**Votes are being counted in Kyrgyzstan’s presidential election, which the main opposition candidate has denounced as illegitimate alleging widespread fraud.**But the central election commission has ruled the vote valid.
Out of six candidates, two emerged as clear frontrunners - incumbent leader Kurmanbek Bakiyev and opposition candidate Almazbek Atambayev.
The Organisation for Security and Cooperation in Europe is to give its assessment of the process on Friday.
‘Carousel voters’
Late on Thursday, opposition supporters of Mr Atambayev gathered outside his campaign headquarters for a concert and to express their discontent with the election process.

Many said they witnessed widespread violations such as groups of so-called carousel voters moving from one polling station to another.
The crowd dispersed when leaders of the opposition reassured them that further actions would be taken in the coming days.
It is widely expected that incumbent President Bakiyev will win his second term in office after a high turnout and exit polls giving over 60% of votes in his favour.
Mr Bakiyev - who came to power four years ago off the back of a popular uprising which became known as the Tulip Revolution - had pledged to conduct free and fair elections.
But his political opponents claim their supporters have been threatened.
His main rival, Mr Atambayev, said he had to send his wife and daughter away from the country after being intimidated.
During Thursday’s vote, clashes between opposition members and government forces were reported in the northern town of Balykchi.
