ISTANBUL, Turkey, SPA -- Turks began voting on Sunday in a parliamentary election pitting the ruling Islamist-rooted AK Party against nationalists. Opinion polls tip the pro-business AK Party to govern alone for five more years, but the size of their majority will be key. Polling booths opened at 7 a.m. (0400 GMT) in east Turkey. In the west, including the capital Ankara and main commercial city Istanbul, they opened an hour later. Unofficial results are due after 9 p.m. (1800 GMT). Some 43 million Turks out of a population of 74 million can vote.--SPA www.spa.gov.sa/469390
