Belarus’ authoritarian President Alexander Lukashenko is all but certain to extend his more than three decades in power in Sunday’s election that is rejected by the opposition as a farce after years of sweeping repressions.

Belarusian leader and Russian ally Alexander Lukashenko extended his 31-year rule on Monday after electoral officials declared him the winner of a presidential election that Western governments rejected as a sham.

Belarusians are voting in a closely-managed presidential election that is all but certain to extend the one-man rule of Alexander Lukashenko, in power since 1994 and Europe’s longest-serving leader.

The E.U. has called Sunday’s election a sham. Lukashenko, running virtually unopposed, said he was “too busy” to even campaign.

Europe’s longest-serving leader won re-election in a contest widely believe to have been rigged. The result cements the power of a leader whose country is considered Russia’s staunchest ally.

Belarus “unilaterally” freed an American woman, Anastassia Nuhfer, from detention, U.S. Secretary of State Marco Rubio announced Sunday.
