Guinea-Bissau votes on a stronger presidency: What’s at stake?

Voters in Guinea-Bissau will decide on August 30 whether to approve a new constitution that would significantly strengthen the presidency and reshape the country’s electoral system.

The vote comes nine months after the military seized power and installed General Horta Inta-A Na Man as transitional president, and just more than three months before presidential and legislative elections scheduled for December 6.

Supporters of the reform say it would provide clearer lines of authority and help address years of political instability and disputes between state institutions. Critics argue that it would concentrate too much power in the presidency and have questioned the process through which the draft was produced.

The African Party for the Independence of Guinea and Cape Verde (PAIGC), one of Guinea-Bissau’s main opposition parties, has rejected the referendum and called for a boycott.

The referendum will determine whether the constitution approved by the National Transitional Council (CNT) enters into force and provides the framework for the country’s return to elected government.

The process began after the November 26, 2025, military coup.

Presidential and legislative elections had been held three days earlier. The military seized power while the electoral process was still under way, one day before the electoral commission was due to announce the presidential results.

Horta, then army chief of staff, became transitional president.
