Guinea-Bissau’s Referendum Puts Presidential Power on Africa’s Democracy Watchlist

Guinea-Bissau votes on August 30 on a proposed constitution that would significantly expand presidential power, shrink parliament and reshape the rules for elections scheduled in December. The referendum is being organised during a military-led transition that began after the November 2025 coup, making the vote a major test of whether the country is moving back toward elected rule with stronger institutions or toward a more concentrated presidency.

Reuters reported that the proposed constitution would allow the president to appoint and dismiss the prime minister and cabinet, create or abolish ministries, chair the Council of Ministers, dissolve parliament during a grave political crisis and dismiss the government under certain conditions. The reform would also reduce parliament from 102 seats to 65 and cut electoral constituencies from 29 to 12.

Supporters present the draft as a way to end chronic gridlock in a country where conflict between presidents, prime ministers, parties and the military has repeatedly weakened governance. Critics argue that the referendum is being held under military authority, before elected institutions are restored, and that the proposed text gives the presidency too much control over the political system.

What voters are deciding

The referendum asks voters whether the new constitutional text should enter into force. That may sound procedural, but the decision would define the political architecture for the next elected government. Presidential and legislative elections are scheduled for December 6, so citizens are being asked to approve or reject the rules before choosing the leaders who would operate under them.

Under the existing system, Guinea-Bissau has a semi-presidential model in which the legislature plays a central role in producing the government. The proposed constitution would shift the balance sharply toward the presidency. A president elected in December would have direct authority over the prime minister, cabinet composition and ministerial structure. That would make the presidency the core of executive power.

The draft also changes representation. A smaller parliament and fewer constituencies could alter how local and regional interests are represented in Bissau. Reuters quoted Manuel Nobre de Barros, a professor at Lusofona University in Guinea-Bissau, warning that the reform could give the president virtually unchecked power and reduce the influence of parties with strong local bases.

Why the timing matters

The timing is central to the controversy. Guinea-Bissau is still under a military-led transition. General Horta Inta-A Na Man took power after the November 26, 2025 coup, which occurred one day before electoral authorities were expected to announce presidential election results. The African Union and ECOWAS suspended Guinea-Bissau after the coup, and regional bodies have continued to scrutinise the transition timetable.

Al Jazeera reported that the transitional framework bars the transitional president and prime minister from running in the December elections. That means the referendum is not simply a vote on Horta’s personal future. The more important question is what powers the next elected president would inherit.

Opposition parties and civil society groups see the sequence differently. Their concern is that a military-led authority is writing the next civilian order before voters have restored a fully elected parliament. The Africa Center for Strategic Studies described the referendum as an attempt by the junta to consolidate executive power and roll back power-sharing efforts in a country with a long record of instability.

A history of instability

Guinea-Bissau’s political system has been shaped by repeated coups, factional struggles and institutional paralysis. The country has experienced five coups since 1980 and numerous attempted coups or military interventions. Governments have often struggled to complete mandates, and disputes between presidents and prime ministers have frequently disrupted policy.

That history gives supporters of the reform a real argument. A clearer executive structure can reduce deadlock if institutions are weak and coalition politics becomes unmanageable. In theory, a stronger presidency could make government formation faster, clarify responsibility and reduce the frequency of institutional crises.

But the same history also explains the danger. Where military influence remains strong and checks are weak, concentrating power in one office can deepen instability rather than resolve it. If losing parties believe the rules are unfair, political conflict may move from parliament into the streets, courts, security forces or exile politics. A constitution that wins a vote but lacks broad legitimacy can become another source of crisis.

The opposition challenge

The African Party for the Independence of Guinea and Cape Verde, known as PAIGC, has rejected the referendum and called for a boycott, according to Al Jazeera. Opposition criticism focuses not only on the text but also on the political environment in which the vote is taking place. Civil society groups have questioned whether citizens can make a free constitutional choice while political activity remains restricted and key institutions are under transition control.

The Africa Center for Strategic Studies reported that civil society organisations had objected to a military-drafted constitution and warned about restrictions on political activity, independent media and opposition organisation. Those concerns matter because constitutional legitimacy depends on more than polling stations. It depends on debate, campaign access, media freedom and trust in electoral administration.

If turnout is low because of a boycott, a formal victory for the draft could still leave the country divided. If the draft is rejected, the transition authorities would need a new constitutional path before December. Either result will require political management beyond the referendum day.

Regional stakes

West Africa has spent recent years managing a series of military takeovers and democratic reversals. Mali, Burkina Faso, Niger and Guinea have all tested regional institutions, while ECOWAS has struggled to enforce norms consistently. Guinea-Bissau’s referendum therefore matters beyond its borders. It shows how military transitions can use constitutional reform as both a return-to-civilian-rule mechanism and a tool for reshaping power.

For ECOWAS and the African Union, the challenge is to encourage a credible transition without appearing to dictate domestic constitutional design. Regional bodies can insist on inclusive processes, election credibility and civilian rule. But they also need leverage, and that leverage has weakened across the region as some juntas have resisted external pressure.

If Guinea-Bissau completes a referendum and elections that are widely accepted, it could become a more stable case of transition management. If the process is rejected by major political actors, the country may enter December with deeper legitimacy problems.

What to watch next

The first signal will be turnout. A high turnout would strengthen whichever outcome voters choose. A low turnout, especially if driven by opposition boycotts, would raise questions about legitimacy even if the official result is decisive.

The second signal will be how the authorities handle the campaign, polling, counting and publication of results. Transparent procedures, independent observation and quick publication of detailed results would help reduce suspicion. Delays, restrictions or opaque tabulation would increase tension.

The third signal will be the reaction from opposition parties, civil society, ECOWAS and the African Union. If those actors accept the result, the December elections can become the main focus. If they reject it, the referendum may become the opening stage of a broader constitutional dispute.

The fourth signal will be whether the December election calendar remains intact. The transition authorities have said elections are planned for December 6. Any delay after the referendum would revive concerns that constitutional reform is being used to extend military influence.

The bottom line

Guinea-Bissau’s referendum is a decisive political moment for one of Africa’s most coup-prone states. The proposed constitution promises clearer executive authority, but it also concentrates power in the presidency at a time when elected institutions have not yet been restored.

The central issue is legitimacy. A constitution can reduce gridlock only if major political actors believe the rules are fair enough to follow. If the referendum is seen as a military-managed shortcut, it could deepen the very instability it is meant to solve.

For Africa, the vote is another test of how constitutional reform should happen after coups. Returning to elections is important, but the rules of return matter just as much. Guinea-Bissau now faces a choice not only about presidential power, but about the kind of civilian politics it wants after military rule.
