Guinea-Bissau’s Referendum Puts Presidential Power at the Centre of Its Transition

Guinea-Bissau’s August 30 constitutional referendum has become a major test of whether the country’s military-led transition will restore democratic order or concentrate more power in the presidency before elections planned for December. Reuters reported on August 25, 2026 that the proposed constitution would expand presidential authority and reshape the rules for the next vote.

The referendum comes less than a year after military officers seized power in November 2025, one day before the electoral commission was due to announce presidential election results. Transitional authorities have said presidential and legislative elections are scheduled for December 6, 2026. The constitutional vote therefore lands at a sensitive point: before citizens choose new leaders, they are being asked to approve a new framework for how power will be organised.

According to a copy of the proposed constitution seen by Reuters, the president would be able 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 circumstances. The draft would also reduce parliament from 102 seats to 65 and cut electoral constituencies from 29 to 12.

Why the referendum matters

Guinea-Bissau has a long history of coups, attempted coups and institutional instability. Since independence from Portugal in 1974, the country has struggled to build durable civilian authority. Political competition has often been shaped by tensions between the presidency, parliament, the military and parties with regional or local bases.

That history makes constitutional design especially important. A constitution is not only a legal text. It distributes power, creates incentives and determines how political crises are resolved. In a country with repeated military interventions, a shift toward a stronger presidency must be examined carefully.

Supporters may argue that Guinea-Bissau needs clearer executive authority to overcome deadlock and unstable coalition politics. That argument has some local resonance because the country has faced repeated clashes between presidents and prime ministers. But stronger executive authority can also weaken checks and balances if the legislature is reduced and opposition parties lose institutional space.

The presidential shift

Under the current framework, Guinea-Bissau’s legislature has a major role in naming a prime minister who appoints a cabinet. The proposed constitution would give the president much greater control over the executive branch. That would move the country toward a more presidential system.

The danger is not presidentialism in itself. Many democracies have presidential systems. The danger is changing the rules under a military transition, before a disputed electoral process has been fully resolved and before civilian legitimacy has been restored.

Reuters quoted Manuel Nobre de Barros, a professor at Lusofona University in Guinea-Bissau, warning that the reduction in constituencies could curb parties with strong local bases and that the reforms would alter the balance of power between the president and legislature. His warning captures the central concern: the referendum may not only streamline government; it may narrow political competition.

Parliament and representation

The proposal to shrink parliament from 102 seats to 65 is significant. Smaller legislatures are not automatically undemocratic, but in fragmented societies they can reduce representation for smaller parties, regional groups and local interests. The effect depends on electoral rules, constituency design and party strength.

Reducing constituencies from 29 to 12 may also change who can compete effectively. Parties with concentrated local support could lose influence if constituencies become larger or less connected to local political identities. Larger constituencies can favour parties with national machinery, money and media access.

That is why the details matter. Citizens need to know not only that parliament will be smaller, but how representation will work in practice. Without clear public explanation, the reform risks being interpreted as a power-management exercise rather than a democratic reset.

The candidate-residency rule

Reuters reported that the proposed constitution would require presidential candidates to have resided permanently in Guinea-Bissau for the previous five years. The current constitution requires candidates to be citizens by birth, at least 35 years old and in full possession of civil and political rights, but does not include that five-year residence condition.

Residency requirements can be defended as a way to ensure candidates are connected to domestic life. But they can also be used to exclude exiled opposition figures, diaspora candidates or politicians who spent time abroad because of persecution, conflict or professional obligations.

In a country with repeated instability, political exile and displacement are not rare. Any new candidate rule should therefore be tested against its democratic effect. Does it strengthen accountability, or does it limit competition before voters can decide?

The military-transition problem

The referendum is taking place under military-led transitional authority. That makes the legitimacy threshold higher. Transitional governments are supposed to restore constitutional order, not entrench themselves or shape the next civilian system in a way that advantages favoured actors.

Punch reported in July that the junta set the August 30 referendum date after the Supreme Court issued a favourable opinion. Xinhua also reported that the referendum would ask voters whether the new constitution approved by the National Transitional Council should enter into force. Those legal steps matter, but legality and legitimacy are not identical. A lawful procedure can still be politically contested if the environment is constrained.

Key questions remain: Are opposition parties able to campaign freely? Is the media able to scrutinise the draft? Are voters informed about the changes? Is the electoral administration trusted? Is the military neutral? The credibility of the referendum depends on those answers.

West Africa is watching

Guinea-Bissau’s referendum comes in a region already marked by military takeovers, delayed transitions and debates over executive power. West Africa has seen coups in Mali, Burkina Faso, Guinea, Niger and Guinea-Bissau over recent years. Regional bodies have struggled to enforce consistent norms around timelines, civilian restoration and constitutional manipulation.

For ECOWAS and the African Union, Guinea-Bissau presents a familiar problem. A transition may promise elections while changing the rules before those elections happen. If regional organisations accept that without scrutiny, it can create a model for other transitional authorities.

The country is small compared with Nigeria or Ghana, but its precedent matters. Constitutional change under military rule can shape regional expectations about how far transition leaders can go before returning power to civilians.

The voter information test

Referendums can be democratic tools when citizens understand the proposal and can campaign for or against it freely. They can also become plebiscites that legitimise decisions already made by elites. Guinea-Bissau’s challenge is to prove that voters have meaningful choice.

IFES Election Guide notes that the referendum asks whether voters agree with the entry into force of the new constitution approved by the National Transition Council. A yes-or-no vote on an entire constitution is simple on the ballot but complex in substance. Voters may support some reforms and oppose others, yet the referendum bundles them together.

That places responsibility on transitional authorities, civil society, media and election observers to explain the stakes clearly. A constitutional referendum should not depend on slogans. Citizens need to understand how the presidency, parliament, candidate eligibility and elections would change.

What should happen next

First, Guinea-Bissau’s authorities should publish and distribute the full draft widely in accessible language before the vote. Citizens cannot judge a constitution they have not read or understood.

Second, the government should guarantee equal campaign space for supporters and opponents of the draft. A referendum under transition must be more transparent, not less.

Third, regional and domestic observers should assess the campaign environment as well as voting day. The fairness of the process begins before ballots are cast.

Fourth, the December election timetable should remain credible and public. Constitutional change should not become a reason to delay restoration of civilian rule.

Fifth, any new presidential powers should be balanced by strong judicial, parliamentary and electoral safeguards. Stability without accountability is fragile.

The bottom line

Guinea-Bissau’s August 30 referendum is not a technical constitutional exercise. It is a decision about the balance of power during a military-led transition and before planned December elections.

The proposed changes may promise clearer executive authority, but they also risk weakening parliamentary representation and narrowing electoral competition. That trade-off must be debated openly.

For Africa, the case is a reminder that constitutions written or approved during transitions can shape politics for years. Guinea-Bissau’s vote will test whether constitutional reform can rebuild legitimacy, or whether it becomes another route to concentrated power.
