South Korea's National Assembly is due to hold a plenary session in the coming hours to vote on the government's extra budget... as well as a bill that calls for a special probe into an online opinion rigging scandal.<br /> The session had initially been rescheduled twice before being called off,... as rival parties were at odds over the specifics of the three-point-six billion U.S. dollar extra budget bill.<br />But, on Sunday evening,... they managed to fine-tune the details... with a subcommittee of the assembly's budget committee passing the revised version -- which is roughly 20 million dollars less than the initial proposal.<br /> Rival parties have also reached an agreement over the scope and duration of the special probe.<br />The parties had agreed to vote on both issues at the same time,... as part of a compromise to end six weeks of inactivity.<br />Rival parties agreed to hold a plenary session on Monday morning... on the premise that the deliberation of the extra budget is complete. <br />
