Former Defense Minister Takeshi Iwaya on Saturday denied receiving about ¥1 million ($9,250) in cash from a Chinese gambling operator involved in a suspected casino-bribery case.

Iwaya, a ruling Liberal Democratic Party member who has a seat in the Lower House, was one of five lawmakers questioned by Tokyo prosecutors on a voluntary basis for their alleged receipt of cash from the company, 500.com Ltd.

All five lawmakers have denied the allegations.
