The ruling and opposition parties agreed to begin a month-long parliamentary session this week to deal with pending bills, an opposition lawmaker said Monday.

Joo Seung-yong, floor leader of the minor opposition People's Party, said the three parties plan to hold plenary parliamentary sessions twice during the extraordinary session of the National Assembly that is set to run from Thursday through May 20.

He said the agreement was reached during his talks with his counterparts from the ruling Saenuri Party and the main opposition Minjoo Party

Joo said the three parties also agreed to hold working-level talks on a number of bills that they want to pass through the National Assembly.

The move came days after the ruling Saenuri Party suffered a crushing defeat in parliamentary elections in an apparent public backlash against the party's factional infighting.

The ruling party won 122 out of 300 seats while the Minjoo Party and the People's Party secured 123 and 38 seats, respectively. Seventeen other seats are held by another minor party members and independents. (Yonhap)
