A Liberal Democratic Party committee working on drafting a new Constitution decided Monday to have 10 subcommittees headed by former prime ministers and other key members draft reports by March on a new supreme law for the country.

Of the 10 subcommittees launched to handle the 10 principal chapters of the postwar Constitution, former Prime Minister Yasuhiro Nakasone heads one on the preamble, while former Prime Ministers Kiichi Miyazawa and Ryutaro Hashimoto will serve as head and deputy head of another on the emperor, former Prime Minister Yoshiro Mori told reporters.

Mori is heading the committee.
