344 seats for Sarkozy

The parliament comprises 577 seats and therefore the absolute majority needed is 289 seats. The right wing has some 344 seats which are largely in excess of this figure and more than enough for Sarkozy/Fillon to push through their reforms. The fact that some media and opinion polls forecast an ever greater right-wing victory (400+) seats which failed to materialize is neither here nor there and is certainly not the fault of the politicians. The right has won and won well.

The majority has spoken and it would seem the majority in France leans conservatively. It's difficult for liberals and socialists to accept this and they continue to stir the pot. Regardless, Sarkozy is in power and enough of his party was elected to allow him to accomplish his goals.
