A commission probing Haiti's disputed presidential election says a first-round vote was plagued by irregularities, but that a final run-off can take place as scheduled in two weeks.

The report delivered Sunday says the Oct. 25 contest between 54 candidates was "stained by irregularities," in which poll watchers intervened to help several candidates, whom it doesn't name. It recommends possible legal action against those involved and new measures to ensure transparency for the July 17 vote.

Opposition parties dispute official results showing pro-government candidate Moise Jovenel topping the October vote. He's due to confront second-place finisher Jude Celestin, who also has challenged the official count.

Haiti's electoral council postponed the runoff, which was initially set for December, and the government named the commission in hopes of calming the electoral dispute.
