Iraqi Kurdistan presents itself as a relative oasis of stability in the turbulent Middle East, attracting foreign investors due to its close ties with the United States and Europe.

However, activists and opposition figures contend that the region, autonomous since 1991, faces the same issues affecting Iraq as a whole: corruption, political repression and cronyism among those in power.

Originally scheduled for two years ago, the vote was postponed four times due to disputes between the region's two historic parties, the Kurdistan Democratic Party (KDP) and the Patriotic Union of Kurdistan (PUK).

Each party is controlled by a powerful Kurdish family -- the KDP by the Barzanis and the PUK by the Talabanis.

Despite holding election rallies and mobilising their patronage networks, experts say there is widespread public disillusionment with the parties, exacerbated by the region's bleak economic conditions.

Polls closed at 6:00 PM (1500 GMT) and official results were expected 24 hours later.

Huri Mohammed, a 66-year-old housewife, said she voted for the KDP which dominates the regional capital Arbil, as it "serves the people".

But she expressed hope the next government would "pay attention to the poor classes. The majority of our population has limited means".

Opposition parties such as New Generation and a movement led by Lahur Sheikh Jangi, a dissident from the Talabani clan, may gain from a protest vote, said Sarteep Jawhar, a PUK dissident and political commentator.

Hiwa Hadi, a candidate for the newly formed opposition Halwest party, said after voting in Arbil: "People are dissatisfied and angry due to rising prices and taxes, electricity and water shortages".

Political analyst Shivan Fazil, a PhD student at the US-based Boston University, noted that there was "a growing fatigue with the region's two ruling parties".

Fazil, who focuses on Iraq, said people's living conditions "have deteriorated over the last decade".

Salaries for the region's 1.2 million civil servants are "a vital source of income for households" but payment of the money has been erratic, Fazil said.

This issue is tied to ongoing tensions between Kurdistan and the federal Iraqi government in Baghdad, amid disputes over control of the region's lucrative oil exports.

The creation of four new constituencies for this election -- a change from only one previously -- "could lead to redistribution in vote shares and seats in the next parliament", Fazil said.

He still predicted, however, that the KDP could maintain its power.

The KDP is the largest party in the outgoing parliament, with 45 seats against 21 for the PUK. The KDP's majority was assured by an alliance with deputies elected via a quota reserved for Turkmen, Armenian and Christian minorities.

Iraqi court rulings have reduced the number of seats in the Kurdish parliament from 111 to 100, but with five seats still reserved for the minorities.

Of the region's six million inhabitants, 2.9 million were eligible to vote for the 100 representatives, including 30 women mandated by a quota.

Once voted in, the new representatives will need to elect a new president and prime minister. The roles are currently filled by KDP figures Nechirvan Barzani and his cousin, Masrour Barzani.

In Baghdad on Sunday evening, Iraqi President Mohammed Shia al-Sudani called the vote a "success" and expressed hope for development and "stability" under a new regional government.

Mohamed al-Hassan, the United Nations special representative in Iraq, welcomed the election as an opportunity for the Kurdistan region to "reinvigorate democracy and inject new ideas into its institutions".

But 55-year-old teacher Sazan Saduala said she was boycotting the election.

"This government cannot be changed by voting," she said. "It maintains its power through force and money."
