MEXICO CITY, Dec 4 (Reuters) - Mexico’s President Andres Manuel Lopez Obrador said on Friday he had delayed naming his nominee for a new central bank board member until Monday. Lopez Obrador, who has said the new member will be a woman, previously planned to announce on Friday the replacement for Javier Guzman, known as one of Mexican central bank’s more hawkish board members.
