explanation for the delay, which local media said was due to last-minute disagreement over candidates.
