Belarus’ authoritarian President Alexander Lukashenko has extended his more than three decades in power in an orchestrated weekend election that the opposition and the European Union rejected as a farce.

Alexander Lukashenko, who has ruled the ex-Soviet state for 31 years, held a four-hour press conference musing that some of his opponents "chose prison", after winning 88 per cent of the vote.

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.
