Syrian opposition to hold runoff vote Saturday for new leader ISTANBUL (Reuters) - The Syrian opposition voted on Saturday to elect a new leader, but the top two candidates failed to gain a simple majority needed to become president of the coalition fighting to oust President Bashar al-Assad. A runoff ballot was scheduled for later on Saturday after Ahmad Jarba, a tribal figure linked with Saudi Arabia, and Mustafa al-Sabbagh, a businessman who is Qatar's point man, did not gain more than half of the votes in the 115 member Syrian National Coalition in an early morning ballot in Istanbul. The coalition is split into three power centers: the Muslim Brotherhood, the Sabbagh faction, and a Saudi-backed bloc that includes Jarba. The three factions held the vote for a new leader after failing to agree on a compromise candidate. Reporting by Khaled Yacoub Oweis; Editing by Philip Barbara
