Tajik President Rakhmon set to win another term
Voters in Tajikistan have cast their ballots, with incumbent President Emomali Rakhmon widely expected to win a new seven-year term.
Mr Rakhmon, 61, faces five challengers, but the only genuine opposition candidate was barred from standing.
The authoritarian leader has been in office for more than 20 years in the impoverished former Soviet republic.
The EU and the US have not recognised a single election in the Central Asian country as free and fair.
Polls across the mountainous country were due to open at 01:00 GMT and close at 15:00 GMT.
Preliminary results are expected on Thursday. Tajikistan's official electoral commission has already declared the presidential election as valid.
The head of the electoral commission, Shermuhammad Shohiyon, told Tajik state television that 68% of registered voters had already cast their ballots by 14:00 local time (09:00 GMT) - easily surpassing the minimum 50% participation required to validate the vote.
Mr Rakhmon, who secured 79% of the vote in the 2006 election, did not campaign actively this time.
Instead, the president relied on extensive media coverage of his visits around the country, which his opponents say was heavily biased in his favour.
Election monitors complained when their bus turned up bearing a poster of the president on the windscreen. The bus company removed the poster.
The opposition accuses Mr Rakhmon - whose huge billboards are seen everywhere in the capital Dushanbe and other towns - of developing a personality cult. He denies the claim.
The five other presidential candidates have refrained from publicly criticising Mr Rakhmon.
Human rights activists Oynihol Bobonazarova - widely seen as the only genuine opposition candidate - was banned from the polls.
The electoral commission said earlier she had failed to collect the necessary 210,000 signatures of eligible voters to be officially registered.
Despite the expected easy victory, critics say Mr Rakhmon will face rising social tension in the country where some 50% of the population live in poverty.

Analysts say Tajikistan could also face further security challenges from Islamist groups in neighbouring Afghanistan after the planned pullout of the US-led forces next year.
