The Tokyo Stock Exchange said Monday it will delist scandal-tainted Livedoor Co. and subsidiary Livedoor Marketing Co. from its Mothers market for emerging firms on April 14 due to alleged accounting fraud.

The long-expected decision by the nation's main stock exchange came after the Securities and Exchange Surveillance Commission filed a fresh criminal complaint against Livedoor and its former executives on similar charges earlier in the day.

The TSE will transfer Livedoor and Livedoor Marketing to its delisting post, where it will stay until April 13 to give shareholders time to sell holdings. The two firms will officially be delisted April 14.
