Many Western leaders are decrying Belarusian President Alexander Lukashenko's re-election victory Sunday, calling it a sham along with the country's opposition.

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.

Belarus on Sunday held an orchestrated election virtually guaranteed to give its 70-year-old autocrat, Alexander Lukashenko, yet another presidential term on top of his three decades in power.
