The PM wants to hear the parties' positions on the golden fiscal rule before the National Assembly gets around to voting on amendments to the Constitution that would put the rule in Slovenia's highest law.

Janša called the meeting after the presidency of the opposition Social Democrats (SD) failed to decide on Monday on whether to back the golden fiscal rule.

Initially the National Assembly was expected to meet for an extraordinary session to vote on the inclusion of the fiscal rule in the Constitution today.

The incorporation of the golden fiscal rule in the Constitution was endorsed by the relevant parliamentary Constitution Commission last week.

The changes were backed by all commission members bar MPs of the opposition Positive Slovenia (PS).

However, the SocDems appear split on the issue, with dissent growing in recent days against the position of leader Borut Pahor to back the constitutional amendment.

The meeting will also launch a debate on referendum-related constitutional changes. Most parties believe that the referendum legislation needs to be changed, however their views on what changes are needed vary.
