in 1961 both posts were elected simultaneously, and the BDG and UDSG agreed to run on a single united list under the name "National Union". No other party ran and the list won all 67 seats in the National Assembly, whilst M'ba ran unopposed for the presidency, and was elected with 100% of the vote. However, the two parties ran against each other in the 1964 parliamentary elections, with the BDG winning 31 seats to the UDSG's 16. The BDG was the only party to contest the 1967 general elections, resulting in M'ba being re-elected unopposed and the party winning all 47 seats in the National Assembly. The following year the country became a one-party state with the Gabonese Democratic Party (PDG, the successor to the BDG) as the sole legal party. General elections were held in 1969, with Omar Bongo (who had succeeded M'ba after his death in 1967) elected unopposed as President and the PDG list winning all 70 seats in the National Assembly. Presidential elections in 1979 and 1986 saw Bongo re-elected in the same manner, whilst the PDG remained unopposed in parliamentary elections in 1980 (in which the National Assembly was increased to 89 seats) and 1985 (111 seats). Multi-party politics was reintroduced in 1990 and parliamentary elections that year saw the PDG retain its majority in the National Assembly, although it was reduced to 63 of the 120 seats. The first competitive presidential elections were held in 1993, with Bongo re-elected with 51% of the vote, although the runner-up, Paul Mba Abessole, accused the government of vote rigging. The PDG won the 1996 parliamentary elections, winning 85 seats. The Senate was elected for the first time in early 1997, with the PDG winning 52 of the 91 seats. Bongo was re-elected again in 1998 with 67% of the vote, and the PDG gained another seat in the 2001 parliamentary elections. The February 2003 Senate elections saw the PDG win 67 of the 92 seats. Bongo was re-elected for a sixth time in the 2005 presidential elections with 79% of the vote. The PDG was reduced to 82 seats in the 2006 parliamentary elections, although affiliated parties won a further 17 seats. Senate elections in early 2009 saw the PDG win 75 of the 102 seats in an expanded Senate. Following Bongo's death in June 2009, presidential elections were held later in the year, and won
