LUSAKA (AFP): The trial of a Zambian musician charged with conduct likely to breach the peace over his song which accuses President Edgar Lungu of drinking too much, was on Wednesday postponed to July 13. Chama Fumba was arrested early this month over the song which some government officials allege was defamatory to the head of state because it accused Lungu of being incompetent. In an interview with AFP on Tuesday, Fumba - whose stage name is Pilato - denied allegations that his song was either defamatory or likely to have disturbed the peace.
