Meanwhile, the moderate political arm of the Muslim Brotherhood party only won three seats, or half of what it had in parliament.
Minority Shiites also gained another seat, giving them five Parliament members. Shiites constitute about one-quarter of the Kuwaiti population.
Amir Sheikh Sabah Al-Ahmed Al-Sabah dissolved the Parliament in March. Although Kuwait's parliament is relatively powerful compared to others in the region, tension with the royal family has often produced only deadlock with cabinet ministers appointed by the Amir.
Many Kuwaitis believe that the clashes between parliament and the appointed cabinet reflect the struggles within the ruling Al-Sabah family.
Kuwait voters expressed hope that the newly appointed Cabinet will work successfully with the newly elected Parliament to reignite economic progress for the oil-rich country, which pumps around two-and-one-half million barrels of oil per day.
Parliament, elected for a four-year term, has legislative powers to vote ministers out of office, but cannot bring down an entire cabinet. The Kuwaiti Amir remains the ultimate authority in the country.
