First woman is elected to Saudi local council
However, the election was for only two thirds of seats in municipal councils that have no lawmaking or national powers, and follows men-only polls in 2005 and 2011.
Otaibi won a seat in the Madrika district of Mecca, the holiest city of Islam, and where all the other successful candidates were men, the official Saudi Press Agency reported in a list of preliminary results.
Results from Northern Borders Province and the southwestern province of Asir, the only others to have been announced, had no successful women candidates.
Under King Abdullah, who died in January and who announced in 2011 that women would be able to vote in this election, steps were taken for women to have a bigger public role, sending more of them to university and encouraging female employment.
However, while women`s suffrage has in many other countries been a transformative moment in the quest for gender equality, its impact in Saudi Arabia is likely to be more limited due to a wider lack of democracy and continued social conservatism.
Before Abdullah announced women would take part in this year`s elections, the country`s Grand Mufti, its most senior religious figure, described women`s involvement in politics as "opening the door to evil"
