Six parties are taking part, but the key battle is between the governing right-wing ARENA party and the former guerrilla movement FMLN led by a charismatic television journalist Mauricio Funes (pictured). Polls ahead of the election indicate the FMLN, will increase its 32-seat delegation in the 84-member legislature while keeping the capital and winning most of the 262 mayors' races.
President ElĂas Antonio Saca appealed for polling to go ahead in an orderly manner. The result will be seen as an indicator for presidential elections due in March.
