Japan's extraordinary parliament session is likely to be convened on Oct. 3, a ruling party lawmaker said Tuesday, in what would be the first Diet debate since Prime Minister Fumio Kishida reshuffled his Cabinet in early August.

During the session, the Liberal Democratic Party and its junior coalition partner, Komeito, are set to seek the passage of a second supplementary budget for the fiscal year through March 2023, centering on a new relief package to tackle rising price hikes.

The ruling bloc will also try to enact other bills related to the COVID-19 pandemic, such as one aimed at ensuring adequate hospital beds and medical supplies for COVID-19 patients, according to the source.
