The head of Libyas national unity government plans to run for president next month, according to a senior official. Abdulhamid al-Dbeibah and other cabinet members had pledged not to run for president when they were appointed to the Government of National Unity, which replaced two rival administrations after years of war between factions based in the east and west. Dbeibah "announced his intention to run for the upcoming presidential election," the senior official told Reuters, a day before registration for candidates officially opens. Libyas rival political institutions remain divided over the elections legal basis, the rules governing candidacy and even the date. Libyas High National Elections Commission said it would open registration on Monday for candidates in presidential and parliamentary elections that have been mandated by a UN-backed roadmap on Dec. 24.
