PORT-AU-PRINCE, Jan 23 (Reuters) - Two of Haiti's top leaders said on Friday they planned to proceed with a plan to remove Prime Minister Alix Didier Fils-Aime, though the timeline remained unclear, despite U.S. warnings against doing so in the last days of their mandate.

Speaking at a press conference, transitional presidential council member Edgar Leblanc Fils said the measure had been approved by a majority of the top executive body and would proceed through the following legal steps.

Speaking alongside him, fellow member Leslie Voltaire said there would be a "pause" for political groups to find an acceptable solution beyond the end of the government's mandate on February 7, by when the U.S. has said they must step down.
