Opposition parties said Sunday they will demand former Chief Cabinet Secretary Hidenao Nakagawa be summoned to the Diet to respond to allegations that he leaked police information to his former mistress and is closely tied with a rightwing extremist.
Speaking on an NHK television program, Naoto Kan, secretary general of the Democratic Party of Japan, suggested Nakagawa be summoned to the Diet to make clear "whether Mr. Nakagawa can still deny what he has denied so far."
Other opposition leaders on the program, including Kazuo Shii, chief of the Japanese Communist Party Secretariat, voiced similar views.
