Campaign season for the final round of Haiti's elections has started, but the second-place finisher in the presidential vote has not yet announced whether he will participate in the runoff.

Jude Celestin told The Associated Press on Friday that "no decision has been made" about whether he will take part in the scheduled Dec. 27 runoff against Jovenel Moise.

Celestin says his team needs more time for dialogue with opposition factions that allege vote-rigging by election officials and Moise's government-backed campaign. He says he expects a decision soon.

Celestin and seven other presidential candidates have formed a disparate coalition after asserting that the October elections and ballot-counting process was too problematic for the count to be legitimate.
