Prosecutors on Friday demanded that former lawmaker Takanori Sakai of the Liberal Democratic Party -- accused of not reporting 168 million yen in political donations and defrauding the state of 24 million yen -- be sentenced to four years in prison.

During the hearing at the Tokyo District Court, the prosecutors also demanded that Sakai's former state-paid policy secretary, Aki Shionoya, 40, be sentenced to three years in prison.
