in late 1999, with a presidential runoff in January 2000. This time Ialá defeated the PAIGC candidate and acting President Malam Bacai Sanhá. The PRS emerged as the largest party in the National People's Assembly, but held only 38 of the 102 seats; the PAIGC finished third behind the Resistance of Guinea-Bissau-Bafatá Movement. Ialá was overthrown in a coup in September 2003, and after several delays, parliamentary elections were held in March 2004. The PAIGC re-emerged as the largest party, but failed to win a majority of seats and formed a government together with the PRS. Presidential elections were held the following year, and although Malam Bacai Sanhá of the PAIGC received the most votes in the first round, he was defeated by the now-independent candidate João Bernardo Vieira in the second. The next parliamentary elections were held in 2008 and resulted in a landslide victory for the PAIGC, which won 67 of the 100 seats. Vieira was assassinated in March 2009, and presidential elections resulted in a victory for Sanhá at the third attempt. Sanhá died in January 2012, and early elections were required to elect a successor. A first round was held in March, but the run-off between Carlos Gomes Júnior of the PAIGC and Ialá was cancelled after a military coup on 12 April. A transition to civilian rule was completed in 2014 after general elections saw José Mário Vaz become President after defeating independent candidate Nuno Gomes Nabiam in the runoff, whilst the PAIGC retained its parliamentary majority, winning 57 of the 102 seats in the expanded National People's Assembly. Electoral system President The President is elected using the two-round system. National People's Assembly The electoral system used between 1972 and 1989 involved voters electing regional councils, which in turn elected the members of the National People's Assembly. Voters were presented with a single list of PAIGC candidates to approve or vote against, although in some elections people voted for unofficial candidates. A voter turnout of at least 50% was required to validate the election in each sector. The country's current electoral law was passed on 15 May 1985. The National People's Assembly has 102 directly elected members; 100 are elected from 27 multi-member constituencies, with one single-member constituency representing citizens living abroad in Africa, and one for citizens living in Europe. Voters are required to be at least 18 years old and hold Guinea-Bissau citizenship,
