Biya, 93, has ruled the country since 1982, but his re-election was rejected by the opposition and led to demonstrations bloodily suppressed by the authorities.

The new polls come in a tense political context, marked by the repression of the opposition and the inertia of those in power at the top of the state.

The announcement was made in a decree read on public radio and follows two postponements of the elections.
