TOKYO (Reuters) - Japanese Transport Minister Keiichi Ishii said on Friday he wanted Mitsubishi Motors Corp to respond "with integrity" after revelations that it cheated on test to measure fuel economy, including by possibly buying back the cars in question, Kyodo news reported.
Ishi also told a regular news conference the ministry will re-examine its methods for testing vehicles' fuel economy, according to Kyodo.
Mitsubishi Motors' shares plunged as much as 16 percent to a life-time low early in early trade. They were untraded all day on Thursday amid a glut of sell orders.
