Gabon's politics: a constitution that fixes its own rules in place

What Gabon's new constitution puts beyond amendment

The draft went to voters on 16 November 2024, fourteen months after the coup. The Constitutional Court validated the result on 29 November 2024: 91.6% in favour on a turnout of 54.2%, by the count International IDEA's democracy tracker reported that month. The provisional figures released a few days earlier by the military authorities' Committee for the Transition and Restoration of Institutions (CTRI) had put approval at 92% and turnout at about 54%. The text was promulgated in December 2024, and the World Bank's country overview dates the start of Gabon's Fifth Republic to the presidential election of April 2025 that followed it.

International IDEA describes a group of its provisions as eternity clauses, meaning they cannot be amended. The presidential term is one of them: seven years, renewable once. The amnesty for those who took part in the 2023 coup is another. The definition of marriage, restricted to two people of the opposite sex, is a third. The government issued the amnesty itself on 12 August 2025, so the constitution promised the protection nine months before the decree that granted it.

Beside these sit the provisions written against a dynasty. Britannica records that the text bars the spouses and descendants of a president from standing for election at the end of that president's term, and the World Bank describes it as excluding the spouses and direct descendants of former presidents. The BBC reported in November 2024 that candidates must also be exclusively Gabonese and have a Gabonese spouse. That condition, the BBC noted, effectively barred the deposed president, who is married to a French woman.

The text does not stop the leader of the military transition from standing, and IDEA said so in November 2024. Critics quoted by the BBC said the constitution was designed to let the coup leader remain in power, and others warned that it could concentrate too much power in the presidency. The transitional authorities described the referendum as a step towards the return to constitutional order.

How each Gabonese constitution was rewritten around the presidency

How Gabon went from two parties to one

At independence in 1960 there were two principal parties: the Gabonese Democratic Bloc (BDG) of Léon M'Ba and the Gabonese Democratic and Social Union (UDSG) of Jean-Hilaire Aubame. The first post-independence election, held under a parliamentary system, gave neither a majority. M'Ba became prime minister with the support of three of the four independent deputies, and the two leaders then agreed on a single list of candidates. In February 1961, under a new presidential system, M'Ba became president and Aubame foreign minister.

That partnership lasted until February 1963, when the BDG made the UDSG ministers choose between merging the parties and resigning. They resigned. M'Ba called an election for February 1964 and cut the National Assembly from 67 deputies to 47, and when the BDG looked set to win by default, the army removed him in a bloodless coup on 18 February 1964. French troops restored his government the next day.

The succession was then written into the text. A revision late in 1966 made the vice-president the automatic successor if the president died in office. In March 1967 M'Ba and Albert-Bernard Bongo were elected president and vice-president, and when M'Ba died that year Bongo took the office. The Guardian's obituary of Bongo records that Jacques Foccart, de Gaulle's adviser on African affairs, had been looking for a successor and judged that a young official who was not from the Fang majority and had no political base of his own would protect French interests.

In March 1968 Bongo dissolved the BDG and founded the Gabonese Democratic Party (PDG) as the only party. In April 1975 the vice-presidency was abolished and replaced by a prime minister with no right of automatic succession. The office that had carried Bongo into power was closed behind him.

How the multiparty text lost its term limits

Strikes and demonstrations by students and workers in early 1990 led to a national conference that March and April, attended by the PDG and 74 political organisations. It approved a Senate, freedom of assembly and of the press and the end of the exit visa. The first multiparty National Assembly elections in almost thirty years followed in September and October 1990, the Assembly voted unanimously in January 1991 for a law legalising opposition parties, and a new constitution with a bill of rights came into force in March 1991.

Amendments in 1997 created the Senate and the post of vice-president and extended the presidential term to seven years. In 2003 an amendment removed any limit on the number of terms, which allowed Omar Bongo to stand again in 2005. When he died on 8 June 2009, the president of the Senate, Rose Francine Rogombé, became interim president as the amended text provided.

His son's illness tested the text again. Ali Bongo was taken ill abroad in October 2018, and the constitution then provided that the president of the Senate would act as interim and organise an election within 60 days. In November 2018 the Constitutional Court amended the constitution itself to let the vice-president or the prime minister handle the president's duties, a step opposition leaders called illegal. In 2023 a further amendment cut the presidential term from seven years to five, by the BBC's account, and ISPI records that the rules were changed that year so that presidential, legislative and local elections would be held on the same day.

Why Gabonese presidential results were disputed so often

Every contested presidential election from 1993 onward ended with an official winner from the same family and an opposition that refused the figures. The shares below are the official results as the sources report them.

The 1993 vote was the first presidential election under the multiparty constitution. The opposition, which said its candidate Paul Mba Abessole had been robbed of victory, refused to validate the result, and the disturbances that followed were put down by the presidential guard. Talks hosted in Paris produced the accords of November 1994 and a government of national unity that soon broke down. A 50% devaluation of the currency in January 1994 set off protests in several cities in which about three dozen people were killed, according to Britannica.

The 2009 election was the first in Gabon's history without Omar Bongo on the ballot, and Wikipedia counts 18 contenders. The 2016 election is the one where the sources disagree most precisely. Jean Ping, a former chair of the African Union Commission, led as results came in; the last province to report was Haut-Ogooué, the Bongo family's home province. One account gives Ali Bongo 99.5% of its vote, another 95.5% on a reported turnout of 99.9%, and Britannica records a turnout there of more than 99% against a national turnout under 60%. In September 2016 the Constitutional Court cancelled the results from 21 polling stations, which widened the margin to 50.66% against 47.24%. Protesters set fire to the parliament building in Libreville, and in 2016 between 50 and 100 people were killed by the security forces and 1,000 arrested. An EU observation mission reported that the electoral rules benefited the incumbent.

In 2023 nineteen candidates were approved to stand. Alternance 2023, an alliance of six opposition parties, agreed on a single candidate, Albert Ondo Ossa, a little more than a week before the vote. Internet access was cut and a curfew imposed, and the result was read on state television at 3:30 in the morning on 30 August: 64.27% for the incumbent and 30.77% for Ondo Ossa. ISPI cites an alternative count of the 2023 vote at 1,000 polling stations that gave Ondo Ossa 68%.

How the Republican Guard ended the Bongo presidency

Minutes after the result was announced, around a dozen officers appeared on the state channel Gabon 24 in the name of the CTRI. They annulled the election, dissolved the institutions of the state and closed the borders, which reopened on 2 September 2023. Ali Bongo was placed under house arrest. His son Noureddin and the two most senior officials of the PDG were among those detained, and his wife Sylvia was later charged with money laundering and fraud. Brigadier General Brice Oligui Nguema, commander of the Republican Guard, was named head of the committee and sworn in as transitional president on 4 September 2023.

The takeover is read two ways, and both readings are on record. The officers' own account cited governance that risked pushing the country into chaos. Oligui Nguema told Le Monde that discontent had been growing since Ali Bongo's stroke in 2018 and named the third-term bid, the disregard of the constitution and the conduct of the election. ISPI reports him telling the French ambassador that the army no longer wanted to be used to kill Gabonese after each election.

The other reading starts from the family tree. Oligui Nguema is a cousin of the man he removed, and Albert Ondo Ossa called the coup a family affair and a palace revolution. ISPI traces a rivalry between the general and the first lady after the 2018 stroke and a contagion effect from the coups in Mali, Chad, Guinea, Burkina Faso and Niger since 2020. Crowds celebrated in Libreville and other cities, and the Alternance 2023 coalition at first thanked the army for standing up to what it called an electoral coup.

The transition was staffed from both sides of the old divide. On 7 September 2023 Raymond Ndong Sima, a former prime minister under Ali Bongo who had joined the opposition, was appointed to lead a government that included critics and Bongo-era figures and left out Alternance 2023. On 11 September the opposition politician Paulette Missambo was appointed to head a transitional Senate and Jean-François Ndongou, a minister under both Bongos, a transitional National Assembly. Ali Bongo was released on medical grounds, announced his retirement from politics in September 2024 and left for Angola with his family on 16 May 2025.

How Gabon is governed without a prime minister

The office of prime minister existed from April 1975, when it replaced the vice-presidency, until the 2024 constitution abolished it. The BBC reported that the new text introduces two vice-president posts in its place. An IMF staff team visiting Libreville from 14 to 25 September 2026 met the president and both vice-presidents along with the ministers of finance and planning, The executive it met had no head of government between the presidency and the ministers.

Under the 1991 text as amended, the president appointed and dismissed the prime minister and the cabinet, could dissolve the National Assembly, declare a state of siege, delay legislation and call referendums. The sources on file describe the 2024 text's abolition of the prime minister and its term rules and do not set out the rest of the president's powers clause by clause.

How parliament and the courts are made up

Parliament keeps two chambers. Britannica, as read in October 2026, lists a National Assembly of 145 seats and a Senate of 70, for a population the record puts at 2.3 million as of 2023. The pre-coup figures differ by source: the Wikipedia account of the old arrangement gives the Assembly 120 members, 111 elected in single-seat constituencies and nine appointed by the president, and a Senate of 91 elected for six years by local and departmental councillors, while Wikipedia's main article on the country puts the old Senate at 102. In 2023, before the coup, the PDG held more than 80% of the seats in parliament, according to ISPI.

Britannica records that the 2024 constitution provides for an independent judiciary made up of the Court of Cassation, courts of appeal, tribunal courts and administrative and financial courts, with a Constitutional Court as the highest authority on constitutional matters. Under the old text its nine judges served seven-year terms renewable once, three appointed by the president of the republic and three each by the presidents of the two chambers. A Constitutional Court trimmed the 2016 result and rewrote the succession rules in 2018. The coup leaders dissolved the institutions of the state in 2023, and a Constitutional Court then validated the referendum of 2024 and confirmed the presidential result of April 2025.

Who runs the provinces and the press

Gabon is divided into nine provinces, subdivided into prefectures and subprefectures, and the governors, prefects and subprefects are all appointed by the president. The provinces are Estuaire, Haut-Ogooué, Moyen-Ogooué, Ngounié, Nyanga, Ogooué-Ivindo, Ogooué-Lolo, Ogooué-Maritime and Woleu-Ntem. The government owns the daily L'Union, while most private titles appear weekly or less often. Many outlets were founded when multiparty politics returned in 1990, and the BBC cites Reporters Without Borders as saying that journalists commonly censor themselves.

How the transition returned Gabon to elected government

The transitional government announced on 13 November 2023 that presidential and legislative elections would be held in August 2025, with a timetable to be approved by a national conference in April 2024. The presidential vote came four months early, on 12 April 2025. Eight candidates stood, among them Oligui Nguema and Alain Claude Bilie-By-Nze, a former prime minister. Britannica records that Oligui Nguema won with more than 90% of the vote, that the Constitutional Court confirmed the result later that month and that he was sworn in on 3 May 2025 for a seven-year term.

The Commonwealth judged that the election "largely reflected the will of the people who voted and that it was conducted in a credible, transparent and inclusive manner", and restored Gabon to full membership in July 2025. Legislative, local and senatorial elections followed between September and October 2025, which the World Bank treats as the completion of the transition. A government reshuffle was announced in January 2026.

The amnesty for the coup's participants was issued on 12 August 2025, between the presidential vote and the legislative one. By then the man who had led the coup had been elected under a constitution that lists his amnesty among the clauses no later parliament may change.

Which alliances Gabon keeps and which suspended it

What the defence agreement with France held

The Guardian's 2009 obituary of Omar Bongo describes a presidency backed by a French military base and a defence agreement, the agreement that had been used when French troops reversed the overthrow of M'Ba in 1964. When the opposition leader Joseph Rendjambe was found dead in a hotel on 23 May 1990, rioting followed, the French consul-general and ten oil company employees were taken hostage and French troops evacuated foreigners. Britannica describes the French intervention at Port-Gentil as protecting French nationals and their property; the Wikipedia biography of Bongo says France helped keep him in power through Opération Requin. The Guardian, for its part, places a brief use of French troops in 1991 and says it was officially only to protect French citizens.

Paris also hosted the 1994 talks between Bongo and the opposition. The Guardian records that Bongo built allies in every party in Paris and used them to have reforming ministers removed, under Mitterrand in 1983 and under Sarkozy in 2008, and it suggested his death might mark the end of the relationship known as Françafrique. When the army removed his son in 2023, the French government condemned the coup and called for the annulled results to be respected; ISPI wrote that France and the United States were willing to accept it. The United States suspended several assistance programmes on 26 September 2023.

How Gabon came into the Commonwealth

In October 2012, shortly before a Francophonie summit, the presidential spokesman Alain-Claude Bilie By Nze said in Libreville that the government wanted to introduce English as a second official language, taught from nursery school. Gabon began applying to join the Commonwealth in 2020 and was admitted in June 2022, the same year as Togo. The coup brought a partial suspension that kept it out of the organisation's councils and meetings until the restoration of July 2025. The same man stood for the presidency in April 2025.

What the African blocs did after the coup

The African Union suspended Gabon on 31 August 2023, the day after the coup. The Economic Community of Central African States suspended Gabon on 5 September 2023 and moved its headquarters from Libreville to Malabo in Equatorial Guinea. The record dates Gabon's membership of the Francophonie to 1970, of the Organisation of Islamic Cooperation to 1974, the year after Omar Bongo converted to Islam, of the World Trade Organization to 1995 and of the CEMAC treaty to 25 June 1999.

Gabon followed a nonaligned foreign policy after independence and its president often acted as a mediator. Omar Bongo received the Dag Hammarskjöld Peace Prize in 1986 for his efforts on the Chad and Libya border conflict, and in December 1999 a peace accord he brokered was signed in the Republic of the Congo between the government and most leaders of an armed rebellion.
