The seven major political parties agreed Tuesday to convene a 13-day extraordinary Diet session from July 28, the parties’ Diet affairs chiefs said.

At the outset of the session, Prime Minister Yoshiro Mori will give his keynote address for the first time since his new Cabinet was launched earlier this month, they said.

During the session, Cabinet members are expected to give the Diet an account of the results of the Group of Eight summit to be held in Okinawa between July 21 and July 23.

The main issues to be taken up by the budget committees of both Diet chambers during the session include a controversial government plan to forgive debts held by ailing department store operator Sogo Co. and a recent bribery scandal involving Eiichi Nakao, a former construction minister and Liberal Democratic Party politician.

The opposition, which had insisted that the session be convened prior to the summit so that lawmakers can consider the government’s policy on the G8 summit, accepted the Diet schedule on the condition that the ruling camp arrange a meeting between the prime minister and opposition leaders to exchange opinions before the summit.
