Rehabilitating disgraced Olympus Corp. should begin with the ouster of many of its current board members, former President Michael C. Woodford said Friday in Tokyo.

"These people cannot continue as directors" if the company is to properly account for its coverup of huge investment losses and manage to put the scandal behind it, Woodford told reporters at the Foreign Correspondents' Club of Japan.

Former Chairman Tsuyoshi Kikukawa and Executive Vice President Hisashi Mori resigned from the company's board Thursday, while auditor Hideo Yamada also stepped down the same day.
