Voting has begun in Tunisia in the first free election of the Arab Spring, nine months after the fall of former President Zinedine el Abidine Ben Ali.
Tunisians will elect a 217-seat assembly that will draft a new constitution and appoint an interim government.
Islamist party Ennahda is expected to win the most votes, though it is not clear if it will gain a majority.
Campaigning in Tunisia has been marked by concerns over splits between Islamists and secularists, party funding and voter apathy.
But the BBC's correspondents there have reported widespread optimism and excitement as the campaign season drew to a close on Friday.
Ennahda, a moderate Islamist party, has sought to allay the fears of Tunisian secularists by stating its commitment to democracy and women's rights.
Its closest challenger is expected to be the secular, centrist Progressive Democratic Party.
Mr Ben Ali fled Tunisia in January amid the first of several mass uprisings across the Arab world. It was followed by the removal of the regimes in Egypt and Libya and mass protests in Syria, Bahrain and Yemen.
There are more than seven million people of voting age. More than 100 parties have registered to participate, along with a number of independent lists.
Hundreds of foreign election observers and thousands of local ones will be monitoring the poll.
The EU observer mission has said that the overall campaign has been transparent.
Results are expected by Monday.
The new assembly is expected to draft a new constitution within a year.
