Guinea voters overwhelmingly approved a new constitution that could permit coup leader Mamady Doumbouya to run for president, according to partial results released Monday.

The constitution looked set to pass with 90.6% votes in favor and 9.4% against, Djenabou Toure, head of Guinea's General Directorate of Elections, told reporters. Those figures were based on roughly 91% of votes cast in the referendum.

An overall figure for voter turnout was not available but officials had counted more than 4.8 million votes out of more than 6.6 million registered voters, meaning turnout had exceeded 70%.

Doumbouya seized power in Guinea, home to the world's largest reserves of bauxite, in 2021. It was part of a wave of eight coups that swept West and Central Africa between 2020 and 2023.

A charter adopted after the coup barred members of the transitional government from seeking office.
