The Japanese government and the ruling coalition led by the Liberal Democratic Party are discussing a plan to set the date for convening an extraordinary session of the Diet, or parliament, on Nov. 28, informed sources said Thursday.

The session will be convened to discuss a fiscal 2024 supplementary budget that will finance a planned economic package and proposed revisions to the political funds control law in the wake of the LDP's slush funds scandal.

There is also a proposal to set the date for convening the extraordinary session on Nov. 29 in consideration of Prime Minister Shigeru Ishiba's overseas visit schedule.

Diet affairs chiefs of nine ruling and opposition parties and one parliamentary group held a meeting in the Diet on Thursday. The opposition side reiterated their call for the early convening of the session. Also, they sought the immediate start of discussions on the criteria for disclosure of the use of research, public relations and accommodation allowances that the government pays lawmakers. The ruling side did not respond to the requests immediately.

Hirofumi Ryu, Diet affairs chief of the main opposition Constitutional Democratic Party of Japan, told reporters after the meeting, "With the opposition camp having a majority (in the House of Representatives), we will deliberate exhaustively before reaching conclusions."

Ryu also said, "The ruling and opposition parties must work together to show (the public) what the new Diet should be like."

As the preceding special Diet session was convened only for a four-day run through Thursday, the extraordinary session will be the first occasion of full-scale deliberation for the prime minister since the Oct. 27 general election for the Lower House.

As the parties have differing positions on the proposed abolition of what are known as policy activity funds paid by political parties to member lawmakers, a possible ban on political donations by companies and the disclosure of how research, public relations and accommodation allowances are used, the focus will be on whether consensuses can be reached on these issues in the extraordinary Diet session.
