Paris  - The French Parliament on Monday approved a revision of the constitution that strengthens the role of the legislatures and limits the presidential mandate to two five-year terms.

In what is widely seen as a major victory for President Nicolas Sarkozy, both houses of parliament approved the measure by a vote of 539 to 357.

To become law, the amendment of the constitution had to be approved by two-thirds of the nearly 900 lawmakers gathered in special session in Versailles.

Eager to get the measure passed, Sarkozy had personally lobbied skeptical members of his own UMP party who had threatened to join opposition lawmakers in voting against it.

In addition to giving parliament additional powers, the measure also obliges the government to hold a referendum whenever a new country wishes to join the European Union.

This is broadly viewed as a tactic by Sarkozy to keep Turkey out of the Union. According to polls, the French are largely against Ankara joining the EU. (dpa)
