French Prime Minister Jean-Marc Ayrault on Tuesday called on left parliamentary majority to help reshaping the eurozone through their green light to pave the way for official ratification of the European fiscal pact.

Submitting the new EU budget discipline to the the National Aseembly, Ayrault asked deputies "to vote on the treaty's ratification" as "through your vote is on the reorientation of Europe you will rule," he addressed legislators.

"Responsibility to which each of us needs to assume is that of keeping France in a consolidated eurozone because the consequence of a negative vote in our country, it would be, you know, a political crisis and the collapse of the monetary union," he warned.

Working hard to pass the controversial fiscal pact, the socialist government hoped to approve the treaty without the need of conservative voices after allies from Left and Greens said to block further prescribed austerity.

On the streets, people and some political figures expressed their reservation, saying ansterity measures would hit further struggling economies. Last Sunday thousands of demonstarators headed by by Jean-Luc Melenchon, the leader of the Left Party, took the streets of Paris to protest against the new treaty.

Agreed last March by former president Nicolas Sarkozy and 24 other European leaders, the EU fiscal pact requires eurozone countries to trim their budget gaps or face sanctions aimed at restoring faith in the future of the single currency.
