Mitsubishi Motors Corp. President Katsuhiko Kawasoe plans to resign in connection with the firm's concealment of customer complaints and recalls, company sources said Monday.

Kawasoe is expected to quit after the Transport Ministry takes disciplinary steps against the automaker, the sources said.

The latest move came after police on Sunday raided MMC's head office and other facilities over alleged violations of the Road Trucking Vehicle Law. The automaker is under investigation for concealing customer complaints from government inspectors for several decades.
