A government advisory panel is to call for the conditional dismantling of the current holding company structure of Nippon Telegraph and Telephone Corp., according to a final report the panel is scheduled to release on Dec. 21.

In the report, a copy of which has been obtained by Kyodo News, the Telecommunications Council recommends that NTT submits a business plan that spurs competition. It says the holding company should be scrapped if the plan is not drawn up or its contents are unsatisfactory.

The report by the council, which advises the posts and telecommunications minister, also urges the government to show strong commitment to deregulating the telecom market by setting a deadline of "roughly two years" to check whether sufficiently competitive market conditions have been created.
