France's Socialists won control of parliament on Sunday, handing President Francois Hollande the convincing majority he needs to push through his tax-and-spend agenda to battle the Euro zone debt crisis.
The Socialists' bloc obtained 314 seats -- an absolute majority in the 577-seat National Assembly -- and so will not need to rely on the Greens or the far left, according to official results.
The far-right National Front was set to return to parliament for the first time since 1998 after winning two seats in the south of the country, although party leader Marine Le Pen lost her own bid for a seat.
Hollande, who defeated conservative Nicolas Sarkozy in a May presidential election, had urged voters to give him the MPs he needs to steer France through the Euro zone crisis, rising unemployment and a faltering economy.
The task before us is immense, Hollande's Prime Minister Jean-Marc Ayrault said as results came in from the run-off vote. Nothing will be easy.
The Socialists' absolute majority means they will be able to govern without backing of the far-left Left Front, whose positions are very different on Europe and the economy.
Beyond Hollande's election promises of job creation and tax hikes, the government will have to pass unpopular measures to bring the deficit below 3% of GDP, with no sign of the Euro zone debt crisis improving.
Sarkozy's UMP and its allies won 229 seats, the Socialist-allied Greens 17 seats and the Left Front 10, according to final results released by the interior ministry. While Le Pen's anti-immigrant and anti-EU National Front (FN) was set to return two MPs to parliament, she will not be among them.
The media spotlight was also focused on Segolene Royal, Hollande's former partner and mother of their four children, who conceded defeat in her battle after a dissident Socialist candidate refused to stand down.
Royal, whose campaign was shaken when Hollande's current partner Valerie Trierweiler tweeted her support for dissident Olivier Falorni, slammed what she called a political betrayal.
I ran a tough but straight and loyal campaign, she said in bitter but brief remarks in La Rochelle in western France.
While some commentators predicted the end of Royal's political career, the 2007 presidential candidate beaten by Sarkozy said she planned to continue to have an impact on national policy decisions.
The Socialists and allies won 50.34% of votes overall, interior ministry figures said, almost as high as the record 54% won shortly after Francois Mitterrand became France's last Socialist president in 1981.
With the French voting for the fourth time in eight weeks after electing their first Socialist president in 17 years, turnout was a record low for a second-round parliamentary vote at 56 percent.
Another record was beaten: the number of women elected. An unprecedented 155 women will take their places in the new National Assembly, compared to 107 in the previous election five years ago.
Already in control of the Senate and nearly all regional governments, the parliamentary majority gives the Socialists a free hand to implement reforms after the right urged voters to check the left's power in the polls.
Hollande heads to Mexico for G20 talks on Monday flush with electoral success and brandishing a further mandate to push for growth strategies -- rather than austerity measures -- to battle the Euro zone's debt crisis.
