The ruling and main opposition parties are discussing ways the government could issue debt to fund the annual budget without having to legislate this authority, to avoid future replays of the current standoff obstructing public expenditures, sources said.

The negotiations — launched earlier this month between Prime Minister Yoshihiko Noda's Democratic Party of Japan, and the Liberal Democratic Party and New Komeito — are expected to see new regulations created to cover the five years from next April, the sources said.

The three parties are considering modifying additional clauses of the debt bill that Noda's Cabinet has submitted to the Diet, aiming to secure the consent of their respective policy chiefs as early as Monday.
