Incumbent First Secretary François Hollande announced that he would not run again, opening the way for a three-way battle between 2007 presidential candidate, Ségolène Royal; Bertrand Delanoë, Mayor of Paris; and Martine Aubry, mayor of Lille.

Six motions were presented to be voted upon by members: 128,978 out of 233,000 eligible voters took part in the election by motion, which represents a turnout of 55.38% Bertrand Delanoë dropped out of the race for First Secretary during the Reims Congress and endorsed Martine Aubry the next day.

Ségolène Royal stayed in the race, as did Benoît Hamon (endorsed by Utopia).

According to official results, Aubry won by a tiny margin of 42 votes, although Royal did not concede and called for a third round to be held.
