TOKYO (Reuters) - Japanese Transport Minister Keiichi Ishii said on Friday he wanted Mitsubishi Motors Corp <7211.T> 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.
