The party of Kyrgyzstan’s Moscow-backed prime minister claim he has won the country’s presidential election.
Almazbek Atambayev had been a favourite to win the ballot, and some reports say he already has more than 60 per cent of the votes.
Official counting continues, however, while other candidates claim there have been irregularities.
Opposition candidate Adakhan Madumarov said: “We said that we are all patriots of the Kyrgyz republic, and if there were fair and transparent elections, we would acknowledge them whatever results there would be. But as we see today’s lawlessness, we are ready to protect every single vote.”
The election is the result of reforms put in place after a bloody uprising toppled president Kurmanbek Bakiyev in April last year.
Russia and the US have military bases in Kyrgyzstan, which is moving towards more democracy after 20 years of authoritarian rule.
