The German Press Agency (DPA) reported that Hamburg's First Mayor Olaf Scholz, who will probably become Germany's finance minister in the upcoming new government, will provisionally take over the position of SPD leader until the April election.
Several state associations had formally objected to the immediate takeover of the top office by Nahles.
The change is a hope by the party's leadership committee to contain the bitter infighting which has continued despite Schulz's resignation from the role as SPD leader, as well as his more recent surrender of the prospective post as foreign minister in a new "grand coalition", referring the coalition between SPD and German Chancellor Angela Merkel's Conservatives Union.
Schulz's announcement came after a turbulent week for him. Last Wednesday, the SPD reached an agreement with Merkel's Union in formal government coalition negotiations, a move likely to end the longest ever new government vacuum after the September 24 federal elections.
