sentenced and deprived of civic rights etc.) The citizen designates a proxy, who must be a voter from the same commune. The designation of the proxy must be made before a legally capable witness: a judge, a judicial clerk, or an officier of judicial police, or, outside France, before an ambassador or consul. In the case of handicapped or severely ill people, an officer of judicial police or delegate thereof can be sent to the home of the citizen to witness the designation. The procedure is meant to avoid pressures on voters. Electoral system In all elections where there is a single official to be elected for a given area, including the two major national elections (the election of the President of the Republic and the election of the members of the National Assembly), two-round runoff voting is used. For elections to the European Parliament and some local elections, proportional voting is used. National Assembly The 577 members of the National Assembly are elected using a two-round system with single-member constituencies. To be elected in the first round, a candidate is required to secure an absolute majority of votes cast, and also to secure votes equal to at least 25% of eligible voters in their constituency. Should none of the candidates satisfy these conditions, a second round of voting ensues. Most constituencies proceed to a second round election. Only first-round candidates with the support of at least 12.5% of eligible voters are allowed to participate, but if only 1 candidate meets that standard the two candidates with the highest number of votes in the first round may continue to the second round. In the second round, the candidate with a plurality is elected. Of the 577 constituencies, 539 are in metropolitan France, 27 are in overseas departments and territories and 11 are for French citizens living abroad. Party primary elections Primary elections, within registered political parties, are used to select presidential candidates for the general election. Primaries also use two-round runoff voting when there are multiple candidates within a party. (see :Category:Primary elections in France). Open primaries, where any eligible voter may participate with minimal requirements, also occur. Voting procedures Voting is done using paper and manual counting. The voter gets pre-printed ballot papers () from a table at the entrance of the voting office (mail-in voting is not allowed in France). There is one ballot paper for each candidate,
