Opposition parties on Monday indicated they might be ready to discuss an end to their Diet boycott following a request by prosecutors to strip lawmaker Muneo Suzuki of his parliamentary immunity from arrest.

Because the House of Representatives needs to approve a lawmaker's arrest while the Diet is in session, the ruling bloc apparently sees the procedure as a good opportunity to talk the opposition into ending the standoff, which began Thursday.

Members of the opposition camp say some concessions, such as a vote on a resolution calling for Suzuki's resignation, must be made if the ruling camp wants Diet business to return to normal.
