Yukio Hatoyama, leader of the Democratic Party of Japan, was elected party president for a second term at a party convention Saturday in Tokyo, pledging to establish a new DPJ-led government after the Upper House elections next summer.

Hatoyama's uncontested campaign for the presidency was approved at the convention, held at a Tokyo hotel, granting him another two-year term as head of the largest opposition party.

"This time, I am setting out amid a violent storm," Hatoyama, 53, said after confirming his re-election, referring to recent allegations of fraud involving former DPJ lawmaker Joji Yamamoto.
