Legislative elections were held in France on 10 June and 17 June 2007 to elect the 13th National Assembly of the Fifth Republic, a few weeks after the presidential election run-off on 6 May. 7,639 candidates stood for 577 seats, including France's overseas possessions. Early first-round results projected a large majority for President Nicolas Sarkozy's Union for a Popular Movement (UMP) and its allies; however, second-round results showed a closer race and a stronger left. Nevertheless, the right retained its majority from 2002 despite losing some 40 seats to the Socialists.

Taking place so shortly after the presidential poll, these elections provided the newly elected president with a legislative majority in line with his political objectives – as was the case in 2002, when presidential victor Jacques Chirac's UMP party received a large majority in the legislative elections. It is the first time since the 1978 elections that the governing coalition has been returned after a second consecutive election. The majority, however, was slimmer than the "blue wave" predicted by opinion polls (blue being the colour of French conservatives).

The procedure by which deputies are elected is a mixture of first past the post and run-off systems. A candidate must take an absolute majority (more than 50%) in their constituency to win in the first round, and receive the support of at least 25% of all registered voters. Otherwise, if they get at least 12.5% of the votes of all registered voters in the first round, or are one of the top two candidates remaining, they go through to the second round, where only a simple plurality is needed to win.

In most cases, there are only two candidates remaining for the second round: one left-wing (generally from the Socialist Party) and one right-wing (generally from the Union for a Popular Movement). Triangulaires happen when a third candidate reaches the second round and refuses to either abandon his candidacy or to enter any form of electoral alliance. In 2007, only one constituency experienced a triangulaire in the second round (in which Jean Lassalle, a MoDem candidate, was elected).

The Constitutional Council had beforehand warned the government of the necessity to renew the electoral map, as the 577 electoral districts are made on the basis of the 1982 census of the population (thus being 25 years late on the current spread-out of the population). Because of this miscorrelation between the electoral map and the geographical map of the population, a deputy would need only 5,000 votes to be elected in some districts (such as in Saint-Barthélemy) while it would need 180,000 votes in others (such as the Seine-Saint-Denis^[1]). The Constitutional Council noted that this contradicted article 6 of the 1789 Declaration of the Rights of Man and of the Citizen as well as articles 3 and 24 of the Constitution.^[2]

Opinion polls and seat projections gave President Nicolas Sarkozy's UMP-led coalition a wide lead, sometimes nearing three-quarters of all 577 seats. The UMP polled marginally above 40%, around a 10-point increase over its score of 33% in the first round of the 2002 elections. Prime Minister François Fillon, also a candidate in Sarthe, led the UMP campaign. On the far-right, following Jean-Marie Le Pen's relatively low score in the presidential election, the National Front tried to regain lost ground in the legislative election, but opinion polls gave the FN only 4 or 5 per cent of votes, one of its lowest scores in a general election.

Contrary to the polls, the UMP lost ground, but it maintained a workable majority. The Socialists unexpectedly gained seats. Their plea to voters to prevent an overwhelming UMP dominance of the legislature appears to have paid off, providing the Socialists with a measure of redemption from the election loss. UDF splinter groups, François Bayrou's MoDem and the New Centre, contested their first elections. MoDem won 4 seats (including Mayotte regionalist Abdoulatifou Aly), while the New Centre was able to form a parliamentary group, with 22 seats. It remains to be seen whether Bayrou's party, which polled the third highest vote (7.61% in round one), will develop into a major political force. Their result is an improvement on the UDF's result of 4.9% in 2002. The National Front (FN) polled its lowest vote since its splash onto the political scene in 1986. The FN lost more than 60% of its support base since 2002. Support for the Communist Party also declined, and they saw a loss of several seats, whilst several other left-wing parties won nine new seats. The Greens gained one new seat, despite a fall in their vote. One of the most stunning results was the surprise defeat of UMP party leader Alain Juppé by the Socialist Party candidate Michèle Delaunay. Culture Minister Renaud Donnedieu de Vabres was defeated as well losing to Socialist Party candidate Jean-Patrick Gille. The far right did not win any seats.
