RIYADH- Saudi Arabian women voted for the first time on Saturday in local council elections and also stood as candidates, a step hailed by some activists in the Islamic patriarchy as a historic change, but by others as merely symbolic."As a first step it is a great achievement. Now we feel we are part of society, that we contribute," said Sara Ahmed, 30, a physiotherapist entering a polling station in north Riyadh. "We talk a lot about it, it's a historic day for us."The election, which follows men-only polls in 2005 and 2011, is for two thirds of seats on councils that previously had only advisory powers, but will now have a limited decision making role in local government.This incremental expansion of voting rights has spurred some Saudis to hope the Al Saud ruling family, which appoints the national government, will eventually carry out further reforms to open up the political system.Saudi Arabia is the only country in which women cannot drive and a woman's male "guardian", usually a father, husband, brother or son, can stop her traveling overseas, marrying, working, studying or having some forms of elective surgery.
