Romania appoints Cimpeanu interim PM
The protesters have blamed widespread corruption for the deaths of 32 people in a nightclub fire and want widespread political reform.
President Iohannis has said he will hold further talks before making a final decision on a new prime minister.
He said he would consult civil society groups, as well as political leaders.
“I will, for Friday afternoon, call a group that represents both the civil society and what we call the street. It is important to me to know their views and options,” he announced.
Mr. Cimpeanu will take over the role of prime minister until a new leader is nominated and approved by parliament.
Without parliamentary approval, early elections will have to be called.
Mr Ponta, who is facing trial on corruption charges, had earlier gone on national TV to say he hoped his resignation would “satisfy the people who came out in the streets”.
