岡田克也
After the crushing defeat of the DPJ in the 2005 snap election and the resignation of DPJ leader Katsuya Okada, the elected representatives of the party met to choose a new leader. The two candidates were Naoto Kan and Maehara. Maehara defeated the 58-year-old Kan by a razor-thin count of 96–94 in open balloting by party members from both Houses of the Diet, with two members abstaining and two others having cast invalid votes. Maehara was appointed DPJ president on 17 September 2005.
