Moderate Islamists claimed victory in Tunisia's first democratic election, sending a message to other states in the region that long-sidelined Islamists are challenging for power after the "Arab Spring".

Official results will be announced on Tuesday, but the Ennahda party said it had already tallied results posted at polling stations after Sunday's vote, the first since the uprisings which began in Tunisia and spread through the region.

"The first confirmed results show that Ennahda has obtained first place," campaign manager Abdelhamid Jlazzi said outside party headquarters in the centre of the Tunisian capital.

As he spoke, a crowd of more than 300 in the street shouted "Allahu Akbar!" or "God is greatest!". Other people started singing the Tunisian national anthem.

Mindful that some people in Tunisia and elsewhere see the resurgence of Islamists as a threat to modern, liberal values, party officials said they were prepared to form an alliance with two secularist parties, Congress for the Republic and Ettakatol.

"We will spare no effort to create a stable political alliance ... We reassure the investors and international economic partners," Jlazzi said.     
Two days after an unprecedented 90 percent of voters turned out for the election, officials were still counting the ballot papers in some areas. They said nationwide results would not be ready before Tuesday afternoon.

Sunday's vote was for an assembly which will sit for one year to draft a new constitution. It will also appoint a new interim president and government to run the country until fresh elections late next year or early in 2013.

The voting system has built-in checks and balances which make it nearly impossible for any one party to have a majority, compelling Ennahda to seek alliances with secularist parties, which will dilute its influence.

"This is an historic moment," said Zeinab Omri, a young woman in a hijab, or Islamic head scarf, who was outside the Ennahda headquarters when party officials claimed victory.

"No one can doubt this result. This result shows very clearly that the Tunisian people is a people attached to its Islamic identity," she said.     
Tunisia became the birthplace of the "Arab Spring" when Mohamed Bouazizi, a vegetable seller in a provincial town, set fire to himself in protest at poverty and government repression.     

His suicide in December provoked a wave of protests which forced autocratic president Zine al-Abidine Ben Ali to flee to Saudi Arabia the following month.

The revolution in Tunisia, a former French colony, in turn inspired uprisings which forced out entrenched leaders in Egypt and Libya, and convulsed Yemen and Syria -- re-shaping the political landscape of the Middle East.

Ennahda is led by Rachid Ghannouchi, forced into exile in Britain for 22 years because of harassment by Ben Ali's police.

A softly spoken scholar, he dresses in suits and open-necked shirts while his wife and daughter wear the hijab.

Ghannouchi is at pains to stress his party will not enforce any code of morality on Tunisian society, or the millions of Western tourists who holiday on its beaches. He models his approach on the moderate Islamism of Turkish Prime Minister Tayyip Erdogan.

The party's rise has been met with ambivalence by some people in Tunisia. The country's strong secularist traditions go back to the first post-independence president, Habiba Bourguiba.     

Outside the offices of the commission which organised the election, about 50 people staged a sit-in demanding an investigation into what they said were irregularities committed by Ennahda. Election officials said any problems were minor. - Reuters
