Uruguayans are to elect their next president on Sunday in a close contest between former president Tabare Vazquez, 74, of the current centre-left ruling coalition and conservative Luis Lacalle Pou, 41, dpa reported. Polls are to open at 0900 and close at 2030 GMT. Until just recently, Vazquez seemed poised to take over as standard bearer for outgoing President Jose Mujica's centre-left Broad Front coalition. But as election day neared, it looked headed for a runoff on November 30 with no candidate near the majority needed to win outright, according to voter surveys.
