Zambian President Edgar Lungu has fired his special assistant for political affairs following pressure from the public.
No reasons was given for the dismissal of the scandal-ridden aide Kaizer Zulu.
In his place, President Lungu Friday appointed Chris Zimba as his new political advisor and urged him to "steer clear of trouble."
Zimba, a youthful academic from the University of Zambia, is a PhD student in politics and holds an Master in Democracy.
Mr Zulu's latest antics involved him instructing his "boys" to clobber a minibus driver after allegedly hitting him.
Police said they were investigating the matter but he was not summoned.
He later appeared on a TV talk show attempting to exonerate himself after much criticism.
Local media have reported incidents of himbrandishing a gun in public.
He also appeared in court recently on assault charges after an incident at a guest house in the capital Lusaka.
