By Mark Trevelyan (Reuters) -Belarusian leader Alexander Lukashenko was on track to extend his 31-year rule with a massive win in a presidential election on Sunday that Western governments rejected as a sham.

The smiling face of President Alexander Lukashenko gazed out from campaign posters across Belarus on Sunday as the country held an orchestrated election virtually guaranteed to give the 70-year-old autocrat yet another term on top of his three decades in power.

Exit polls have Alexander Lukashenko on track to extend his 31 year rule with nearly 88% of the vote. Western governments have slammed the vote as a sham, with Lukashenko's rivals broadly seen as government stooges.
