CAIRO: Saudi Arabia's women on Sunday are bracing themselves for potential arrest as they defy a ban on driving in the ultra-conservative Gulf Kingdom. To mark the one-year anniversary of the Women2Drive campaign, Saudi women are expected to again take to the roads behind the wheel in protest against Riyadh's continued refusal to grant women the right to drive a vehicle in the country. Last year on June 17, some 100 women participated in the first ever demonstration of its kind, but many were arrested and jailed as a results. One woman's sentence of 10 lashes was revoked only after the king intervened and pardoned the woman. It was the largest mass action since November 1990, when 47 Saudi women were arrested after demonstrating in cars. On Wednesday, two founders of the movement, Manal al-Sharif, 33, and Najla Hariri, 45, posted an open letter with 600 signatories to King Abdullah, appealing once more for an end to the ban on women driving. The letter said: “Our initiative is not aimed at violating laws.” The petition asks for “the possibility for women to get a driving license in nearby countries and allowing them to start driving.” “Our initiative is not aimed at violating laws. We only want to enjoy the right to drive like all women over the world,” says the petition, signed by al-Sherif, who in 2011 launched an Internet campaign encouraging Saudi women to challenge the driving ban. She was arrested and sentenced to lashings by the government for driving in the country. Although she was pardoned, she has quickly become a symbol of Saudi women's empowerment as she continues to demand greater rights. The petition also asks the monarch to open driving schools in Saudi Arabia that can in future issue licenses to women. It thanked Aziz for giving women the right to vote in municipal elections starting in 2015.
