TOKYO (AFP) - Japan’s election next month will be a messy battle, media said Saturday, with more than a dozen parties fielding candidates and some of them trying to forge a “third pole” between the two largest camps. Yoshihiko Noda, Japan’s sixth new prime minister in as many years, dissolved the lower house of parliament Friday in a political gamble widely expected to strip his centre-left party of power. Having had almost two-thirds of the 480 lower house seats when they came to power in 2009, Noda’s Democratic Party of Japan (DPJ) had lost its majority by Friday morning as a number of lawmakers jumped ship as the vote nears. Observers say no single party will have the numbers to govern alone after the election.
