President John Magufuli yesterday revoked the appointment of Permanent Secretary of the Ministry of Energy and Minerals, Prof Justin Ntalikwa.
The Directorate of Presidential Communications however did not give the reason behind the dismissal of Prof Ntalikwa who has served in the position for over a year.
He has been shown the exit door few days after President Magufuli made an impromptu visit to the Dar es Salaam port where he witnessed containers full of mineral sand for export against his ban early this month.
After the ban, the president directed Energy and Minerals Minister Professor Sospeter Muhongo to fully enforce the sanction.
Signed by the Director of the Presidential Communications, Mr Gerson Msigwa, the statement said the vacant post would be filled later.
