The DPJ re-elected Ozawa as party leader for the third time on 21 September 2008. Ozawa stated on this occasion: "I will do my best, considering this is my last chance to put an end to the LDP-led government and bring about a government that puts a priority on people's lives." He was also announced by Secretary-General Yukio Hatoyama to have decided to switch from Iwate Constituency No. 4 to Tokyo Constituency No. 12 at the next House of Representatives election. On 24 September 2008, the House of Councillors, controlled by the DPJ, elected Ozawa as Prime Minister; however, the House of Representatives, controlled by the LDP, elected Taro Aso instead, overrode the upper house's decision.
