French President Nicolas Sarkozy's right-wing party won an absolute majority in parliament on Sunday, results released by the Interior Ministry showed.
The second round of France's parliamentary elections ended at 8 p.m. (1800 GMT), with the Union for a Popular Movement (UMP) party taking 314 seats in the 577-seat National Assembly, or lower house of parliament.
The main opposition Socialist Party won 185 seats.
The remaining seats were shared by other parties, with For a Presidential Majority taking 22, Affiliated Rightists nine, Movement for France one, UDF-MoDem (centrists) three, Affiliated Leftists 15, Left Wing Radicals seven, Greens four, Communists 15 and others two.
The main far-right National Front won no seats in the election.
Turnout for the second round vote was 60 percent, almost the same as in the first round on June 10.
A total of 35.2 million registered voters were entitled to cast their ballots on Sunday.
Alain Juppe, environment minister and the government's No. 2, announced his resignation after losing a seat in the Gironde region of southwest France, as Prime Minister Francois Fillon has said any minister who failed to win his seat would have to quit.
After preliminary results of the election were published, Fillon said France had "made a clear and coherent choice" by giving Sarkozy "a majority to act."
"Your participation has resulted in a clear and coherent choice, which will allow the President of the Republic to implement his project," he said. "My dear compatriots, the time of elections is over, the time to unite has arrived, the time for action has begun."
He said the ruling party would unite all the French people to meet big challenges in the 21st century, adding that the government would keep its promises by launching a series of reform measures in such areas as economy, education, justice and labor system.
Socialist leader Francois Hollande expressed his satisfaction with the results, which he said indicated French citizens' demand for more "diversity and pluralism" in the French politics.
The Socialist Party, as "a useful opposition," would not only actively put forward measures in socioeconomic reforms, but also set itself against the government's "wrong decisions," he said.
