Veteran Libyan diplomat Ali Treiki has resigned from official duties, Arab League sources in Cairo said on Sunday, the latest in a string of officials to abandon the regime of Moamer Gaddafi.
Treiki, who represented Libya at the United Nations and a former foreign minister, held talks on Sunday in Cairo with Arab League chief Amr Mussa but refused to make any press statements.
He has resigned his official duties but did not pledge alliegance to the rebels fighting to overthrow Gaddafi, a league source said.
He is the second high profile official to resign this week, after the defection of foreign minister and Gaddafi regime stalwart Mussa Kussa.
Kussa arrived in Britain from Tunisia on Wednesday, dealing a major blow to the Libyan regime as it faced a Western-led aerial assault backed by a UN Security Council resolution authorising the protection of civilians by all means.
